+		this file, the device bus type's .online() callback is executed
+		for the device and (if successful) its 'offline' field is
+		updated as appropriate.
+
+		After a successful execution of the bus type's .offline()
+		callback the device cannot be used for any purpose until either
+		it is removed (i.e. device_del() is called for it), or its bus
+		type's .online() is exeucted successfully.

-    <para>For driver debugging purposes this ioctl allows test
-applications to query the driver about the chips present on the TV
-card. Regular applications must not use it. When you found a chip
-specific bug, please contact the linux-media mailing list (&v4l-ml;)
-so it can be fixed.</para>
-
-    <para>To query the driver applications must initialize the
-<structfield>match.type</structfield> and

-fields of a &v4l2-dbg-chip-ident;

-this structure. On success the driver stores information about the
-selected chip in the <structfield>ident</structfield> and
-<structfield>revision</structfield> fields. On failure the structure
-remains unchanged.</para>
-
-    <para>When <structfield>match.type</structfield> is
-<constant>V4L2_CHIP_MATCH_HOST</constant>,
-<structfield>match.addr</structfield> selects the nth non-&i2c; chip

+ACPI Device Tree - Representation of ACPI Namespace

+Abstract:
+
+The Linux ACPI subsystem converts ACPI namespace objects into a Linux
+device tree under the /sys/devices/LNXSYSTEM:00 and updates it upon
+receiving ACPI hotplug notification events.  For each device object in this
+hierarchy there is a corresponding symbolic link in the
+/sys/bus/acpi/devices.
+This document illustrates the structure of the ACPI device tree.

+1. ACPI Definition Blocks
+
+   The ACPI firmware sets up RSDP (Root System Description Pointer) in the
+   system memory address space pointing to the XSDT (Extended System
+   Description Table).  The XSDT always points to the FADT (Fixed ACPI
+   Description Table) using its first entry, the data within the FADT
+   includes various fixed-length entries that describe fixed ACPI features
+   of the hardware.  The FADT contains a pointer to the DSDT
+   (Differentiated System Descripition Table).  The XSDT also contains
+   entries pointing to possibly multiple SSDTs (Secondary System
+   Description Table).
+
+   The DSDT and SSDT data is organized in data structures called definition
+   blocks that contain definitions of various objects, including ACPI
+   control methods, encoded in AML (ACPI Machine Language).  The data block
+   of the DSDT along with the contents of SSDTs represents a hierarchical
+   data structure called the ACPI namespace whose topology reflects the
+   structure of the underlying hardware platform.
+
+   The relationships between ACPI System Definition Tables described above
+   are illustrated in the following diagram.

+                     Figure 1. ACPI Definition Blocks
+
+   NOTE: RSDP can also contain a pointer to the RSDT (Root System
+         Description Table).  Platforms provide RSDT to enable
+         compatibility with ACPI 1.0 operating systems.  The OS is expected
+         to use XSDT, if present.
+
+
+2. Example ACPI Namespace
+
+   All definition blocks are loaded into a single namespace.  The namespace
+   is a hierarchy of objects identified by names and paths.
+   The following naming conventions apply to object names in the ACPI
+   namespace:
+   1. All names are 32 bits long.
+   2. The first byte of a name must be one of 'A' - 'Z', '_'.
+   3. Each of the remaining bytes of a name must be one of 'A' - 'Z', '0'
+      - '9', '_'.
+   4. Names starting with '_' are reserved by the ACPI specification.
+   5. The '\' symbol represents the root of the namespace (i.e. names
+      prepended with '\' are relative to the namespace root).
+   6. The '^' symbol represents the parent of the current namespace node
+      (i.e. names prepended with '^' are relative to the parent of the
+      current namespace node).
+
+   The figure below shows an example ACPI namespace.

+3. Linux ACPI Device Objects
+
+   The Linux kernel's core ACPI subsystem creates struct acpi_device
+   objects for ACPI namespace objects representing devices, power resources
+   processors, thermal zones.  Those objects are exported to user space via
+   sysfs as directories in the subtree under /sys/devices/LNXSYSTM:00.  The
+   format of their names is <bus_id:instance>, where 'bus_id' refers to the
+   ACPI namespace representation of the given object and 'instance' is used
+   for distinguishing different object of the same 'bus_id' (it is
+   two-digit decimal representation of an unsigned integer).
+
+   The value of 'bus_id' depends on the type of the object whose name it is
+   part of as listed in the table below.
+

+
+                 Table 1. ACPI Namespace Objects Mapping
+
+   The following rules apply when creating struct acpi_device objects on
+   the basis of the contents of ACPI System Description Tables (as
+   indicated by the letter in the first column and the notation in the
+   second column of the table above):
+   N:
+      The object's source is an ACPI namespace node (as indicated by the
+      named object's type in the second column).  In that case the object's
+      directory in sysfs will contain the 'path' attribute whose value is
+      the full path to the node from the namespace root.
+      struct acpi_device objects are created for the ACPI namespace nodes
+      whose _STA control methods return PRESENT or FUNCTIONING.  The power
+      resource nodes or nodes without _STA are assumed to be both PRESENT
+      and FUNCTIONING.
+   F:
+      The struct acpi_device object is created for a fixed hardware
+      feature (as indicated by the fixed feature flag's name in the second
+      column), so its sysfs directory will not contain the 'path'
+      attribute.
+   M:
+      The struct acpi_device object is created for an ACPI namespace node
+      with specific control methods (as indicated by the ACPI defined
+      device's type in the second column).  The 'path' attribute containing
+      its namespace path will be present in its sysfs directory.  For
+      example, if the _BCL method is present for an ACPI namespace node, a
+      struct acpi_device object with LNXVIDEO 'bus_id' will be created for
+      it.
+
+   The third column of the above table indicates which ACPI System
+   Description Tables contain information used for the creation of the
+   struct acpi_device objects represented by the given row (xSDT means DSDT
+   or SSDT).
+
+   The forth column of the above table indicates the 'bus_id' generation
+   rule of the struct acpi_device object:
+   _HID:
+      _HID in the last column of the table means that the object's bus_id
+      is derived from the _HID/_CID identification objects present under
+      the corresponding ACPI namespace node. The object's sysfs directory
+      will then contain the 'hid' and 'modalias' attributes that can be
+      used to retrieve the _HID and _CIDs of that object.
+   LNXxxxxx:
+      The 'modalias' attribute is also present for struct acpi_device
+      objects having bus_id of the "LNXxxxxx" form (pseudo devices), in
+      which cases it contains the bus_id string itself.
+   device:
+      'device' in the last column of the table indicates that the object's
+      bus_id cannot be determined from _HID/_CID of the corresponding
+      ACPI namespace node, although that object represents a device (for
+      example, it may be a PCI device with _ADR defined and without _HID
+      or _CID).  In that case the string 'device' will be used as the
+      object's bus_id.
+
+
+4. Linux ACPI Physical Device Glue
+
+   ACPI device (i.e. struct acpi_device) objects may be linked to other
+   objects in the Linux' device hierarchy that represent "physical" devices
+   (for example, devices on the PCI bus).  If that happens, it means that
+   the ACPI device object is a "companion" of a device otherwise
+   represented in a different way and is used (1) to provide configuration
+   information on that device which cannot be obtained by other means and
+   (2) to do specific things to the device with the help of its ACPI
+   control methods.  One ACPI device object may be linked this way to
+   multiple "physical" devices.
+
+   If an ACPI device object is linked to a "physical" device, its sysfs
+   directory contains the "physical_node" symbolic link to the sysfs
+   directory of the target device object.  In turn, the target device's
+   sysfs directory will then contain the "firmware_node" symbolic link to
+   the sysfs directory of the companion ACPI device object.
+   The linking mechanism relies on device identification provided by the
+   ACPI namespace.  For example, if there's an ACPI namespace object
+   representing a PCI device (i.e. a device object under an ACPI namespace
+   object representing a PCI bridge) whose _ADR returns 0x00020000 and the
+   bus number of the parent PCI bridge is 0, the sysfs directory
+   representing the struct acpi_device object created for that ACPI
+   namespace object will contain the 'physical_node' symbolic link to the
+   /sys/devices/pci0000:00/0000:00:02:0/ sysfs directory of the
+   corresponding PCI device.
+
+   The linking mechanism is generally bus-specific.  The core of its
+   implementation is located in the drivers/acpi/glue.c file, but there are
+   complementary parts depending on the bus types in question located
+   elsewhere.  For example, the PCI-specific part of it is located in
+   drivers/pci/pci-acpi.c.
+
+
+5. Example Linux ACPI Device Tree
+
+   The sysfs hierarchy of struct acpi_device objects corresponding to the
+   example ACPI namespace illustrated in Figure 2 with the addition of
+   fixed PWR_BUTTON/SLP_BUTTON devices is shown below.

+ACPI video extensions
+~~~~~~~~~~~~~~~~~~~~~
+
+This driver implement the ACPI Extensions For Display Adapters for
+integrated graphics devices on motherboard, as specified in ACPI 2.0
+Specification, Appendix B, allowing to perform some basic control like
+defining the video POST device, retrieving EDID information or to
+setup a video output, etc.  Note that this is an ref. implementation
+only.  It may or may not work for your integrated video device.
+
+The ACPI video driver does 3 things regarding backlight control:
+
+1 Export a sysfs interface for user space to control backlight level
+
+If the ACPI table has a video device, and acpi_backlight=vendor kernel
+command line is not present, the driver will register a backlight device
+and set the required backlight operation structure for it for the sysfs
+interface control. For every registered class device, there will be a
+directory named acpi_videoX under /sys/class/backlight.
+
+The backlight sysfs interface has a standard definition here:
+Documentation/ABI/stable/sysfs-class-backlight.
+
+And what ACPI video driver does is:
+actual_brightness: on read, control method _BQC will be evaluated to
+get the brightness level the firmware thinks it is at;
+bl_power: not implemented, will set the current brightness instead;
+brightness: on write, control method _BCM will run to set the requested
+brightness level;
+max_brightness: Derived from the _BCL package(see below);
+type: firmware
+
+Note that ACPI video backlight driver will always use index for
+brightness, actual_brightness and max_brightness. So if we have
+the following _BCL package:
+
+Method (_BCL, 0, NotSerialized)
+{
+	Return (Package (0x0C)
+	{
+		0x64,
+		0x32,
+		0x0A,
+		0x14,
+		0x1E,
+		0x28,
+		0x32,
+		0x3C,
+		0x46,
+		0x50,
+		0x5A,
+		0x64
+	})
+}
+
+The first two levels are for when laptop are on AC or on battery and are
+not used by Linux currently. The remaining 10 levels are supported levels
+that we can choose from. The applicable index values are from 0 (that
+corresponds to the 0x0A brightness value) to 9 (that corresponds to the
+0x64 brightness value) inclusive. Each of those index values is regarded
+as a "brightness level" indicator. Thus from the user space perspective
+the range of available brightness levels is from 0 to 9 (max_brightness)
+inclusive.
+
+2 Notify user space about hotkey event
+
+There are generally two cases for hotkey event reporting:
+i) For some laptops, when user presses the hotkey, a scancode will be
+   generated and sent to user space through the input device created by
+   the keyboard driver as a key type input event, with proper remap, the
+   following key code will appear to user space:
+
+	EV_KEY, KEY_BRIGHTNESSUP
+	EV_KEY, KEY_BRIGHTNESSDOWN
+	etc.
+
+For this case, ACPI video driver does not need to do anything(actually,
+it doesn't even know this happened).
+
+ii) For some laptops, the press of the hotkey will not generate the
+    scancode, instead, firmware will notify the video device ACPI node
+    about the event. The event value is defined in the ACPI spec. ACPI
+    video driver will generate an key type input event according to the
+    notify value it received and send the event to user space through the
+    input device it created:
+
+	event		keycode
+	0x86		KEY_BRIGHTNESSUP
+	0x87		KEY_BRIGHTNESSDOWN
+	etc.
+
+so this would lead to the same effect as case i) now.
+
+Once user space tool receives this event, it can modify the backlight
+level through the sysfs interface.
+
+3 Change backlight level in the kernel
+
+This works for machines covered by case ii) in Section 2. Once the driver
+received a notification, it will set the backlight level accordingly. This does
+not affect the sending of event to user space, they are always sent to user
+space regardless of whether or not the video module controls the backlight level
+directly. This behaviour can be controlled through the brightness_switch_enabled
+module parameter as documented in kernel-parameters.txt. It is recommended to
+disable this behaviour once a GUI environment starts up and wants to have full
+control of the backlight level.

