+Introduction
+============
+
+This module will be used to log the events by any module/driver which
+enables Inter Processor Communication (IPC). Some of the IPC drivers such
+as Message Routers, Multiplexers etc. which act as a passive pipe need
+some mechanism to log their events. Since all such IPC drivers handle a
+large amount of traffic/events, using kernel logs renders kernel logs
+unusable by other drivers and also degrades the performance of IPC
+drivers. This new module will help in logging such high frequency IPC
+driver events while keeping the standard kernel logging mechanism
+intact.
+
+Hardware description
+====================
+
+This module does not drive any hardware resource and will only use the
+kernel memory-space to log the events.
+
+Software description
+====================
+
+Design Goals
+------------
+This module is designed to
+	* support logging for drivers handling large amount of
+	  traffic/events
+	* define & differentiate events/logs from different drivers
+	* support both id-based and stream-based logging
+	* support extracting the logs from both live target & memory dump
+
+IPC Log Context
+----------------
+
+This module will support logging by multiple drivers. To differentiate
+between the multiple drivers that are using this logging mechanism, each
+driver will be assigned a unique context by this module. Associated with
+each context is the logging space, dynamically allocated from the kernel
+memory-space, specific to that context so that the events logged using that
+context will not interfere with other contexts.
+
+Event Logging
+--------------
+
+Every event will be logged as a <Type: Size: Value> combination. Type
+field identifies the type of the event that is logged. Size field represents
+the size of the log information. Value field represents the actual
+information being logged. This approach will support both id-based logging
+and stream-based logging. This approach will also support logging sub-events
+of an event. This module will provide helper routines to encode/decode the
+logs to/from this format.
+
+Encode Context
+---------------
+
+Encode context is a temporary storage space that will be used by the client
+drivers to log the events in <Type: Size: Value> format. The client drivers
+will perform an encode start operation to initialize the encode context
+data structure. Then the client drivers will log their events into the
+encode context. Upon completion of event logging, the client drivers will
+perform an encode end operation to finalize the encode context data
+structure to be logged. Then this updated encode context data structure
+will be written into the client driver's IPC Log Context. The maximum
+event log size will be defined as 256 bytes.
+
+Log Space
+----------
+
+Each context will have an associated log space, which is dynamically
+allocated from the kernel memory-space. The log space is organized as a
+list of kernel memory pages. Each page contains header information which
+is used to differentiate the log kernel page from the other kernel pages.

+		--------------------------------- PAGE_SIZE - 1
+
+This approach will support extracting the logs either from the memory dumps
+or from the live targets using DEBUGFS.
+
+Design
+======
+
+Alternate solutions discussed include using kernel & SMEM logs which are
+limited in size and hence using them render them unusable by other drivers.
+Also kernel logging into serial console is slowing down the performance of
+the drivers by multiple times and sometimes lead to APPs watchdog bite.

+
+The qcom,board-id entry specifies the MSM platform and subtype revision.
+It can optionally be an array of these to indicate multiple hardware that use

+information at boot-up to decide which device tree to use when given multiple
+device trees, some of which may not be compatible with the actual hardware.  It
+is the bootloader's responsibility to pass the correct device tree to the kernel.
+
+Format:
+
+It is expected that the qcom,board-id entry be at the top level of the device
+tree structure.  The format of the entry is:
+
+   qcom,board-id = <platform_id, subtype_id> [, <p2, s2> ...]

-* Low Power Management Resources
-
-The application processor in the MSM can enter several different low power
-states depending on the sleep time and on the required system resources. The
-MSM cannot enter a given low power state if that state involves turning off
-some shared resources which are required by some components of the
-system.The lpm-resources device tree node represents the shared resources
-that need to be monitored for usage requirement to check if a given low power
-state can be entered.Each resource is identified by a combination of the name,
-id,type and key which is also used by the RPM to identify a shared resource.
-The name and resource-type are required nodes; the type, id and key are
-optional nodes which are needed if the resource type is RPM shared resource
-(MSM_LPM_RPM_RS_TYPE).
-
-The nodes for lpm-resources are:
-
-Required Nodes:
-
-- compatible: "qcom,lpm-resources"
-- reg: The numeric level id
-- qcom,name: The name of the low power resource represented
-             as a string.
-- qcom,init-value: Initialization value of the LPM resource represented as
-			decimal value for vdd-dig and vdd-mem resources and
-			as string for pxo and l2 resources.
-
-
-Optional Nodes:
-
-- qcom,type: The type of resource used like smps or pxo
-             represented as a hex value.
-- qcom,id: The id representing a device within a resource type.
-- qcom,key: The key is the specific attribute of the resource being
-            monitored represented as a hex value.
-- qcom,local-resource-type: The property exists only for locally managed
-				resource and is represented as a bool.
-
-Example:
-            qcom,lpm-resources@0 {
-                        reg = <0x0>;
-                        qcom,name = "vdd-dig";