+dm-switch
+=========
+
+The device-mapper switch target creates a device that supports an
+arbitrary mapping of fixed-size regions of I/O across a fixed set of
+paths.  The path used for any specific region can be switched
+dynamically by sending the target a message.
+
+It maps I/O to underlying block devices efficiently when there is a large
+number of fixed-sized address regions but there is no simple pattern
+that would allow for a compact representation of the mapping such as
+dm-stripe.
+
+Background
+----------
+
+Dell EqualLogic and some other iSCSI storage arrays use a distributed
+frameless architecture.  In this architecture, the storage group
+consists of a number of distinct storage arrays ("members") each having
+independent controllers, disk storage and network adapters.  When a LUN
+is created it is spread across multiple members.  The details of the
+spreading are hidden from initiators connected to this storage system.
+The storage group exposes a single target discovery portal, no matter
+how many members are being used.  When iSCSI sessions are created, each
+session is connected to an eth port on a single member.  Data to a LUN
+can be sent on any iSCSI session, and if the blocks being accessed are
+stored on another member the I/O will be forwarded as required.  This
+forwarding is invisible to the initiator.  The storage layout is also
+dynamic, and the blocks stored on disk may be moved from member to
+member as needed to balance the load.
+
+This architecture simplifies the management and configuration of both
+the storage group and initiators.  In a multipathing configuration, it
+is possible to set up multiple iSCSI sessions to use multiple network
+interfaces on both the host and target to take advantage of the
+increased network bandwidth.  An initiator could use a simple round
+robin algorithm to send I/O across all paths and let the storage array
+members forward it as necessary, but there is a performance advantage to
+sending data directly to the correct member.
+
+A device-mapper table already lets you map different regions of a
+device onto different targets.  However in this architecture the LUN is
+spread with an address region size on the order of 10s of MBs, which
+means the resulting table could have more than a million entries and
+consume far too much memory.
+
+Using this device-mapper switch target we can now build a two-layer
+device hierarchy:
+
+    Upper Tier – Determine which array member the I/O should be sent to.
+    Lower Tier – Load balance amongst paths to a particular member.
+
+The lower tier consists of a single dm multipath device for each member.
+Each of these multipath devices contains the set of paths directly to
+the array member in one priority group, and leverages existing path
+selectors to load balance amongst these paths.  We also build a
+non-preferred priority group containing paths to other array members for
+failover reasons.
+
+The upper tier consists of a single dm-switch device.  This device uses
+a bitmap to look up the location of the I/O and choose the appropriate
+lower tier device to route the I/O.  By using a bitmap we are able to
+use 4 bits for each address range in a 16 member group (which is very
+large for us).  This is a much denser representation than the dm table
+b-tree can achieve.
+
+Construction Parameters
+=======================
+
+    <num_paths> <region_size> <num_optional_args> [<optional_args>...]
+    [<dev_path> <offset>]+
+
+<num_paths>
+    The number of paths across which to distribute the I/O.
+
+<region_size>
+    The number of 512-byte sectors in a region. Each region can be redirected
+    to any of the available paths.
+
+<num_optional_args>
+    The number of optional arguments. Currently, no optional arguments
+    are supported and so this must be zero.
+
+<dev_path>
+    The block device that represents a specific path to the device.
+
+<offset>
+    The offset of the start of data on the specific <dev_path> (in units
+    of 512-byte sectors). This number is added to the sector number when
+    forwarding the request to the specific path. Typically it is zero.
+
+Messages
+========
+
+set_region_mappings <index>:<path_nr> [<index>]:<path_nr> [<index>]:<path_nr>...
+
+Modify the region table by specifying which regions are redirected to
+which paths.
+
+<index>
+    The region number (region size was specified in constructor parameters).
+    If index is omitted, the next region (previous index + 1) is used.
+    Expressed in hexadecimal (WITHOUT any prefix like 0x).
+
+<path_nr>
+    The path number in the range 0 ... (<num_paths> - 1).
+    Expressed in hexadecimal (WITHOUT any prefix like 0x).
+
+Status
+======
+
+No status line is reported.
+
+Example
+=======
+
+Assume that you have volumes vg1/switch0 vg1/switch1 vg1/switch2 with
+the same size.
+
+Create a switch device with 64kB region size:
+    dmsetup create switch --table "0 `blockdev --getsize /dev/vg1/switch0`
+	switch 3 128 0 /dev/vg1/switch0 0 /dev/vg1/switch1 0 /dev/vg1/switch2 0"
+
+Set mappings for the first 7 entries to point to devices switch0, switch1,
+switch2, switch0, switch1, switch2, switch1:
+    dmsetup message switch 0 set_region_mappings 0:0 :1 :2 :0 :1 :2 :1

+- reg : Should contain DMA registers location and length
+- interrupts : First item should be DMA interrupt, second one is optional and

+- #dma-cells : Has to be 1. imx-dma does not support anything else.
+
+Optional properties:
+- #dma-channels : Number of DMA channels supported. Should be 16.
+- #dma-requests : Number of DMA requests supported.

+* DMA client
+
+Clients have to specify the DMA requests with phandles in a list.
+
+Required properties:
+- dmas: List of one or more DMA request specifiers. One DMA request specifier
+    consists of a phandle to the DMA controller followed by the integer
+    specifiying the request line.
+- dma-names: List of string identifiers for the DMA requests. For the correct
+    names, have a look at the specific client driver.
+
+Example:
+
+	sdhci1: sdhci@10013000 {

+* SHDMA Device Tree bindings
+
+Sh-/r-mobile and r-car systems often have multiple identical DMA controller
+instances, capable of serving any of a common set of DMA slave devices, using
+the same configuration. To describe this topology we require all compatible
+SHDMA DT nodes to be placed under a DMA multiplexer node. All such compatible
+DMAC instances have the same number of channels and use the same DMA
+descriptors. Therefore respective DMA DT bindings can also all be placed in the
+multiplexer node. Even if there is only one such DMAC instance on a system, it
+still has to be placed under such a multiplexer node.

+Required properties:
+- compatible:	should be "renesas,shdma-mux"

+Xilinx plb/axi GPIO controller
+
+Dual channel GPIO controller with configurable number of pins
+(from 1 to 32 per channel). Every pin can be configured as
+input/output/tristate. Both channels share the same global IRQ but
+local interrupts can be enabled on channel basis.
+
+Required properties:
+- compatible : Should be "xlnx,xps-gpio-1.00.a"
+- reg : Address and length of the register set for the device
+- #gpio-cells : Should be two. The first cell is the pin number and the
+  second cell is used to specify optional parameters (currently unused).
+- gpio-controller : Marks the device node as a GPIO controller.
+
+Optional properties:
+- interrupts : Interrupt mapping for GPIO IRQ.
+- interrupt-parent : Phandle for the interrupt controller that
+  services interrupts for this device.
+- xlnx,all-inputs : if n-th bit is setup, GPIO-n is input
+- xlnx,dout-default : if n-th bit is 1, GPIO-n default value is 1
+- xlnx,gpio-width : gpio width
+- xlnx,tri-default : if n-th bit is 1, GPIO-n is in tristate mode
+- xlnx,is-dual : if 1, controller also uses the second channel
+- xlnx,all-inputs-2 : as above but for the second channel
+- xlnx,dout-default-2 : as above but the second channel
+- xlnx,gpio2-width : as above but for the second channel
+- xlnx,tri-default-2 : as above but for the second channel

+* TI - TSC ADC (Touschscreen and analog digital converter)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+Required properties:
+- child "tsc"
+	ti,wires: Wires refer to application modes i.e. 4/5/8 wire touchscreen
+		  support on the platform.
+	ti,x-plate-resistance: X plate resistance
+	ti,coordiante-readouts: The sequencer supports a total of 16
+				programmable steps each step is used to
+				read a single coordinate. A single
+                                readout is enough but multiple reads can
+				increase the quality.
+				A value of 5 means, 5 reads for X, 5 for
+				Y and 2 for Z (always). This utilises 12
+				of the 16 software steps available. The
+				remaining 4 can be used by the ADC.
+	ti,wire-config: Different boards could have a different order for
+			connecting wires on touchscreen. We need to provide an
+			8 bit number where in the 1st four bits represent the
+			analog lines and the next 4 bits represent positive/
+			negative terminal on that input line. Notations to
+			represent the input lines and terminals resoectively
+			is as follows:
+			AIN0 = 0, AIN1 = 1 and so on till AIN7 = 7.
+			XP  = 0, XN = 1, YP = 2, YN = 3.

+* ARM System MMU Architecture Implementation
+
+ARM SoCs may contain an implementation of the ARM System Memory
+Management Unit Architecture, which can be used to provide 1 or 2 stages
+of address translation to bus masters external to the CPU.
+
+The SMMU may also raise interrupts in response to various fault
+conditions.
+
+** System MMU required properties:
+
+- compatible    : Should be one of:
+
+                        "arm,smmu-v1"
+                        "arm,smmu-v2"
+                        "arm,mmu-400"
+                        "arm,mmu-500"
+
+                  depending on the particular implementation and/or the
+                  version of the architecture implemented.
+
+- reg           : Base address and size of the SMMU.
+
+- #global-interrupts : The number of global interrupts exposed by the
+                       device.
+
+- interrupts    : Interrupt list, with the first #global-irqs entries
+                  corresponding to the global interrupts and any
+                  following entries corresponding to context interrupts,
+                  specified in order of their indexing by the SMMU.
+
+                  For SMMUv2 implementations, there must be exactly one
+                  interrupt per context bank. In the case of a single,
+                  combined interrupt, it must be listed multiple times.
+
+- mmu-masters   : A list of phandles to device nodes representing bus
+                  masters for which the SMMU can provide a translation
+                  and their corresponding StreamIDs (see example below).
+                  Each device node linked from this list must have a
+                  "#stream-id-cells" property, indicating the number of
+                  StreamIDs associated with it.
+
+** System MMU optional properties:
+
+- smmu-parent   : When multiple SMMUs are chained together, this
+                  property can be used to provide a phandle to the
+                  parent SMMU (that is the next SMMU on the path going
+                  from the mmu-masters towards memory) node for this
+                  SMMU.
+

+* Maxim MAX8998, National/TI LP3974 multi-function device
+
+The Maxim MAX8998 is a multi-function device which includes voltage/current
+regulators, real time clock, battery charging controller and several
+other sub-blocks. It is interfaced using an I2C interface. Each sub-block
+is addressed by the host system using different i2c slave address.
+
+PMIC sub-block
+--------------
+
+The PMIC sub-block contains a number of voltage and current regulators,
+with controllable parameters and dynamic voltage scaling capability.
+In addition, it includes a real time clock and battery charging controller
+as well. It is accessible at I2C address 0x66.
+
+Required properties:
+- compatible: Should be one of the following:
+    - "maxim,max8998" for Maxim MAX8998
+    - "national,lp3974" or "ti,lp3974" for National/TI LP3974.
+- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
+
+Optional properties:
+- interrupt-parent: Specifies the phandle of the interrupt controller to which
+  the interrupts from MAX8998 are routed to.
+- interrupts: Interrupt specifiers for two interrupt sources.
+  - First interrupt specifier is for main interrupt.
+  - Second interrupt specifier is for power-on/-off interrupt.
+- max8998,pmic-buck1-dvs-gpios: GPIO specifiers for two host gpios used
+  for buck 1 dvs. The format of the gpio specifier depends on the gpio
+  controller.
+- max8998,pmic-buck2-dvs-gpio: GPIO specifier for host gpio used
+  for buck 2 dvs. The format of the gpio specifier depends on the gpio
+  controller.
+- max8998,pmic-buck1-default-dvs-idx: Default voltage setting selected from
+  the possible 4 options selectable by the dvs gpios. The value of this
+  property should be 0, 1, 2 or 3. If not specified or out of range,
+  a default value of 0 is taken.
+- max8998,pmic-buck2-default-dvs-idx: Default voltage setting selected from
+  the possible 2 options selectable by the dvs gpios. The value of this
+  property should be 0 or 1. If not specified or out of range, a default
+  value of 0 is taken.
+- max8998,pmic-buck-voltage-lock: If present, disallows changing of
+  preprogrammed buck dvfs voltages.
+
+Additional properties required if max8998,pmic-buck1-dvs-gpios is defined:
+- max8998,pmic-buck1-dvs-voltage: An array of 4 voltage values in microvolts
+  for buck1 regulator that can be selected using dvs gpio.
+
+Additional properties required if max8998,pmic-buck2-dvs-gpio is defined:
+- max8998,pmic-buck2-dvs-voltage: An array of 2 voltage values in microvolts
+  for buck2 regulator that can be selected using dvs gpio.
+
+Regulators: All the regulators of MAX8998 to be instantiated shall be
+listed in a child node named 'regulators'. Each regulator is represented
+by a child node of the 'regulators' node.
+
+	regulator-name {
+		/* standard regulator bindings here */
+	};
+
+Following regulators of the MAX8998 PMIC block are supported. Note that
+the 'n' in regulator name, as in LDOn or BUCKn, represents the LDO or BUCK
+number as described in MAX8998 datasheet.
+
+	- LDOn
+		  - valid values for n are 2 to 17
+		  - Example: LDO2, LDO10, LDO17
+	- BUCKn
+		  - valid values for n are 1 to 4.
+		  - Example: BUCK1, BUCK2, BUCK3, BUCK4
+
+	- ENVICHG: Battery Charging Current Monitor Output. This is a fixed
+		   voltage type regulator
+
+	- ESAFEOUT1: (ldo19)
+	- ESAFEOUT2: (ld020)
+
+Standard regulator bindings are used inside regulator subnodes. Check
+  Documentation/devicetree/bindings/regulator/regulator.txt

+The Marvell Discovery ethernet controller can be found on Marvell Orion SoCs
+(Kirkwood, Dove, Orion5x, and Discovery Innovation) and as part of Marvell
+Discovery system controller chips (mv64[345]60).
+
+The Discovery ethernet controller is described with two levels of nodes. The
+first level describes the ethernet controller itself and the second level
+describes up to 3 ethernet port nodes within that controller. The reason for
+the multiple levels is that the port registers are interleaved within a single
+set of controller registers. Each port node describes port-specific properties.
+
+Note: The above separation is only true for Discovery system controllers.
+For Orion SoCs we stick to the separation, although there each controller has
+only one port associated. Multiple ports are implemented as multiple single-port
+controllers. As Kirkwood has some issues with proper initialization after reset,
+an extra compatible string is added for it.

+ImgTec TZ1090 PDC pin controller
+
+Required properties:
+- compatible: "img,tz1090-pdc-pinctrl"
+- reg: Should contain the register physical address and length of the
+  SOC_GPIO_CONTROL registers in the PDC register region.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+TZ1090-PDC's pin configuration nodes act as a container for an abitrary number
+of subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function. For this reason, even seemingly boolean
+values are actually tristates in this binding: unspecified, off, or on.
+Unspecified is represented as an absent property, and off/on are represented as
+integer values 0 and 1.
+
+Required subnode-properties:
+- tz1090,pins : An array of strings. Each string contains the name of a pin or
+  group. Valid values for these names are listed below.
+
+Optional subnode-properties:
+- tz1090,function: A string containing the name of the function to mux to the
+  pin or group. Valid values for function names are listed below, including
+  which pingroups can be muxed to them.
+- supported generic pinconfig properties (for further details see
+  Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt):
+  - bias-disable
+  - bias-high-impedance
+  - bias-bus-hold
+  - bias-pull-up
+  - bias-pull-down
+  - input-schmitt-enable
+  - input-schmitt-disable
+  - drive-strength: Integer, control drive strength of pins in mA.
+      2: 2mA
+      4: 4mA
+      8: 8mA
+      12: 12mA
+  - low-power-enable: Flag, power-on-start weak pull-down for invalid power.
+  - low-power-disable: Flag, power-on-start weak pull-down disabled.
+
+Note that many of these properties are only valid for certain specific pins
+or groups. See the TZ1090 TRM for complete details regarding which groups
+support which functionality. The Linux pinctrl driver may also be a useful
+reference.
+
+Valid values for pin and group names are:
+
+  pins:
+
+    These all support bias-high-impediance, bias-pull-up, bias-pull-down, and
+    bias-bus-hold (which can also be provided to any of the groups below to set
+    it for all gpio pins in that group).
+
+    gpio0, gpio1, sys_wake0, sys_wake1, sys_wake2, ir_data, ext_power.
+
+  mux groups:
+
+    These all support function.
+
+    gpio0
+        pins:       gpio0.
+        function:   ir_mod_stable_out.
+    gpio1
+        pins:       gpio1.
+        function:   ir_mod_power_out.
+
+  drive groups:
+
+    These support input-schmitt-enable, input-schmitt-disable,
+    drive-strength, low-power-enable, and low-power-disable.

+        pins:   gpio0, gpio1, sys_wake0, sys_wake1, sys_wake2, ir_data,
+                ext_power.
+

+
+	pinctrl_pdc: pinctrl@02006500 {
+		#gpio-range-cells = <3>;
+		compatible = "img,tz1090-pdc-pinctrl";

+
+pcfg_pull_up: pcfg_pull_up {

+*ST pin controller.
+
+Each multi-function pin is controlled, driven and routed through the
+PIO multiplexing block. Each pin supports GPIO functionality (ALT0)
+and multiple alternate functions(ALT1 - ALTx) that directly connect
+the pin to different hardware blocks.
+
+When a pin is in GPIO mode, Output Enable (OE), Open Drain(OD), and
+Pull Up (PU) are driven by the related PIO block.
+
+ST pinctrl driver controls PIO multiplexing block and also interacts with

+- #gpio-cells	  : Should be one. The first cell is the pin number.
+- st,retime-pin-mask	: Should be mask to specify which pins can be retimed.

+* Renesas Pin Function Controller (GPIO and Pin Mux/Config)
+
+The Pin Function Controller (PFC) is a Pin Mux/Config controller. On SH7372,
+SH73A0, R8A73A4 and R8A7740 it also acts as a GPIO controller.
+
+
+Pin Control
+-----------
+
+Required Properties:
+
+  - compatible: should be one of the following.
+    - "renesas,pfc-r8a73a4": for R8A73A4 (R-Mobile APE6) compatible pin-controller.
+    - "renesas,pfc-r8a7740": for R8A7740 (R-Mobile A1) compatible pin-controller.
+    - "renesas,pfc-r8a7778": for R8A7778 (R-Mobile M1) compatible pin-controller.
+    - "renesas,pfc-r8a7779": for R8A7779 (R-Car H1) compatible pin-controller.
+    - "renesas,pfc-r8a7790": for R8A7790 (R-Car H2) compatible pin-controller.
+    - "renesas,pfc-sh7372": for SH7372 (SH-Mobile AP4) compatible pin-controller.
+    - "renesas,pfc-sh73a0": for SH73A0 (SH-Mobile AG5) compatible pin-controller.
+
+  - reg: Base address and length of each memory resource used by the pin
+    controller hardware module.
+
+Optional properties:
+
+  - #gpio-range-cells: Mandatory when the PFC doesn't handle GPIO, forbidden
+    otherwise. Should be 3.
+
+The PFC node also acts as a container for pin configuration nodes. Please refer
+to pinctrl-bindings.txt in this directory for the definition of the term "pin
+configuration node" and for the common pinctrl bindings used by client devices.
+
+Each pin configuration node represents a desired configuration for a pin, a
+pin group, or a list of pins or pin groups. The configuration can include the
+function to select on those pin(s) and pin configuration parameters (such as
+pull-up and pull-down).
+
+Pin configuration nodes contain pin configuration properties, either directly
+or grouped in child subnodes. Both pin muxing and configuration parameters can
+be grouped in that way and referenced as a single pin configuration node by
+client devices.
+
+A configuration node or subnode must reference at least one pin (through the
+pins or pin groups properties) and contain at least a function or one
+configuration parameter. When the function is present only pin groups can be
+used to reference pins.
+
+All pin configuration nodes and subnodes names are ignored. All of those nodes
+are parsed through phandles and processed purely based on their content.
+
+Pin Configuration Node Properties:
+
+- renesas,pins : An array of strings, each string containing the name of a pin.
+- renesas,groups : An array of strings, each string containing the name of a pin
+  group.
+
+- renesas,function: A string containing the name of the function to mux to the
+  pin group(s) specified by the renesas,groups property
+
+  Valid values for pin, group and function names can be found in the group and
+  function arrays of the PFC data file corresponding to the SoC
+  (drivers/pinctrl/sh-pfc/pfc-*.c)
+
+The pin configuration parameters use the generic pinconf bindings defined in
+pinctrl-bindings.txt in this directory. The supported parameters are
+bias-disable, bias-pull-up and bias-pull-down.
+
+
+GPIO
+----
+
+On SH7372, SH73A0, R8A73A4 and R8A7740 the PFC node is also a GPIO controller
+node.
+
+Required Properties:
+
+  - gpio-controller: Marks the device node as a gpio controller.
+
+  - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
+    cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
+    GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
+
+The syntax of the gpio specifier used by client nodes should be the following
+with values derived from the SoC user manual.
+
+  <[phandle of the gpio controller node]
+   [pin number within the gpio controller]
+   [flags]>
+
+On other mach-shmobile platforms GPIO is handled by the gpio-rcar driver.
+Please refer to Documentation/devicetree/bindings/gpio/renesas,gpio-rcar.txt
+for documentation of the GPIO device tree bindings on those platforms.
+

+* Rockchip Pinmux Controller
+
+The Rockchip Pinmux Controller, enables the IC
+to share one PAD to several functional blocks. The sharing is done by
+multiplexing the PAD input/output signals. For each PAD there are up to
+4 muxing options with option 0 being the use as a GPIO.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The Rockchip pin configuration node is a node of a group of pins which can be
+used for a specific device or function. This node represents both mux and
+config of the pins in that group. The 'pins' selects the function mode(also
+named pin mode) this pin can work on and the 'config' configures various pad
+settings such as pull-up, etc.
+
+The pins are grouped into up to 5 individual pin banks which need to be
+defined as gpio sub-nodes of the pinmux controller.
+
+Required properties for iomux controller:
+  - compatible: one of "rockchip,rk2928-pinctrl", "rockchip,rk3066a-pinctrl"
+		       "rockchip,rk3066b-pinctrl", "rockchip,rk3188-pinctrl"
+
+Required properties for gpio sub nodes:

+  - reg: register of the gpio bank (different than the iomux registerset)
+  - interrupts: base interrupt of the gpio bank in the interrupt controller
+  - clocks: clock that drives this bank
+  - gpio-controller: identifies the node as a gpio controller and pin bank.
+  - #gpio-cells: number of cells in GPIO specifier. Since the generic GPIO
+    binding is used, the amount of cells must be specified as 2. See generic
+    GPIO binding documentation for description of particular cells.
+  - interrupt-controller: identifies the controller node as interrupt-parent.
+  - #interrupt-cells: the value of this property should be 2 and the interrupt
+    cells should use the standard two-cell scheme described in
+    bindings/interrupt-controller/interrupts.txt
+
+Required properties for pin configuration node:
+  - rockchip,pins: 3 integers array, represents a group of pins mux and config
+    setting. The format is rockchip,pins = <PIN_BANK PIN_BANK_IDX MUX &phandle>.
+    The MUX 0 means gpio and MUX 1 to 3 mean the specific device function.

+ST Ericsson abx500 pinmux controller
+
+Required properties:

+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+ST Ericsson's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as input, output, pull up, pull down...
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Required subnode-properties:
+- ste,pins : An array of strings. Each string contains the name of a pin or
+    group.
+
+Optional subnode-properties:
+- ste,function: A string containing the name of the function to mux to the
+  pin or group.
+
+- generic pin configuration option to use. Example :
+
+	default_cfg {
+		ste,pins = "GPIO1";
+		bias-disable;
+	};
+
+- ste,config: Handle of pin configuration node containing the generic
+  pinconfig options to use, as described in pinctrl-bindings.txt in
+  this directory. Example :
+
+	pcfg_bias_disable: pcfg_bias_disable {
+		bias-disable;
+	};
+
+	default_cfg {
+		ste,pins = "GPIO1";

+Interlaken Look-Aside Controller (LAC) Node
+
+DESCRIPTION
+
+The Interlaken is a narrow, high speed channelized chip-to-chip interface. To
+facilitate interoperability between a data path device and a look-aside
+co-processor, the Interlaken Look-Aside protocol is defined for short
+transaction-related transfers. Although based on the Interlaken protocol,
+Interlaken Look-Aside is not directly compatible with Interlaken and can be
+considered a different operation mode.
+
+The Interlaken LA controller connects internal platform to Interlaken serial
+interface. It accepts LA command through software portals, which are system
+memory mapped 4KB spaces. The LA commands are then translated into the
+Interlaken control words and data words, which are sent on TX side to TCAM
+through SerDes lanes.
+
+There are two 4KiB spaces defined within the LAC global register memory map.
+There is a full register set at 0x0000-0x0FFF (also known as the "hypervisor"
+version), and a subset at 0x1000-0x1FFF.  The former is a superset of the
+latter, and includes certain registers that should not be accessible to
+partitioned software.  Separate nodes are used for each region, with a phandle
+linking the hypervisor node to the normal operating node.
+
+PROPERTIES
+
+  - compatible
+	Usage: required
+	Value type: <string>

+	Each item consists of the following in the same order:
+	volt: voltage in uV - Only used to index ABB information.
+	ABB mode: one of the following:
+		0-bypass
+		1-Forward Body Bias(FBB)
+		3-Reverse Body Bias(RBB)
+	efuse:	(see Optional properties)
+	RBB enable efuse Mask:	(See Optional properties)
+	FBB enable efuse Mask:	(See Optional properties)
+	Vset value efuse Mask:	(See Optional properties)
+
+	NOTE: If more than 1 entry is present, then regulator is setup to change
+	      voltage, allowing for various modes to be selected indexed off
+	      the regulator. Further, ABB LDOs are considered always-on by
+	      default.
+
+Optional Properties:
+- reg-names: In addition to the required properties, the following are optional
+  - "efuse-address"	- Contains efuse base address used to pick up ABB info.
+  - "ldo-address"	- Contains address of ABB LDO overide register address.
+	"efuse-address" is required for this.
+- ti,ldovbb-vset-mask	- Required if ldo-address is set, mask for LDO override
+	register to provide override vset value.
+- ti,ldovbb-override-mask - Required if ldo-address is set, mask for LDO
+	override register to enable override vset value.
+- ti,abb_opp_sel: Addendum to the description in required properties
+	efuse: Mandatory if 'efuse-address' register is defined. Provides offset
+	       from efuse-address to pick up ABB characteristics. Set to 0 if
+	       'efuse-address' is not defined.
+	RBB enable efuse Mask:	Optional if 'efuse-address' register is defined.
+		'ABB mode' is force set to RBB mode if value at "efuse-address"
+		+ efuse maps to RBB mask. Set to 0 to ignore this.
+	FBB enable efuse Mask:	Optional if 'efuse-address' register is defined.
+		'ABB mode' is force set to FBB mode if value at "efuse-address"
+		+ efuse maps to FBB mask (valid only if RBB mask does not match)
+		Set to 0 to ignore this.
+	Vset value efuse Mask:	Mandatory if ldo-address is set. Picks up from
+		efuse the value to set in 'ti,ldovbb-vset-mask' at ldo-address.
+
+Example #1: Simplest configuration (no efuse data, hard coded ABB table):
+abb_x: regulator-abb-x {