+Battery Profile Data
+
+Battery Data is a collection of battery profile data made available to
+the QPNP Charger and BMS drivers via device tree.
+
+qcom,battery-data node required properties:
+- qcom,rpull-up-kohm : The vadc pullup resistor's resistance value in kOhms.
+- qcom,vref-batt-therm-uv : The vadc voltage used to make readings.
+			For Qualcomm VADCs this should be 1800000uV.
+
+qcom,battery-data can also include any number of children nodes. These children
+nodes will be treated as battery profile data nodes.
+
+Profile data node required properties:
+- qcom,fcc-mah : Full charge count of the battery in milliamp-hours
+- qcom,default-rbatt-mohm : The nominal battery resistance value
+- qcom,rbatt-capacitive-mohm : The capacitive resistance of the battery.
+- qcom,flat-ocv-threshold-uv : The threshold under which the battery can be
+			considered to be in the flat portion of the discharge
+			curve.
+- qcom,max-voltage-uv : The maximum rated voltage of the battery
+- qcom,v-cutoff-uv : The cutoff voltage of the battery at which the device
+			should shutdown gracefully.
+- qcom,chg-term-ua : The termination charging current of the battery.
+- qcom,batt-id-kohm : The battery id resistance of the battery.
+
+Profile data node required subnodes:
+- qcom,fcc-temp-lut : An 1-dimensional lookup table node that encodes
+			temperature to fcc lookup. The units for this lookup
+			table should be degrees celsius to milliamp-hours.
+- qcom,pc-temp-ocv-lut : A 2-dimensional lookup table node that encodes
+			temperature and percent charge to open circuit voltage
+			lookup. The units for this lookup table should be
+			degrees celsius and percent to millivolts.
+- qcom,rbatt-sf-lut : A 2-dimentional lookup table node that encodes
+			temperature and percent charge to battery internal
+			resistance lookup. The units for this lookup table
+			should be degrees celsius and percent to milliohms.
+
+Lookup table required properties:
+- qcom,lut-col-legend : An array that encodes the legend of the lookup table's
+			columns. The length of this array will determine the
+			lookup table's width.
+- qcom,lut-data : An array that encodes the lookup table's data. The size of this
+			array should be equal to the size of qcom,lut-col-legend
+			multiplied by 1 if it's a 1-dimensional table, or
+			the size of qcom,lut-row-legend if it's a 2-dimensional
+			table. The data should be in a flattened row-major
+			representation.
+
+Lookup table optional properties:
+- qcom,lut-row-legend : An array that encodes the legend of the lookup table's rows.
+			If this property exists, then it is assumed that the
+			lookup table is a 2-dimensional table.