+* Texas Instrument OMAP SCM bandgap bindings
+
+In the System Control Module, OMAP supplies a voltage reference
+and a temperature sensor feature that are gathered in the band
+gap voltage and temperature sensor (VBGAPTS) module. The band
+gap provides current and voltage reference for its internal
+circuits and other analog IP blocks. The analog-to-digital
+converter (ADC) produces an output value that is proportional
+to the silicon temperature.
+
+Required properties:
+- compatible : Should be:
+  - "ti,omap4430-bandgap" : for OMAP4430 bandgap
+  - "ti,omap4460-bandgap" : for OMAP4460 bandgap
+  - "ti,omap4470-bandgap" : for OMAP4470 bandgap
+  - "ti,omap5430-bandgap" : for OMAP5430 bandgap
+- interrupts : this entry should indicate which interrupt line
+the talert signal is routed to;
+Specific:
+- gpios : this entry should be used to inform which GPIO
+line the tshut signal is routed to. The informed GPIO will
+be treated as an IRQ;
+- regs : this entry must also be specified and it is specific
+to each bandgap version, because the mapping may change from
+soc to soc, apart of depending on available features.
+
+Example:
+OMAP4430:
+bandgap {
+	reg = <0x4a002260 0x4 0x4a00232C 0x4>;

-	These options define what group ID a newly created file gets.
-	When grpid is set, it takes the group ID of the directory in

-Temperature conversion of the DS1621 takes up to 1000ms; internal access to
-non-volatile registers may last for 10ms or below.
+Since there is no version or vendor identification register, there is
+no unique identification for these devices. Therefore, explicit device
+instantiation is required for correct device identification and functionality
+(one device per address in this address range: 0x48..0x4f).
+
+The DS1625 is pin compatible and functionally equivalent with the DS1621,
+but the DS1621 is meant to replace it. The DS1631, DS1721, and DS1731 are
+also pin compatible with the DS1621 and provide multi-resolution support.
+
+Additionally, the DS1721 data sheet says the temperature flags (THF and TLF)
+are used internally, however, these flags do get set and cleared as the actual
+temperature crosses the min or max settings (which by default are set to 75
+and 80 degrees respectively).
+
+Temperature Conversion:
+-----------------------
+DS1621 - 750ms (older devices may take up to 1000ms)
+DS1625 - 500ms
+DS1631 - 93ms..750ms for 9..12 bits resolution, respectively.
+DS1721 - 93ms..750ms for 9..12 bits resolution, respectively.
+DS1731 - 93ms..750ms for 9..12 bits resolution, respectively.
+
+Note:
+On the DS1621, internal access to non-volatile registers may last for 10ms
+or less (unverified on the other devices).
+
+Temperature Accuracy:
+---------------------
+DS1621: +/- 0.5 degree Celsius (from 0 to +70 degrees)
+DS1625: +/- 0.5 degree Celsius (from 0 to +70 degrees)
+DS1631: +/- 0.5 degree Celsius (from 0 to +70 degrees)
+DS1721: +/- 1.0 degree Celsius (from -10 to +85 degrees)
+DS1731: +/- 1.0 degree Celsius (from -10 to +85 degrees)
+
+Note:
+Please refer to the device datasheets for accuracy at other temperatures.
+
+Temperature Resolution:
+-----------------------
+As mentioned above, the DS1631, DS1721, and DS1731 provide multi-resolution
+support, which is achieved via the R0 and R1 config register bits, where:
+
+R0..R1
+------
+ 0  0 => 9 bits, 0.5 degrees Celcius
+ 1  0 => 10 bits, 0.25 degrees Celcius
+ 0  1 => 11 bits, 0.125 degrees Celcius
+ 1  1 => 12 bits, 0.0625 degrees Celcius
+
+Note:
+At initial device power-on, the default resolution is set to 12-bits.
+
+The resolution mode for the DS1631, DS1721, or DS1731 can be changed from
+userspace, via the device 'update_interval' sysfs attribute. This attribute
+will normalize the range of input values to the device maximum resolution
+values defined in the datasheet as follows:
+
+Resolution    Conversion Time    Input Range
+ (C/LSB)       (msec)             (msec)
+------------------------------------------------
+0.5             93.75              0....94
+0.25            187.5              95...187
+0.125           375                188..375
+0.0625          750                376..infinity
+------------------------------------------------
+
+The following examples show how the 'update_interval' attribute can be
+used to change the conversion time:
+
+$ cat update_interval
+750
+$ cat temp1_input
+22062
+$
+$ echo 300 > update_interval
+$ cat update_interval
+375
+$ cat temp1_input
+22125
+$
+$ echo 150 > update_interval
+$ cat update_interval
+188
+$ cat temp1_input
+22250
+$
+$ echo 1 > update_interval
+$ cat update_interval
+94
+$ cat temp1_input
+22000
+$
+$ echo 1000 > update_interval
+$ cat update_interval
+750
+$ cat temp1_input
+22062
+$
+
+As shown, the ds1621 driver automatically adjusts the 'update_interval'
+user input, via a step function. Reading back the 'update_interval' value
+after a write operation provides the conversion time used by the device.
+
+Mathematically, the resolution can be derived from the conversion time
+via the following function:
+
+   g(x) = 0.5 * [minimum_conversion_time/x]
+
+where:
+ -> 'x' = the output from 'update_interval'
+ -> 'g(x)' = the resolution in degrees C per LSB.
+ -> 93.75ms = minimum conversion time

+Kernel driver g762
+==================
+
+The GMT G762 Fan Speed PWM Controller is connected directly to a fan
+and performs closed-loop or open-loop control of the fan speed. Two
+modes - PWM or DC - are supported by the device.
+
+For additional information, a detailed datasheet is available at
+http://natisbad.org/NAS/ref/GMT_EDS-762_763-080710-0.2.pdf. sysfs
+bindings are described in Documentation/hwmon/sysfs-interface.
+
+The following entries are available to the user in a subdirectory of
+/sys/bus/i2c/drivers/g762/ to control the operation of the device.
+This can be done manually using the following entries but is usually
+done via a userland daemon like fancontrol.
+
+Note that those entries do not provide ways to setup the specific
+hardware characteristics of the system (reference clock, pulses per
+fan revolution, ...); Those can be modified via devicetree bindings
+documented in Documentation/devicetree/bindings/hwmon/g762.txt or
+using a specific platform_data structure in board initialization
+file (see include/linux/platform_data/g762.h).
+
+  fan1_target: set desired fan speed. This only makes sense in closed-loop
+            fan speed control (i.e. when pwm1_enable is set to 2).
+
+  fan1_input: provide current fan rotation value in RPM as reported by
+            the fan to the device.
+
+  fan1_div: fan clock divisor. Supported value are 1, 2, 4 and 8.
+
+  fan1_pulses: number of pulses per fan revolution. Supported values
+            are 2 and 4.
+
+  fan1_fault: reports fan failure, i.e. no transition on fan gear pin for
+            about 0.7s (if the fan is not voluntarily set off).
+
+  fan1_alarm: in closed-loop control mode, if fan RPM value is 25% out
+            of the programmed value for over 6 seconds 'fan1_alarm' is
+            set to 1.
+
+  pwm1_enable: set current fan speed control mode i.e. 1 for manual fan
+            speed control (open-loop) via pwm1 described below, 2 for
+            automatic fan speed control (closed-loop) via fan1_target
+            above.
+
+  pwm1_mode: set or get fan driving mode: 1 for PWM mode, 0 for DC mode.
+
+  pwm1: get or set PWM fan control value in open-loop mode. This is an
+            integer value between 0 and 255. 0 stops the fan, 255 makes
+            it run at full speed.
+
+Both in PWM mode ('pwm1_mode' set to 1) and DC mode ('pwm1_mode' set to 0),
+when current fan speed control mode is open-loop ('pwm1_enable' set to 1),
+the fan speed is programmed by setting a value between 0 and 255 via 'pwm1'
+entry (0 stops the fan, 255 makes it run at full speed). In closed-loop mode
+('pwm1_enable' set to 2), the expected rotation speed in RPM can be passed to
+the chip via 'fan1_target'. In closed-loop mode, the target speed is compared
+with current speed (available via 'fan1_input') by the device and a feedback
+is performed to match that target value. The fan speed value is computed
+based on the parameters associated with the physical characteristics of the
+system: a reference clock source frequency, a number of pulses per fan
+revolution, etc.
+
+Note that the driver will update its values at most once per second.

-	The ifenslave user level control program is included in the

-that is newer than the kernel is not supported, and may or may not
-work.
-
-	To install ifenslave, do the following:
-
-# gcc -Wall -O -I/usr/src/linux/include ifenslave.c -o ifenslave
-# cp ifenslave /sbin/ifenslave
-
-	If your kernel source is not in "/usr/src/linux," then replace
-"/usr/src/linux/include" in the above with the location of your kernel
-source include directory.
-
-	You may wish to back up any existing /sbin/ifenslave, or, for
-testing or informal use, tag the ifenslave to the kernel version
-(e.g., name the ifenslave executable /sbin/ifenslave-2.6.10).
-
-IMPORTANT NOTE:
-
-	If you omit the "-I" or specify an incorrect directory, you
-may end up with an ifenslave that is incompatible with the kernel
-you're trying to build it for.  Some distros (e.g., Red Hat from 7.1
-onwards) do not have /usr/include/linux symbolically linked to the
-default kernel source include directory.

-SECOND IMPORTANT NOTE:
-	If you plan to configure bonding using sysfs or using the
-/etc/network/interfaces file, you do not need to use ifenslave.

- *         the first device when not previously set ;
- *       - detach support : call BOND_RELEASE to detach an enslaved interface.
- *       - give a mini-howto from command-line help : # ifenslave -h
- *
- *    - 2001/02/16 Chad N. Tindel <ctindel at ieee dot org> :
- *       - Master is now brought down before setting the MAC address.  In
- *         the 2.4 kernel you can't change the MAC address while the device is
- *         up because you get EBUSY.
- *
- *    - 2001/09/13 Takao Indoh <indou dot takao at jp dot fujitsu dot com>
- *       - Added the ability to change the active interface on a mode 1 bond
- *         at runtime.
- *
- *    - 2001/10/23 Chad N. Tindel <ctindel at ieee dot org> :
- *       - No longer set the MAC address of the master.  The bond device will
- *         take care of this itself
- *       - Try the SIOC*** versions of the bonding ioctls before using the
- *         old versions
- *    - 2002/02/18 Erik Habbinga <erik_habbinga @ hp dot com> :
- *       - ifr2.ifr_flags was not initialized in the hwaddr_notset case,
- *         SIOCGIFFLAGS now called before hwaddr_notset test
- *
- *    - 2002/10/31 Tony Cureington <tony.cureington * hp_com> :
- *       - If the master does not have a hardware address when the first slave
- *         is enslaved, the master is assigned the hardware address of that
- *         slave - there is a comment in bonding.c stating "ifenslave takes
- *         care of this now." This corrects the problem of slaves having
- *         different hardware addresses in active-backup mode when
- *         multiple interfaces are specified on a single ifenslave command
- *         (ifenslave bond0 eth0 eth1).

- *                   Shmulik Hen <shmulik.hen at intel dot com>
- *       - Moved setting the slave's mac address and openning it, from
- *         the application to the driver. This enables support of modes
- *         that need to use the unique mac address of each slave.
- *         The driver also takes care of closing the slave and restoring its
- *         original mac address upon release.
- *         In addition, block possibility of enslaving before the master is up.
- *         This prevents putting the system in an undefined state.
- *
- *    - 2003/05/01 - Amir Noam <amir.noam at intel dot com>
- *       - Added ABI version control to restore compatibility between
- *         new/old ifenslave and new/old bonding.
- *       - Prevent adding an adapter that is already a slave.

 RPS might be beneficial if the rps_cpus for each queue are the ones that
 share the same memory domain as the interrupting CPU for that queue.
 
+==== RPS Flow Limit
+
+RPS scales kernel receive processing across CPUs without introducing
+reordering. The trade-off to sending all packets from the same flow
+to the same CPU is CPU load imbalance if flows vary in packet rate.
+In the extreme case a single flow dominates traffic. Especially on
+common server workloads with many concurrent connections, such
+behavior indicates a problem such as a misconfiguration or spoofed
+source Denial of Service attack.
+
+Flow Limit is an optional RPS feature that prioritizes small flows
+during CPU contention by dropping packets from large flows slightly
+ahead of those from small flows. It is active only when an RPS or RFS
+destination CPU approaches saturation.  Once a CPU's input packet
+queue exceeds half the maximum queue length (as set by sysctl
+net.core.netdev_max_backlog), the kernel starts a per-flow packet
+count over the last 256 packets. If a flow exceeds a set ratio (by
+default, half) of these packets when a new packet arrives, then the
+new packet is dropped. Packets from other flows are still only
+dropped once the input packet queue reaches netdev_max_backlog.
+No packets are dropped when the input packet queue length is below
+the threshold, so flow limit does not sever connections outright:
+even large flows maintain connectivity.
+
+== Interface
+
+Flow limit is compiled in by default (CONFIG_NET_FLOW_LIMIT), but not
+turned on. It is implemented for each CPU independently (to avoid lock
+and cache contention) and toggled per CPU by setting the relevant bit
+in sysctl net.core.flow_limit_cpu_bitmap. It exposes the same CPU
+bitmap interface as rps_cpus (see above) when called from procfs:
+
+ /proc/sys/net/core/flow_limit_cpu_bitmap
+
+Per-flow rate is calculated by hashing each packet into a hashtable
+bucket and incrementing a per-bucket counter. The hash function is
+the same that selects a CPU in RPS, but as the number of buckets can
+be much larger than the number of CPUs, flow limit has finer-grained
+identification of large flows and fewer false positives. The default
+table has 4096 buckets. This value can be modified through sysctl
+
+ net.core.flow_limit_table_len
+
+The value is only consulted when a new table is allocated. Modifying
+it does not update active tables.
+
+== Suggested Configuration
+
+Flow limit is useful on systems with many concurrent connections,
+where a single connection taking up 50% of a CPU indicates a problem.
+In such environments, enable the feature on all CPUs that handle
+network rx interrupts (as set in /proc/irq/N/smp_affinity).
+
+The feature depends on the input packet queue length to exceed
+the flow limit threshold (50%) + the flow history length (256).
+Setting net.core.netdev_max_backlog to either 1000 or 10000
+performed well in experiments.

+PMU Event Based Branches
+========================
+
+Event Based Branches (EBBs) are a feature which allows the hardware to
+branch directly to a specified user space address when certain events occur.
+
+The full specification is available in Power ISA v2.07:
+
+  https://www.power.org/documentation/power-isa-version-2-07/
+
+One type of event for which EBBs can be configured is PMU exceptions. This
+document describes the API for configuring the Power PMU to generate EBBs,
+using the Linux perf_events API.
+
+
+Terminology
+-----------
+
+Throughout this document we will refer to an "EBB event" or "EBB events". This
+just refers to a struct perf_event which has set the "EBB" flag in its
+attr.config. All events which can be configured on the hardware PMU are
+possible "EBB events".
+
+
+Background
+----------
+
+When a PMU EBB occurs it is delivered to the currently running process. As such
+EBBs can only sensibly be used by programs for self-monitoring.
+
+It is a feature of the perf_events API that events can be created on other
+processes, subject to standard permission checks. This is also true of EBB
+events, however unless the target process enables EBBs (via mtspr(BESCR)) no
+EBBs will ever be delivered.
+
+This makes it possible for a process to enable EBBs for itself, but not
+actually configure any events. At a later time another process can come along
+and attach an EBB event to the process, which will then cause EBBs to be
+delivered to the first process. It's not clear if this is actually useful.
+
+
+When the PMU is configured for EBBs, all PMU interrupts are delivered to the
+user process. This means once an EBB event is scheduled on the PMU, no non-EBB
+events can be configured. This means that EBB events can not be run
+concurrently with regular 'perf' commands, or any other perf events.
+
+It is however safe to run 'perf' commands on a process which is using EBBs. The
+kernel will in general schedule the EBB event, and perf will be notified that
+its events could not run.
+
+The exclusion between EBB events and regular events is implemented using the
+existing "pinned" and "exclusive" attributes of perf_events. This means EBB
+events will be given priority over other events, unless they are also pinned.
+If an EBB event and a regular event are both pinned, then whichever is enabled
+first will be scheduled and the other will be put in error state. See the
+section below titled "Enabling an EBB event" for more information.
+
+
+Creating an EBB event
+---------------------
+
+To request that an event is counted using EBB, the event code should have bit
+63 set.
+
+EBB events must be created with a particular, and restrictive, set of
+attributes - this is so that they interoperate correctly with the rest of the
+perf_events subsystem.
+
+An EBB event must be created with the "pinned" and "exclusive" attributes set.
+Note that if you are creating a group of EBB events, only the leader can have
+these attributes set.
+
+An EBB event must NOT set any of the "inherit", "sample_period", "freq" or
+"enable_on_exec" attributes.
+
+An EBB event must be attached to a task. This is specified to perf_event_open()
+by passing a pid value, typically 0 indicating the current task.
+
+All events in a group must agree on whether they want EBB. That is all events
+must request EBB, or none may request EBB.
+
+EBB events must specify the PMC they are to be counted on. This ensures
+userspace is able to reliably determine which PMC the event is scheduled on.
+
+
+Enabling an EBB event
+---------------------
+
+Once an EBB event has been successfully opened, it must be enabled with the
+perf_events API. This can be achieved either via the ioctl() interface, or the
+prctl() interface.
+
+However, due to the design of the perf_events API, enabling an event does not
+guarantee that it has been scheduled on the PMU. To ensure that the EBB event
+has been scheduled on the PMU, you must perform a read() on the event. If the
+read() returns EOF, then the event has not been scheduled and EBBs are not
+enabled.
+
+This behaviour occurs because the EBB event is pinned and exclusive. When the
+EBB event is enabled it will force all other non-pinned events off the PMU. In
+this case the enable will be successful. However if there is already an event
+pinned on the PMU then the enable will not be successful.
+
+
+Reading an EBB event
+--------------------
+
+It is possible to read() from an EBB event. However the results are
+meaningless. Because interrupts are being delivered to the user process the
+kernel is not able to count the event, and so will return a junk value.
+
+
+Closing an EBB event
+--------------------
+
+When an EBB event is finished with, you can close it using close() as for any
+regular event. If this is the last EBB event the PMU will be deconfigured and
+no further PMU EBBs will be delivered.
+
+
+EBB Handler
+-----------
+
+The EBB handler is just regular userspace code, however it must be written in
+the style of an interrupt handler. When the handler is entered all registers
+are live (possibly) and so must be saved somehow before the handler can invoke
+other code.
+
+It's up to the program how to handle this. For C programs a relatively simple
+option is to create an interrupt frame on the stack and save registers there.
+
+Fork
+----
+
+EBB events are not inherited across fork. If the child process wishes to use
+EBBs it should open a new event for itself. Similarly the EBB state in
+BESCR/EBBHR/EBBRR is cleared across fork().

+Using PWMs with the sysfs interface
+-----------------------------------
+
+If CONFIG_SYSFS is enabled in your kernel configuration a simple sysfs
+interface is provided to use the PWMs from userspace. It is exposed at
+/sys/class/pwm/. Each probed PWM controller/chip will be exported as
+pwmchipN, where N is the base of the PWM chip. Inside the directory you
+will find:
+
+npwm - The number of PWM channels this chip supports (read-only).
+
+export - Exports a PWM channel for use with sysfs (write-only).
+
+unexport - Unexports a PWM channel from sysfs (write-only).
+
+The PWM channels are numbered using a per-chip index from 0 to npwm-1.
+
+When a PWM channel is exported a pwmX directory will be created in the
+pwmchipN directory it is associated with, where X is the number of the
+channel that was exported. The following properties will then be available:
+
+period - The total period of the PWM signal (read/write).
+	Value is in nanoseconds and is the sum of the active and inactive
+	time of the PWM.
+
+duty_cycle - The active time of the PWM signal (read/write).
+	Value is in nanoseconds and must be less than the period.
+
+polarity - Changes the polarity of the PWM signal (read/write).
+	Writes to this property only work if the PWM chip supports changing
+	the polarity. The polarity can only be changed if the PWM is not
+	enabled. Value is the string "normal" or "inversed".
+
+enable - Enable/disable the PWM signal (read/write).
+	0 - disabled
+	1 - enabled

+2.5 Device Drivers
+
+RapidIO device-specific drivers follow Linux Kernel Driver Model and are
+intended to support specific RapidIO devices attached to the RapidIO network.
+
+2.6 Subsystem Interfaces
+
+RapidIO interconnect specification defines features that may be used to provide
+one or more common service layers for all participating RapidIO devices. These
+common services may act separately from device-specific drivers or be used by
+device-specific drivers. Example of such service provider is the RIONET driver
+which implements Ethernet-over-RapidIO interface. Because only one driver can be
+registered for a device, all common RapidIO services have to be registered as
+subsystem interfaces. This allows to have multiple common services attached to
+the same device without blocking attachment of a device-specific driver.
+
 3. Subsystem Initialization
 ---------------------------
 
 In order to initialize the RapidIO subsystem, a platform must initialize and
 register at least one master port within the RapidIO network. To register mport
-within the subsystem controller driver initialization code calls function
+within the subsystem controller driver's initialization code calls function
 rio_register_mport() for each available master port.
 
-RapidIO subsystem uses subsys_initcall() or device_initcall() to perform
-controller initialization (depending on controller device type).
-
 After all active master ports are registered with a RapidIO subsystem,
 an enumeration and/or discovery routine may be called automatically or
 by user-space command.
 
+RapidIO subsystem can be configured to be built as a statically linked or
+modular component of the kernel (see details below).

+assigning a host destination ID greater than or equal to zero. The host
+destination ID can be assigned to a master port using various methods depending
+on RapidIO subsystem build configuration:
+
+  (a) For a statically linked RapidIO subsystem core use command line parameter
+  "rapidio.hdid=" with a list of destination ID assignments in order of mport
+  device registration. For example, in a system with two RapidIO controllers
+  the command line parameter "rapidio.hdid=-1,7" will result in assignment of
+  the host destination ID=7 to the second RapidIO controller, while the first
+  one will be assigned destination ID=-1.
+
+  (b) If the RapidIO subsystem core is built as a loadable module, in addition
+  to the method shown above, the host destination ID(s) can be specified using
+  traditional methods of passing module parameter "hdid=" during its loading:
+  - from command line: "modprobe rapidio hdid=-1,7", or
+  - from modprobe configuration file using configuration command "options",
+    like in this example: "options rapidio hdid=-1,7". An example of modprobe
+    configuration file is provided in the section below.
+
+  NOTES:
+  (i) if "hdid=" parameter is omitted all available mport will be assigned
+  destination ID = -1;
+  (ii) the "hdid=" parameter in systems with multiple mports can have
+  destination ID assignments omitted from the end of list (default = -1).
+
+If the host device ID for a specific master port is set to -1, the discovery
+process will be performed for it.
 
 The enumeration and discovery routines use RapidIO maintenance transactions
 to access the configuration space of devices.
 
+NOTE: If RapidIO switch-specific device drivers are built as loadable modules
+they must be loaded before enumeration/discovery process starts.
+This requirement is cased by the fact that enumeration/discovery methods invoke
+vendor-specific callbacks on early stages.

+
+This driver register CPU digital temperature package level sensor as a thermal
+zone with maximum two user mode configurable trip points. Number of trip points
+depends on the capability of the package. Once the trip point is violated,

+
+This contains two trip points:

+User can set any temperature between 0 to TJ-Max temperature. Temperature units
+are in milli-degree Celsius. Refer to "Documentation/thermal/sysfs-api.txt" for

+Any value other than 0 in these trip points, can trigger thermal notifications.
+Setting 0, stops sending thermal notifications.

+PPC64 sPAPR implementation note
+-------------------------------------------------------------------------------
+
+This implementation has some specifics:
+
+1) Only one IOMMU group per container is supported as an IOMMU group
+represents the minimal entity which isolation can be guaranteed for and
+groups are allocated statically, one per a Partitionable Endpoint (PE)
+(PE is often a PCI domain but not always).
+
+2) The hardware supports so called DMA windows - the PCI address range
+within which DMA transfer is allowed, any attempt to access address space
+out of the window leads to the whole PE isolation.
+
+3) PPC64 guests are paravirtualized but not fully emulated. There is an API
+to map/unmap pages for DMA, and it normally maps 1..32 pages per call and
+currently there is no way to reduce the number of calls. In order to make things
+faster, the map/unmap handling has been implemented in real mode which provides
+an excellent performance which has limitations such as inability to do
+locked pages accounting in real time.
+
+So 3 additional ioctls have been added:
+
+	VFIO_IOMMU_SPAPR_TCE_GET_INFO - returns the size and the start
+		of the DMA window on the PCI bus.
+
+	VFIO_IOMMU_ENABLE - enables the container. The locked pages accounting
+		is done at this point. This lets user first to know what
+		the DMA window is and adjust rlimit before doing any real job.
+
+	VFIO_IOMMU_DISABLE - disables the container.
+
+
+The code flow from the example above should be slightly changed:
+
+	.....
+	/* Add the group to the container */
+	ioctl(group, VFIO_GROUP_SET_CONTAINER, &container);
+
+	/* Enable the IOMMU model we want */
+	ioctl(container, VFIO_SET_IOMMU, VFIO_SPAPR_TCE_IOMMU)

+	vfio_iommu_spapr_tce_info spapr_iommu_info;
+	ioctl(container, VFIO_IOMMU_SPAPR_TCE_GET_INFO, &spapr_iommu_info);

+		/* Cannot enable container, may be low rlimit */
+
+	/* Allocate some space and setup a DMA mapping */
+	dma_map.vaddr = mmap(0, 1024 * 1024, PROT_READ | PROT_WRITE,
+			     MAP_PRIVATE | MAP_ANONYMOUS, 0, 0);
+
+	dma_map.size = 1024 * 1024;
+	dma_map.iova = 0; /* 1MB starting at 0x0 from device view */

+There are currently two ways to register subdevices with the V4L2 core. The
+first (traditional) possibility is to have subdevices registered by bridge
+drivers. This can be done when the bridge driver has the complete information
+about subdevices connected to it and knows exactly when to register them. This
+is typically the case for internal subdevices, like video data processing units
+within SoCs or complex PCI(e) boards, camera sensors in USB cameras or connected
+to SoCs, which pass information about them to bridge drivers, usually in their
+platform data.
+
+There are however also situations where subdevices have to be registered
+asynchronously to bridge devices. An example of such a configuration is a Device
+Tree based system where information about subdevices is made available to the
+system independently from the bridge devices, e.g. when subdevices are defined
+in DT as I2C device nodes. The API used in this second case is described further

+In the asynchronous case subdevice probing can be invoked independently of the
+bridge driver availability. The subdevice driver then has to verify whether all
+the requirements for a successful probing are satisfied. This can include a
+check for a master clock availability. If any of the conditions aren't satisfied
+the driver might decide to return -EPROBE_DEFER to request further reprobing
+attempts. Once all conditions are met the subdevice shall be registered using
+the v4l2_async_register_subdev() function. Unregistration is performed using

+stored in a global list of subdevices, ready to be picked up by bridge drivers.