+== Introduction ==
+
+Hardware modules that control pin multiplexing or configuration parameters
+such as pull-up/down, tri-state, drive-strength etc are designated as pin
+controllers. Each pin controller must be represented as a node in device tree,
+just like any other hardware module.
+
+Hardware modules whose signals are affected by pin configuration are
+designated client devices. Again, each client device must be represented as a
+node in device tree, just like any other hardware module.
+
+For a client device to operate correctly, certain pin controllers must
+set up certain specific pin configurations. Some client devices need a
+single static pin configuration, e.g. set up during initialization. Others
+need to reconfigure pins at run-time, for example to tri-state pins when the
+device is inactive. Hence, each client device can define a set of named
+states. The number and names of those states is defined by the client device's
+own binding.
+
+The common pinctrl bindings defined in this file provide an infrastructure
+for client device device tree nodes to map those state names to the pin
+configuration used by those states.
+
+Note that pin controllers themselves may also be client devices of themselves.
+For example, a pin controller may set up its own "active" state when the
+driver loads. This would allow representing a board's static pin configuration
+in a single place, rather than splitting it across multiple client device
+nodes. The decision to do this or not somewhat rests with the author of
+individual board device tree files, and any requirements imposed by the
+bindings for the individual client devices in use by that board, i.e. whether
+they require certain specific named states for dynamic pin configuration.
+
+== Pinctrl client devices ==
+
+For each client device individually, every pin state is assigned an integer
+ID. These numbers start at 0, and are contiguous. For each state ID, a unique
+property exists to define the pin configuration. Each state may also be
+assigned a name. When names are used, another property exists to map from
+those names to the integer IDs.
+
+Each client device's own binding determines the set of states the must be
+defined in its device tree node, and whether to define the set of state
+IDs that must be provided, or whether to define the set of state names that
+must be provided.
+
+Required properties:
+pinctrl-0:	List of phandles, each pointing at a pin configuration
+		node. These referenced pin configuration nodes must be child
+		nodes of the pin controller that they configure. Multiple
+		entries may exist in this list so that multiple pin
+		controllers may be configured, or so that a state may be built
+		from multiple nodes for a single pin controller, each
+		contributing part of the overall configuration. See the next
+		section of this document for details of the format of these
+		pin configuration nodes.
+
+		In some cases, it may be useful to define a state, but for it
+		to be empty. This may be required when a common IP block is
+		used in an SoC either without a pin controller, or where the
+		pin controller does not affect the HW module in question. If
+		the binding for that IP block requires certain pin states to
+		exist, they must still be defined, but may be left empty.
+
+Optional properties:
+pinctrl-1:	List of phandles, each pointing at a pin configuration
+		node within a pin controller.
+...
+pinctrl-n:	List of phandles, each pointing at a pin configuration
+		node within a pin controller.
+pinctrl-names:	The list of names to assign states. List entry 0 defines the
+		name for integer state ID 0, list entry 1 for state ID 1, and
+		so on.
+
+For example:
+
+	/* For a client device requiring named states */
+	device {
+		pinctrl-names = "active", "idle";
+		pinctrl-0 = <&state_0_node_a>;
+		pinctrl-1 = <&state_1_node_a &state_1_node_b>;
+	};
+
+	/* For the same device if using state IDs */
+	device {
+		pinctrl-0 = <&state_0_node_a>;
+		pinctrl-1 = <&state_1_node_a &state_1_node_b>;
+	};
+
+	/*
+	 * For an IP block whose binding supports pin configuration,
+	 * but in use on an SoC that doesn't have any pin control hardware
+	 */
+	device {
+		pinctrl-names = "active", "idle";
+		pinctrl-0 = <>;
+		pinctrl-1 = <>;
+	};
+
+== Pin controller devices ==
+
+Pin controller devices should contain the pin configuration nodes that client
+devices reference.
+
+For example:
+
+	pincontroller {
+		... /* Standard DT properties for the device itself elided */
+
+		state_0_node_a {
+			...
+		};
+		state_1_node_a {
+			...
+		};
+		state_1_node_b {
+			...
+		};
+	}
+
+The contents of each of those pin configuration child nodes is defined
+entirely by the binding for the individual pin controller device. There
+exists no common standard for this content.
+
+The pin configuration nodes need not be direct children of the pin controller
+device; they may be grandchildren, for example. Whether this is legal, and
+whether there is any interaction between the child and intermediate parent
+nodes, is again defined entirely by the binding for the individual pin
+controller device.
+
+== Using generic pinconfig options ==
+
+Generic pinconfig parameters can be used by defining a separate node containing
+the applicable parameters (and optional values), like:
+
+pcfg_pull_up: pcfg_pull_up {
+	bias-pull-up;
+	drive-strength = <20>;
+};
+
+This node should then be referenced in the appropriate pinctrl node as a phandle
+and parsed in the driver using the pinconf_generic_parse_dt_config function.
+
+Supported configuration parameters are:
+
+bias-disable		- disable any pin bias
+bias-high-impedance	- high impedance mode ("third-state", "floating")
+bias-bus-hold		- latch weakly
+bias-pull-up		- pull up the pin
+bias-pull-down		- pull down the pin
+bias-pull-pin-default	- use pin-default pull state
+drive-push-pull		- drive actively high and low
+drive-open-drain	- drive with open drain
+drive-open-source	- drive with open source
+drive-strength		- sink or source at most X mA
+input-schmitt-enable	- enable schmitt-trigger mode
+input-schmitt-disable	- disable schmitt-trigger mode
+input-schmitt		- run in schmitt-trigger mode with hysteresis X
+input-debounce		- debounce mode with debound time X
+power-source		- select power source X
+slew-rate		- use slew-rate X
+low-power-enable	- enable low power mode
+low-power-disable	- disable low power mode
+output-low		- set the pin to output mode with low level
+output-high		- set the pin to output mode with high level
+
+Arguments for parameters:
+
+- bias-pull-up, -down and -pin-default take as optional argument 0 to disable
+  the pull, on hardware supporting it the pull strength in Ohm. bias-disable
+  will also disable any active pull.
+
+- drive-strength takes as argument the target strength in mA.
+
+- input-schmitt takes as argument the adjustable hysteresis in a
+  driver-specific format
+
+- input-debounce takes the debounce time as argument or 0 to disable debouncing
+
+- power-source argument is the custom value describing the source to select
+
+- slew-rate takes as argument the target rate in a driver-specific format
+
+All parameters not listed here, do not take an argument.
+
+More in-depth documentation on these parameters can be found in