+Bridge drivers in turn have to register a notifier object with an array of
+subdevice descriptors that the bridge device needs for its operation. This is
+performed using the v4l2_async_notifier_register() call. To unregister the

+V4L2 clocks
+-----------
+
+Many subdevices, like camera sensors, TV decoders and encoders, need a clock
+signal to be supplied by the system. Often this clock is supplied by the
+respective bridge device. The Linux kernel provides a Common Clock Framework for
+this purpose. However, it is not (yet) available on all architectures. Besides,
+the nature of the multi-functional (clock, data + synchronisation, I2C control)
+connection of subdevices to the system might impose special requirements on the
+clock API usage. E.g. V4L2 has to support clock provider driver unregistration
+while a subdevice driver is holding a reference to the clock. For these reasons
+a V4L2 clock helper API has been developed and is provided to bridge and
+subdevice drivers.
+
+The API consists of two parts: two functions to register and unregister a V4L2
+clock source: v4l2_clk_register() and v4l2_clk_unregister() and calls to control
+a clock object, similar to the respective generic clock API calls:
+v4l2_clk_get(), v4l2_clk_put(), v4l2_clk_enable(), v4l2_clk_disable(),
+v4l2_clk_get_rate(), and v4l2_clk_set_rate(). Clock suppliers have to provide
+clock operations that will be called when clock users invoke respective API
+methods.
+
+It is expected that once the CCF becomes available on all relevant
+architectures this API will be removed.

+Zapping all pages (page generation count)
+=========================================
+
+For the large memory guests, walking and zapping all pages is really slow
+(because there are a lot of pages), and also blocks memory accesses of
+all VCPUs because it needs to hold the MMU lock.
+
+To make it be more scalable, kvm maintains a global generation number
+which is stored in kvm->arch.mmu_valid_gen.  Every shadow page stores
+the current global generation-number into sp->mmu_valid_gen when it
+is created.  Pages with a mismatching generation number are "obsolete".
+
+When KVM need zap all shadow pages sptes, it just simply increases the global
+generation-number then reload root shadow pages on all vcpus.  As the VCPUs
+create new shadow page tables, the old pages are not used because of the
+mismatching generation number.
+
+KVM then walks through all pages and zaps obsolete pages.  While the zap
+operation needs to take the MMU lock, the lock can be released periodically
+so that the VCPUs can make progress.
+
+Fast invalidation of MMIO sptes
+===============================
+
+As mentioned in "Reaction to events" above, kvm will cache MMIO
+information in leaf sptes.  When a new memslot is added or an existing
+memslot is changed, this information may become stale and needs to be
+invalidated.  This also needs to hold the MMU lock while walking all
+shadow pages, and is made more scalable with a similar technique.
+
+MMIO sptes have a few spare bits, which are used to store a
+generation number.  The global generation number is stored in
+kvm_memslots(kvm)->generation, and increased whenever guest memory info
+changes.  This generation number is distinct from the one described in
+the previous section.
+
+When KVM finds an MMIO spte, it checks the generation number of the spte.
+If the generation number of the spte does not equal the global generation
+number, it will ignore the cached MMIO information and handle the page
+fault through the slow path.
+
+Since only 19 bits are used to store generation-number on mmio spte, all
+pages are zapped when there is an overflow.

+     written to since step 1.
+
+
+  Internally, to do this tracking, the writable bit is cleared from PTEs
+when the soft-dirty bit is cleared. So, after this, when the task tries to
+modify a page at some virtual address the #PF occurs and the kernel sets
+the soft-dirty bit on the respective PTE.
+
+  Note, that although all the task's address space is marked as r/o after the
+soft-dirty bits clear, the #PF-s that occur after that are processed fast.
+This is so, since the pages are still mapped to physical memory, and thus all

+bits on the PTE.

+Overview:
+
+Zswap is a lightweight compressed cache for swap pages. It takes pages that are
+in the process of being swapped out and attempts to compress them into a
+dynamically allocated RAM-based memory pool.  zswap basically trades CPU cycles
+for potentially reduced swap I/O.  This trade-off can also result in a
+significant performance improvement if reads from the compressed cache are
+faster than reads from a swap device.
+
+NOTE: Zswap is a new feature as of v3.11 and interacts heavily with memory
+reclaim.  This interaction has not be fully explored on the large set of
+potential configurations and workloads that exist.  For this reason, zswap
+is a work in progress and should be considered experimental.
+
+Some potential benefits:
+* Desktop/laptop users with limited RAM capacities can mitigate the
+    performance impact of swapping.
+* Overcommitted guests that share a common I/O resource can
+    dramatically reduce their swap I/O pressure, avoiding heavy handed I/O
+    throttling by the hypervisor. This allows more work to get done with less
+    impact to the guest workload and guests sharing the I/O subsystem
+* Users with SSDs as swap devices can extend the life of the device by
+    drastically reducing life-shortening writes.
+
+Zswap evicts pages from compressed cache on an LRU basis to the backing swap
+device when the compressed pool reaches it size limit.  This requirement had
+been identified in prior community discussions.
+
+To enabled zswap, the "enabled" attribute must be set to 1 at boot time.  e.g.
+zswap.enabled=1
+
+Design:
+
+Zswap receives pages for compression through the Frontswap API and is able to
+evict pages from its own compressed pool on an LRU basis and write them back to
+the backing swap device in the case that the compressed pool is full.
+
+Zswap makes use of zbud for the managing the compressed memory pool.  Each
+allocation in zbud is not directly accessible by address.  Rather, a handle is
+return by the allocation routine and that handle must be mapped before being
+accessed.  The compressed memory pool grows on demand and shrinks as compressed
+pages are freed.  The pool is not preallocated.
+
+When a swap page is passed from frontswap to zswap, zswap maintains a mapping
+of the swap entry, a combination of the swap type and swap offset, to the zbud
+handle that references that compressed swap page.  This mapping is achieved
+with a red-black tree per swap type.  The swap offset is the search key for the
+tree nodes.
+
+During a page fault on a PTE that is a swap entry, frontswap calls the zswap
+load function to decompress the page into the page allocated by the page fault
+handler.
+
+Once there are no PTEs referencing a swap page stored in zswap (i.e. the count
+in the swap_map goes to 0) the swap code calls the zswap invalidate function,
+via frontswap, to free the compressed entry.
+
+Zswap seeks to be simple in its policies.  Sysfs attributes allow for one user
+controlled policies:
+* max_pool_percent - The maximum percentage of memory that the compressed
+    pool can occupy.
+
+Zswap allows the compressor to be selected at kernel boot time by setting the
+“compressor” attribute.  The default compressor is lzo.  e.g.
+zswap.compressor=deflate
+
+A debugfs interface is provided for various statistic about pool size, number
+of pages stored, and various counters for the reasons pages are rejected.

-config VT
-	bool "Virtual terminal"
-	---help---
-	  If you say Y here, you will get support for terminal devices with
-	  display and keyboard devices. These are called "virtual" because you
-	  can run several virtual terminals (also called virtual consoles) on
-	  one physical terminal. This is rather useful, for example one
-	  virtual terminal can collect system messages and warnings, another
-	  one can be used for a text-mode user session, and a third could run
-	  an X session, all in parallel. Switching between virtual terminals
-	  is done with certain key combinations, usually Alt-<function key>.
-
-	  The setterm command ("man setterm") can be used to change the
-	  properties (such as colors or beeping) of a virtual terminal. The
-	  man page console_codes(4) ("man console_codes") contains the special
-	  character sequences that can be used to change those properties
-	  directly. The fonts used on virtual terminals can be changed with
-	  the setfont ("man setfont") command and the key bindings are defined
-	  with the loadkeys ("man loadkeys") command.
-
-	  You need at least one virtual terminal device in order to make use
-	  of your keyboard and monitor. Therefore, only people configuring an
-	  embedded system would want to say N here in order to save some
-	  memory; the only way to log into such a system is then via a serial
-	  or network connection.
-
-	  If unsure, say Y, or else you won't be able to do much with your new
-	  shiny Linux system :-)
-
-config VT_CONSOLE
-	bool "Support for console on virtual terminal"
-	depends on VT
-	---help---
-	  The system console is the device which receives all kernel messages
-	  and warnings and which allows logins in single user mode. If you
-	  answer Y here, a virtual terminal (the device used to interact with
-	  a physical terminal) can be used as system console. This is the most
-	  common mode of operations, so you should say Y here unless you want
-	  the kernel messages be output only to a serial port (in which case
-	  you should say Y to "Console on serial port", below).
-
-	  If you do say Y here, by default the currently visible virtual
-	  terminal (/dev/tty0) will be used as system console. You can change
-	  that with a kernel command line option such as "console=tty3" which
-	  would use the third virtual terminal as system console. (Try "man
-	  bootparam" or see the documentation of your boot loader (lilo or
-	  loadlin) about how to pass options to the kernel at boot time.)
-
-	  If unsure, say Y.

-comment "Unix98 PTY support"
-
-config UNIX98_PTYS
-	bool "Unix98 PTY support"
-	---help---
-	  A pseudo terminal (PTY) is a software device consisting of two
-	  halves: a master and a slave. The slave device behaves identical to
-	  a physical terminal; the master device is used by a process to
-	  read data from and write data to the slave, thereby emulating a
-	  terminal. Typical programs for the master side are telnet servers
-	  and xterms.
-
-	  Linux has traditionally used the BSD-like names /dev/ptyxx for
-	  masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
-	  has a number of problems. The GNU C library glibc 2.1 and later,
-	  however, supports the Unix98 naming standard: in order to acquire a
-	  pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
-	  terminal is then made available to the process and the pseudo
-	  terminal slave can be accessed as /dev/pts/<number>. What was
-	  traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
-
-	  The entries in /dev/pts/ are created on the fly by a virtual
-	  file system; therefore, if you say Y here you should say Y to
-	  "/dev/pts file system for Unix98 PTYs" as well.
-
-	  If you want to say Y here, you need to have the C library glibc 2.1
-	  or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
-	  Read the instructions in <file:Documentation/Changes> pertaining to
-	  pseudo terminals. It's safe to say N.

+/** Overview:
+ *  EEH, or "Extended Error Handling" is a PCI bridge technology for
+ *  dealing with PCI bus errors that can't be dealt with within the
+ *  usual PCI framework, except by check-stopping the CPU.  Systems
+ *  that are designed for high-availability/reliability cannot afford
+ *  to crash due to a "mere" PCI error, thus the need for EEH.
+ *  An EEH-capable bridge operates by converting a detected error
+ *  into a "slot freeze", taking the PCI adapter off-line, making
+ *  the slot behave, from the OS'es point of view, as if the slot
+ *  were "empty": all reads return 0xff's and all writes are silently
+ *  ignored.  EEH slot isolation events can be triggered by parity
+ *  errors on the address or data busses (e.g. during posted writes),
+ *  which in turn might be caused by low voltage on the bus, dust,
+ *  vibration, humidity, radioactivity or plain-old failed hardware.
+ *
+ *  Note, however, that one of the leading causes of EEH slot
+ *  freeze events are buggy device drivers, buggy device microcode,
+ *  or buggy device hardware.  This is because any attempt by the
+ *  device to bus-master data to a memory address that is not
+ *  assigned to the device will trigger a slot freeze.   (The idea
+ *  is to prevent devices-gone-wild from corrupting system memory).
+ *  Buggy hardware/drivers will have a miserable time co-existing
+ *  with EEH.
+ *
+ *  Ideally, a PCI device driver, when suspecting that an isolation
+ *  event has occurred (e.g. by reading 0xff's), will then ask EEH
+ *  whether this is the case, and then take appropriate steps to
+ *  reset the PCI slot, the PCI device, and then resume operations.
+ *  However, until that day,  the checking is done here, with the
+ *  eeh_check_failure() routine embedded in the MMIO macros.  If
+ *  the slot is found to be isolated, an "EEH Event" is synthesized
+ *  and sent out for processing.
+ */
+
+/* If a device driver keeps reading an MMIO register in an interrupt
+ * handler after a slot isolation event, it might be broken.
+ * This sets the threshold for how many read attempts we allow
+ * before printing an error message.

-/** Overview:
- *  EEH, or "Extended Error Handling" is a PCI bridge technology for
- *  dealing with PCI bus errors that can't be dealt with within the
- *  usual PCI framework, except by check-stopping the CPU.  Systems
- *  that are designed for high-availability/reliability cannot afford
- *  to crash due to a "mere" PCI error, thus the need for EEH.
- *  An EEH-capable bridge operates by converting a detected error
- *  into a "slot freeze", taking the PCI adapter off-line, making
- *  the slot behave, from the OS'es point of view, as if the slot
- *  were "empty": all reads return 0xff's and all writes are silently
- *  ignored.  EEH slot isolation events can be triggered by parity
- *  errors on the address or data busses (e.g. during posted writes),
- *  which in turn might be caused by low voltage on the bus, dust,
- *  vibration, humidity, radioactivity or plain-old failed hardware.
- *
- *  Note, however, that one of the leading causes of EEH slot
- *  freeze events are buggy device drivers, buggy device microcode,
- *  or buggy device hardware.  This is because any attempt by the
- *  device to bus-master data to a memory address that is not
- *  assigned to the device will trigger a slot freeze.   (The idea
- *  is to prevent devices-gone-wild from corrupting system memory).
- *  Buggy hardware/drivers will have a miserable time co-existing
- *  with EEH.
- *
- *  Ideally, a PCI device driver, when suspecting that an isolation
- *  event has occurred (e.g. by reading 0xff's), will then ask EEH
- *  whether this is the case, and then take appropriate steps to
- *  reset the PCI slot, the PCI device, and then resume operations.
- *  However, until that day,  the checking is done here, with the
- *  eeh_check_failure() routine embedded in the MMIO macros.  If
- *  the slot is found to be isolated, an "EEH Event" is synthesized
- *  and sent out for processing.
- */
-
-/* If a device driver keeps reading an MMIO register in an interrupt
- * handler after a slot isolation event, it might be broken.
- * This sets the threshold for how many read attempts we allow
- * before printing an error message.

+                                  Any attempt to change BL using VBIOS function or enable VariBri from PP table is not effective since ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==0;
+                                  
+                                  When it's set to a non-zero frequency, the BackLight is controlled by GPU (SW) in one of two ways below:
+                                  1. SW uses the GPU BL PWM output to control the BL, in chis case, this non-zero frequency determines what freq GPU should use;
+                                  VBIOS will set up proper PWM frequency and ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1,as the result,
+                                  Changing BL using VBIOS function is functional in both driver and non-driver present environment; 
+                                  and enabling VariBri under the driver environment from PP table is optional.
+
+                                  2. SW uses other means to control BL (like DPCD),this non-zero frequency serves as a flag only indicating
+                                  that BL control from GPU is expected.
+                                  VBIOS will NOT set up PWM frequency but make ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1
+                                  Changing BL using VBIOS function could be functional in both driver and non-driver present environment,but
+                                  it's per platform 
+                                  and enabling VariBri under the driver environment from PP table is optional.

+ *
+ * Module registration is sequential. Unregistration is done in reverse order.
+ * After device detection, the needed modules are loaded. Users can trigger
+ * re-detection which causes all modules to be unloaded and then reload the
+ * modules for the new detected device.
+ *
+ * wdata->input is a shared input device. It is always initialized prior to
+ * module registration. If at least one registered module is marked as
+ * WIIMOD_FLAG_INPUT, then the input device will get registered after all
+ * modules were registered.
+ * Please note that it is unregistered _before_ the "remove" callbacks are
+ * called. This guarantees that no input interaction is done, anymore. However,
+ * the wiimote core keeps a reference to the input device so it is freed only
+ * after all modules were removed. It is safe to send events to unregistered
+ * input devices.

+ * Bootloader Messaging Interface (BMI)

+ * application entry PC.
+ *
+ * It is used to download an application to QCA988x, to provide
+ * patches to code that is already resident on QCA988x, and generally
+ * to examine and modify state.  The Host has an opportunity to use
+ * BMI only once during bootup.  Once the Host issues a BMI_DONE
+ * command, this opportunity ends.
+ *
+ * The Host writes BMI requests to mailbox0, and reads BMI responses
+ * from mailbox0.   BMI requests all begin with a command
+ * (see below for specific commands), and are followed by
+ * command-specific data.
+ *
+ * Flow control:
+ * The Host can only issue a command once the Target gives it a
+ * "BMI Command Credit", using AR8K Counter #4.  As soon as the
+ * Target has completed a command, it issues another BMI Command
+ * Credit (so the Host can issue the next command).

+ * communication between Host and Target over a PCIe interconnect.
+ */
+
+/*
+ * A single CopyEngine (CE) comprises two "rings":
+ *   a source ring
+ *   a destination ring
+ *
+ * Each ring consists of a number of descriptors which specify
+ * an address, length, and meta-data.
+ *
+ * Typically, one side of the PCIe interconnect (Host or Target)
+ * controls one ring and the other side controls the other ring.
+ * The source side chooses when to initiate a transfer and it
+ * chooses what to send (buffer address, length). The destination
+ * side keeps a supply of "anonymous receive buffers" available and
+ * it handles incoming data as it arrives (when the destination
+ * recieves an interrupt).
+ *
+ * The sender may send a simple buffer (address/length) or it may
+ * send a small list of buffers.  When a small list is sent, hardware
+ * "gathers" these and they end up in a single destination buffer
+ * with a single interrupt.
+ *
+ * There are several "contexts" managed by this layer -- more, it
+ * may seem -- than should be needed. These are provided mainly for

+/*
+ * This file specifies the WMI interface for the Unified Software
+ * Architecture.
+ *
+ * It includes definitions of all the commands and events. Commands are
+ * messages from the host to the target. Events and Replies are messages
+ * from the target to the host.
+ *
+ * Ownership of correctness in regards to WMI commands belongs to the host
+ * driver and the target is not required to validate parameters for value,
+ * proper range, or any other checking.
+ *
+ * Guidelines for extending this interface are below.
+ *
+ * 1. Add new WMI commands ONLY within the specified range - 0x9000 - 0x9fff
+ *
+ * 2. Use ONLY u32 type for defining member variables within WMI
+ *    command/event structures. Do not use u8, u16, bool or
+ *    enum types within these structures.
+ *
+ * 3. DO NOT define bit fields within structures. Implement bit fields
+ *    using masks if necessary. Do not use the programming language's bit
+ *    field definition.
+ *
+ * 4. Define macros for encode/decode of u8, u16 fields within
+ *    the u32 variables. Use these macros for set/get of these fields.
+ *    Try to use this to optimize the structure without bloating it with
+ *    u32 variables for every lower sized field.
+ *
+ * 5. Do not use PACK/UNPACK attributes for the structures as each member
+ *    variable is already 4-byte aligned by virtue of being a u32
+ *    type.
+ *
+ * 6. Comment each parameter part of the WMI command/event structure by
+ *    using the 2 stars at the begining of C comment instead of one star to
+ *    enable HTML document generation using Doxygen.

+# lpfc_max_luns: maximum allowed LUN ID. This is the highest LUN ID that
+#    will be scanned by the SCSI midlayer when sequential scanning is
+#    used; and is also the highest LUN ID allowed when the SCSI midlayer
+#    parses REPORT_LUN responses. The lpfc driver has no LUN count or
+#    LUN ID limit, but the SCSI midlayer requires this field for the uses
+#    above. The lpfc driver limits the default value to 255 for two reasons.
+#    As it bounds the sequential scan loop, scanning for thousands of luns
+#    on a target can take minutes of wall clock time.  Additionally,
+#    there are FC targets, such as JBODs, that only recognize 8-bits of
+#    LUN ID. When they receive a value greater than 8 bits, they chop off
+#    the high order bits. In other words, they see LUN IDs 0, 256, 512,
+#    and so on all as LUN ID 0. This causes the linux kernel, which sees
+#    valid responses at each of the LUN IDs, to believe there are multiple
+#    devices present, when in fact, there is only 1.
+#    A customer that is aware of their target behaviors, and the results as
+#    indicated above, is welcome to increase the lpfc_max_luns value.
+#    As mentioned, this value is not used by the lpfc driver, only the

- * TI_BANDGAP_FEATURE_TSHUT - used when the thermal shutdown signal output

- * TI_BANDGAP_FEATURE_TSHUT_CONFIG - used when the bandgap device has control
- *      over the thermal shutdown configuration. This means that the thermal
- *      shutdown thresholds are programmable, for instance.
- *
- * TI_BANDGAP_FEATURE_TALERT - used when the bandgap device instance outputs

-* Texas Instrument OMAP SCM bandgap bindings
-
-In the System Control Module, OMAP supplies a voltage reference
-and a temperature sensor feature that are gathered in the band
-gap voltage and temperature sensor (VBGAPTS) module. The band
-gap provides current and voltage reference for its internal
-circuits and other analog IP blocks. The analog-to-digital
-converter (ADC) produces an output value that is proportional
-to the silicon temperature.
-
-Required properties:
-- compatible : Should be:
-  - "ti,omap4430-bandgap" : for OMAP4430 bandgap
-  - "ti,omap4460-bandgap" : for OMAP4460 bandgap
-  - "ti,omap4470-bandgap" : for OMAP4470 bandgap
-  - "ti,omap5430-bandgap" : for OMAP5430 bandgap
-- interrupts : this entry should indicate which interrupt line
-the talert signal is routed to;
-Specific:
-- ti,tshut-gpio : this entry should be used to inform which GPIO
-line the tshut signal is routed to;
-- regs : this entry must also be specified and it is specific
-to each bandgap version, because the mapping may change from
-soc to soc, apart of depending on available features.
-
-Example:
-OMAP4430:
-bandgap {
-	reg = <0x4a002260 0x4 0x4a00232C 0x4>;
-	compatible = "ti,omap4430-bandgap";
-};
-
-OMAP4460:
-bandgap {

+ * TI_BANDGAP_FEATURE_MODE_CONFIG - used when it is possible to choose which
+ *      mode, continuous or one shot, the bandgap device instance will operate.
+ *
+ * TI_BANDGAP_FEATURE_COUNTER - used when the bandgap device instance allows
+ *      programming the update interval of its internal state machine.
+ *
+ * TI_BANDGAP_FEATURE_POWER_SWITCH - used when the bandgap device allows
+ *      itself to be switched on/off.

+ *	a delay programming based on distinct values.

- * In the worst case, when both user and group quotas are on,

+ * We have the possibility of all three quota types being active at once, and
+ * hence free space modification requires modification of all three current
+ * dquots in a single transaction. For this case we need to have a reservation
+ * of at least 3 dquots.
+ *
+ * However, a chmod operation can change both UID and GID in a single
+ * transaction, resulting in requiring {old, new} x {uid, gid} dquots to be
+ * modified. Hence for this case we need to reserve space for at least 4 dquots.
+ *
+ * And in the worst case, there's a rename operation that can be modifying up to
+ * 4 inodes with dquots attached to them. In reality, the only inodes that can
+ * have their dquots modified are the source and destination directory inodes
+ * due to directory name creation and removal. That can require space allocation
+ * and/or freeing on both directory inodes, and hence all three dquots on each
+ * inode can be modified. And if the directories are world writeable, all the
+ * dquots can be unique and so 6 dquots can be modified....
+ *
+ * And, of course, we also need to take into account the dquot log format item

+ * Percpu refcounts:
+ * (C) 2012 Google, Inc.
+ * Author: Kent Overstreet <koverstreet@google.com>
+ *
+ * This implements a refcount with similar semantics to atomic_t - atomic_inc(),
+ * atomic_dec_and_test() - but percpu.
+ *
+ * There's one important difference between percpu refs and normal atomic_t
+ * refcounts; you have to keep track of your initial refcount, and then when you
+ * start shutting down you call percpu_ref_kill() _before_ dropping the initial
+ * refcount.
+ *
+ * The refcount will have a range of 0 to ((1U << 31) - 1), i.e. one bit less
+ * than an atomic_t - this is because of the way shutdown works, see
+ * percpu_ref_kill()/PCPU_COUNT_BIAS.
+ *
+ * Before you call percpu_ref_kill(), percpu_ref_put() does not check for the
+ * refcount hitting 0 - it can't, if it was in percpu mode. percpu_ref_kill()
+ * puts the ref back in single atomic_t mode, collecting the per cpu refs and
+ * issuing the appropriate barriers, and then marks the ref as shutting down so
+ * that percpu_ref_put() will check for the ref hitting 0.  After it returns,
+ * it's safe to drop the initial ref.
+ *
+ * USAGE:
+ *
+ * See fs/aio.c for some example usage; it's used there for struct kioctx, which
+ * is created when userspaces calls io_setup(), and destroyed when userspace
+ * calls io_destroy() or the process exits.
+ *
+ * In the aio code, kill_ioctx() is called when we wish to destroy a kioctx; it
+ * calls percpu_ref_kill(), then hlist_del_rcu() and sychronize_rcu() to remove
+ * the kioctx from the proccess's list of kioctxs - after that, there can't be
+ * any new users of the kioctx (from lookup_ioctx()) and it's then safe to drop
+ * the initial ref with percpu_ref_put().
+ *
+ * Code that does a two stage shutdown like this often needs some kind of
+ * explicit synchronization to ensure the initial refcount can only be dropped
+ * once - percpu_ref_kill() does this for you, it returns true once and false if
+ * someone else already called it. The aio code uses it this way, but it's not
+ * necessary if the code has some other mechanism to synchronize teardown.
+ * around.