- * base address of the firmware. This means that if MM is reusable the other
- * two heaps must be allocated in the same region as FW. This is handled by the
- * mem_is_fmem flag in the platform data. In addition the MM heap must be
+ * base address of the firmware. In addition the MM heap must be
  * adjacent to the FW heap for content protection purposes.

+
+    Based on:
+    BMP085 driver, bmp085.c
+    Copyright (c) 2010  Christoph Mair <christoph.mair@gmail.com>
+
+    This driver supports the bmp18x digital barometric pressure
+    and temperature sensors from Bosch Sensortec.
+
+    A pressure measurement is issued by reading from pressure0_input.
+    The return value ranges from 30000 to 110000 pascal with a resulution
+    of 1 pascal (0.01 millibar) which enables measurements from 9000m above
+    to 500m below sea level.
+
+    The temperature can be read from temp0_input. Values range from
+    -400 to 850 representing the ambient temperature in degree celsius
+    multiplied by 10.The resolution is 0.1 celsius.
+
+    Because ambient pressure is temperature dependent, a temperature
+    measurement will be executed automatically even if the user is reading
+    from pressure0_input. This happens if the last temperature measurement
+    has been executed more then one second ago.
+
+    To decrease RMS noise from pressure measurements, the bmp18x can
+    autonomously calculate the average of up to eight samples. This is
+    set up by writing to the oversampling sysfs file. Accepted values
+    are 0, 1, 2 and 3. 2^x when x is the value written to this file
+    specifies the number of samples used to calculate the ambient pressure.
+    RMS noise is specified with six pascal (without averaging) and decreases
+    down to 3 pascal when using an oversampling setting of 3.

- * (3) one of PAGE_SIZE/64 "unbuddied" lists indexed by how many chunks
- * the one unbuddied zbud uses.  The data inside a zbpg cannot be

- *
- * The primary purpose of Transcedent Memory ("tmem") is to map object-oriented
- * "handles" (triples containing a pool id, and object id, and an index), to
- * pages in a page-accessible memory (PAM).  Tmem references the PAM pages via
- * an abstract "pampd" (PAM page-descriptor), which can be operated on by a
- * set of functions (pamops).  Each pampd contains some representation of
- * PAGE_SIZE bytes worth of data. Tmem must support potentially millions of
- * pages and must be able to insert, find, and delete these pages at a
- * potential frequency of thousands per second concurrently across many CPUs,
- * (and, if used with KVM, across many vcpus across many guests).
- * Tmem is tracked with a hierarchy of data structures, organized by
- * the elements in a handle-tuple: pool_id, object_id, and page index.
- * One or more "clients" (e.g. guests) each provide one or more tmem_pools.
- * Each pool, contains a hash table of rb_trees of tmem_objs.  Each
- * tmem_obj contains a radix-tree-like tree of pointers, with intermediate
- * nodes called tmem_objnodes.  Each leaf pointer in this tree points to
- * a pampd, which is accessible only through a small set of callbacks
- * registered by the PAM implementation (see tmem_register_pamops). Tmem
- * does all memory allocation via a set of callbacks registered by the tmem
- * host implementation (e.g. see tmem_register_hostops).