+ * s2. Invoke ->css_offline(), mark the cgroup dead and proceed with the
+ *     rest of destruction.  Once all cgroup references are gone, the
+ *     cgroup is RCU-freed.
+ *
+ * This function implements s1.  After this step, @cgrp is gone as far as

+
+	  Compiles debug level messages into the kernel, which would not
+	  otherwise be available at runtime. These messages can then be
+	  enabled/disabled based on various levels of scope - per source file,
+	  function, module, format string, and line number. This mechanism
+	  implicitly compiles in all pr_debug() and dev_dbg() calls, which
+	  enlarges the kernel text size by about 2%.
+
+	  If a source file is compiled with DEBUG flag set, any
+	  pr_debug() calls in it are enabled by default, but can be
+	  disabled at runtime as below.  Note that DEBUG flag is
+	  turned on by many CONFIG_*DEBUG* options.
+
+	  Usage:
+
+	  Dynamic debugging is controlled via the 'dynamic_debug/control' file,
+	  which is contained in the 'debugfs' filesystem. Thus, the debugfs
+	  filesystem must first be mounted before making use of this feature.
+	  We refer the control file as: <debugfs>/dynamic_debug/control. This
+	  file contains a list of the debug statements that can be enabled. The
+	  format for each line of the file is:
+
+		filename:lineno [module]function flags format
+
+	  filename : source file of the debug statement
+	  lineno : line number of the debug statement
+	  module : module that contains the debug statement
+	  function : function that contains the debug statement
+          flags : '=p' means the line is turned 'on' for printing
+          format : the format used for the debug statement
+
+	  From a live system:
+
+		nullarbor:~ # cat <debugfs>/dynamic_debug/control
+		# filename:lineno [module]function flags format
+		fs/aio.c:222 [aio]__put_ioctx =_ "__put_ioctx:\040freeing\040%p\012"

+		fs/aio.c:1770 [aio]sys_io_cancel =_ "calling\040cancel\012"
+
+	  Example usage:
+
+		// enable the message at line 1603 of file svcsock.c
+		nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
+						<debugfs>/dynamic_debug/control

-	help
-
-	  Compiles debug level messages into the kernel, which would not
-	  otherwise be available at runtime. These messages can then be
-	  enabled/disabled based on various levels of scope - per source file,
-	  function, module, format string, and line number. This mechanism
-	  implicitly compiles in all pr_debug() and dev_dbg() calls, which
-	  enlarges the kernel text size by about 2%.
-
-	  If a source file is compiled with DEBUG flag set, any
-	  pr_debug() calls in it are enabled by default, but can be
-	  disabled at runtime as below.  Note that DEBUG flag is
-	  turned on by many CONFIG_*DEBUG* options.
-
-	  Usage:
-
-	  Dynamic debugging is controlled via the 'dynamic_debug/control' file,
-	  which is contained in the 'debugfs' filesystem. Thus, the debugfs
-	  filesystem must first be mounted before making use of this feature.
-	  We refer the control file as: <debugfs>/dynamic_debug/control. This
-	  file contains a list of the debug statements that can be enabled. The
-	  format for each line of the file is:
-
-		filename:lineno [module]function flags format
-
-	  filename : source file of the debug statement
-	  lineno : line number of the debug statement
-	  module : module that contains the debug statement
-	  function : function that contains the debug statement
-          flags : '=p' means the line is turned 'on' for printing
-          format : the format used for the debug statement
-
-	  From a live system:
-
-		nullarbor:~ # cat <debugfs>/dynamic_debug/control
-		# filename:lineno [module]function flags format
-		fs/aio.c:222 [aio]__put_ioctx =_ "__put_ioctx:\040freeing\040%p\012"
-		fs/aio.c:248 [aio]ioctx_alloc =_ "ENOMEM:\040nr_events\040too\040high\012"
-		fs/aio.c:1770 [aio]sys_io_cancel =_ "calling\040cancel\012"
-
-	  Example usage:
-
-		// enable the message at line 1603 of file svcsock.c
-		nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
-						<debugfs>/dynamic_debug/control
-
-		// enable all the messages in file svcsock.c
-		nullarbor:~ # echo -n 'file svcsock.c +p' >
-						<debugfs>/dynamic_debug/control
-
-		// enable all the messages in the NFS server module
-		nullarbor:~ # echo -n 'module nfsd +p' >
-						<debugfs>/dynamic_debug/control
-
-		// enable all 12 messages in the function svc_process()
-		nullarbor:~ # echo -n 'func svc_process +p' >
-						<debugfs>/dynamic_debug/control
-
-		// disable all 12 messages in the function svc_process()

+ * Initially, a percpu refcount is just a set of percpu counters. Initially, we

+ * increment or decrement the local counter. Note that the counter on a
+ * particular cpu can (and will) wrap - this is fine, when we go to shutdown the
+ * percpu counters will all sum to the correct value
+ *
+ * (More precisely: because moduler arithmatic is commutative the sum of all the
+ * pcpu_count vars will be equal to what it would have been if all the gets and
+ * puts were done to a single integer, even if some of the percpu integers
+ * overflow or underflow).
+ *
+ * The real trick to implementing percpu refcounts is shutdown. We can't detect
+ * the ref hitting 0 on every put - this would require global synchronization
+ * and defeat the whole purpose of using percpu refs.
+ *
+ * What we do is require the user to keep track of the initial refcount; we know
+ * the ref can't hit 0 before the user drops the initial ref, so as long as we
+ * convert to non percpu mode before the initial ref is dropped everything
+ * works.
+ *
+ * Converting to non percpu mode is done with some RCUish stuff in
+ * percpu_ref_kill. Additionally, we need a bias value so that the atomic_t

+ * zbud.c
+ *
+ * Copyright (C) 2013, Seth Jennings, IBM
+ *
+ * Concepts based on zcache internal zbud allocator by Dan Magenheimer.
+ *
+ * zbud is an special purpose allocator for storing compressed pages.  Contrary
+ * to what its name may suggest, zbud is not a buddy allocator, but rather an
+ * allocator that "buddies" two compressed pages together in a single memory
+ * page.
+ *
+ * While this design limits storage density, it has simple and deterministic
+ * reclaim properties that make it preferable to a higher density approach when
+ * reclaim will be used.
+ *
+ * zbud works by storing compressed pages, or "zpages", together in pairs in a
+ * single memory page called a "zbud page".  The first buddy is "left
+ * justifed" at the beginning of the zbud page, and the last buddy is "right
+ * justified" at the end of the zbud page.  The benefit is that if either
+ * buddy is freed, the freed buddy space, coalesced with whatever slack space
+ * that existed between the buddies, results in the largest possible free region
+ * within the zbud page.
+ *
+ * zbud also provides an attractive lower bound on density. The ratio of zpages
+ * to zbud pages can not be less than 1.  This ensures that zbud can never "do
+ * harm" by using more pages to store zpages than the uncompressed zpages would
+ * have used on their own.
+ *
+ * zbud pages are divided into "chunks".  The size of the chunks is fixed at
+ * compile time and determined by NCHUNKS_ORDER below.  Dividing zbud pages
+ * into chunks allows organizing unbuddied zbud pages into a manageable number
+ * of unbuddied lists according to the number of free chunks available in the
+ * zbud page.
+ *
+ * The zbud API differs from that of conventional allocators in that the
+ * allocation function, zbud_alloc(), returns an opaque handle to the user,
+ * not a dereferenceable pointer.  The user must map the handle using
+ * zbud_map() in order to get a usable pointer by which to access the
+ * allocation data and unmap the handle with zbud_unmap() when operations
+ * on the allocation data are complete.

+ *
+ * zbud reclaim is different from normal system reclaim in that the reclaim is
+ * done from the bottom, up.  This is because only the bottom layer, zbud, has
+ * information on how the allocations are organized within each zbud page. This
+ * has the potential to create interesting locking situations between zbud and
+ * the user, however.
+ *
+ * To avoid these, this is how zbud_reclaim_page() should be called:
+
+ * The user detects a page should be reclaimed and calls zbud_reclaim_page().
+ * zbud_reclaim_page() will remove a zbud page from the pool LRU list and call
+ * the user-defined eviction handler with the pool and handle as arguments.
+ *
+ * If the handle can not be evicted, the eviction handler should return
+ * non-zero. zbud_reclaim_page() will add the zbud page back to the
+ * appropriate list and try the next zbud page on the LRU up to
+ * a user defined number of retries.
+ *
+ * If the handle is successfully evicted, the eviction handler should
+ * return 0 _and_ should have called zbud_free() on the handle. zbud_free()
+ * contains logic to delay freeing the page if the page is under reclaim,
+ * as indicated by the setting of the PG_reclaim flag on the underlying page.
+ *
+ * If all buddies in the zbud page are successfully evicted, then the
+ * zbud page can be freed.

+ * no pages to evict or an eviction handler is not registered, -EAGAIN if

+ * RAM-based memory pool.  This can result in a significant I/O reduction on
+ * the swap device and, in the case where decompressing from RAM is faster

+ * The index of the slot in which the input aggregate agg is to be
+ * inserted must not be higher than QFQ_MAX_SLOTS-2. There is a '-2'
+ * and not a '-1' because the start time of the group may be moved
+ * backward by one slot after the aggregate has been inserted, and
+ * this would cause non-empty slots to be right-shifted by one
+ * position.
  *
- * If the weight and lmax (max_pkt_size) of the classes do not change,
- * then QFQ+ does meet the above contraint according to the current
- * values of its parameters. In fact, if the weight and lmax of the
- * classes do not change, then, from the theory, QFQ+ guarantees that
- * the slot index is never higher than
- * 2 + QFQ_MAX_AGG_CLASSES * ((1<<QFQ_MTU_SHIFT)/QFQ_MIN_LMAX) *
- * (QFQ_MAX_WEIGHT/QFQ_MAX_WSUM) = 2 + 8 * 128 * (1 / 64) = 18
+ * QFQ+ fully satisfies this bound to the slot index if the parameters
+ * of the classes are not changed dynamically, and if QFQ+ never
+ * happens to postpone the service of agg unjustly, i.e., it never
+ * happens that the aggregate becomes backlogged and eligible, or just
+ * eligible, while an aggregate with a higher approximated finish time
+ * is being served. In particular, in this case QFQ+ guarantees that
+ * the timestamps of agg are low enough that the slot index is never
+ * higher than 2. Unfortunately, QFQ+ cannot provide the same
+ * guarantee if it happens to unjustly postpone the service of agg, or
+ * if the parameters of some class are changed.
  *
- * When the weight of a class is increased or the lmax of the class is
- * decreased, a new aggregate with smaller slot size than the original
- * parent aggregate of the class may happen to be activated. The
- * activation of this aggregate should be properly delayed to when the
- * service of the class has finished in the ideal system tracked by
- * QFQ+. If the activation of the aggregate is not delayed to this
- * reference time instant, then this aggregate may be unjustly served
- * before other aggregates waiting for service. This may cause the
- * above bound to the slot index to be violated for some of these
- * unlucky aggregates.
+ * As for the first event, i.e., an out-of-order service, the
+ * upper bound to the slot index guaranteed by QFQ+ grows to
+ * 2 +
+ * QFQ_MAX_AGG_CLASSES * ((1<<QFQ_MTU_SHIFT)/QFQ_MIN_LMAX) *
+ * (current_max_weight/current_wsum) <= 2 + 8 * 128 * 1.
+ *
+ * The following function deals with this problem by backward-shifting
+ * the timestamps of agg, if needed, so as to guarantee that the slot
+ * index is never higher than QFQ_MAX_SLOTS-2. This backward-shift may
+ * cause the service of other aggregates to be postponed, yet the
+ * worst-case guarantees of these aggregates are not violated.  In
+ * fact, in case of no out-of-order service, the timestamps of agg
+ * would have been even lower than they are after the backward shift,
+ * because QFQ+ would have guaranteed a maximum value equal to 2 for
+ * the slot index, and 2 < QFQ_MAX_SLOTS-2. Hence the aggregates whose
+ * service is postponed because of the backward-shift would have
+ * however waited for the service of agg before being served.
+ *
+ * The other event that may cause the slot index to be higher than 2
+ * for agg is a recent change of the parameters of some class. If the
+ * weight of a class is increased or the lmax (max_pkt_size) of the
+ * class is decreased, then a new aggregate with smaller slot size
+ * than the original parent aggregate of the class may happen to be
+ * activated. The activation of this aggregate should be properly
+ * delayed to when the service of the class has finished in the ideal
+ * system tracked by QFQ+. If the activation of the aggregate is not
+ * delayed to this reference time instant, then this aggregate may be
+ * unjustly served before other aggregates waiting for service. This
+ * may cause the above bound to the slot index to be violated for some
+ * of these unlucky aggregates.
  *
  * Instead of delaying the activation of the new aggregate, which is
- * quite complex, the following inaccurate but simple solution is used:
- * if the slot index is higher than QFQ_MAX_SLOTS-2, then the
- * timestamps of the aggregate are shifted backward so as to let the
- * slot index become equal to QFQ_MAX_SLOTS-2.
+ * quite complex, the above-discussed capping of the slot index is
+ * used to handle also the consequences of a change of the parameters
+ * of a class.

 Threads (hyperthreaded cores) may not be able to enter deeper core states if
 its sibling is utilized.
 Deepest package sleep states may in reality show up as machine/platform wide
 sleep states and can only be entered if all cores are idle. Look up Intel
 manuals (some are provided in the References section) for further details.
+The monitors are named after the CPU family where the sleep state capabilities
+got introduced and may not match exactly the CPU name of the platform.
+For example an IvyBridge processor has sleep state capabilities which got
+introduced in Nehalem and SandyBridge processor families.
+Thus on an IvyBridge processor one will get Nehalem and SandyBridge sleep
+state monitors.
