+Description:
+ The type of interface controlled by <backlight>.
+ "firmware": The driver uses a standard firmware interface
+ "platform": The driver uses a platform-specific interface
+ "raw": The driver controls hardware registers directly
+
+ In the general case, when multiple backlight
+ interfaces are available for a single device, firmware
+ control should be preferred to platform control should
+ be preferred to raw control. Using a firmware
+ interface reduces the probability of confusion with
+ the hardware and the OS independently updating the
+ backlight state. Platform interfaces are mostly a
+ holdover from pre-standardisation of firmware
+ interfaces.

+ <para>Pad-level image format configuration support can be tested by calling

+ <section>
+ <title>Format Negotiation</title>
+
+ <para>Acceptable formats on pads can (and usually do) depend on a number
+ of external parameters, such as formats on other pads, active links, or
+ even controls. Finding a combination of formats on all pads in a video
+ pipeline, acceptable to both application and driver, can't rely on formats
+ enumeration only. A format negotiation mechanism is required.</para>
+
+ <para>Central to the format negotiation mechanism are the get/set format
+ operations. When called with the <structfield>which</structfield> argument
+ set to <constant>V4L2_SUBDEV_FORMAT_TRY</constant>, the
+ &VIDIOC-SUBDEV-G-FMT; and &VIDIOC-SUBDEV-S-FMT; ioctls operate on a set of
+ formats parameters that are not connected to the hardware configuration.
+ Modifying those 'try' formats leaves the device state untouched (this
+ applies to both the software state stored in the driver and the hardware
+ state stored in the device itself).</para>
+
+ <para>While not kept as part of the device state, try formats are stored
+ in the sub-device file handles. A &VIDIOC-SUBDEV-G-FMT; call will return
+ the last try format set <emphasis>on the same sub-device file
+ handle</emphasis>. Several applications querying the same sub-device at
+ the same time will thus not interact with each other.</para>
+
+ <para>To find out whether a particular format is supported by the device,
+ applications use the &VIDIOC-SUBDEV-S-FMT; ioctl. Drivers verify and, if
+ needed, change the requested <structfield>format</structfield> based on
+ device requirements and return the possibly modified value. Applications
+ can then choose to try a different format or accept the returned value and
+ continue.</para>
+
+ <para>Formats returned by the driver during a negotiation iteration are
+ guaranteed to be supported by the device. In particular, drivers guarantee
+ that a returned format will not be further changed if passed to an
+ &VIDIOC-SUBDEV-S-FMT; call as-is (as long as external parameters, such as
+ formats on other pads or links' configuration are not changed).</para>
+
+ <para>Drivers automatically propagate formats inside sub-devices. When a
+ try or active format is set on a pad, corresponding formats on other pads
+ of the same sub-device can be modified by the driver. Drivers are free to
+ modify formats as required by the device. However, they should comply with
+ the following rules when possible:

+ <listitem><para>Formats should be propagated from sink pads to source pads.
+ Modifying a format on a source pad should not modify the format on any

+ </itemizedlist>
+ </para>
+
+ <para>Formats are not propagated across links, as that would involve

+ <title>Cropping and scaling</title>
+
+ <para>Many sub-devices support cropping frames on their input or output
+ pads (or possible even on both). Cropping is used to select the area of
+ interest in an image, typically on a video sensor or video decoder. It can
+ also be used as part of digital zoom implementations to select the area of
+ the image that will be scaled up.</para>
+
+ <para>Crop settings are defined by a crop rectangle and represented in a
+ &v4l2-rect; by the coordinates of the top left corner and the rectangle
+ size. Both the coordinates and sizes are expressed in pixels.</para>
+
+ <para>The crop rectangle is retrieved and set using the
+ &VIDIOC-SUBDEV-G-CROP; and &VIDIOC-SUBDEV-S-CROP; ioctls. Like for pad
+ formats, drivers store try and active crop rectangles. The format
+ negotiation mechanism applies to crop settings as well.</para>
+
+ <para>On input pads, cropping is applied relatively to the current pad
+ format. The pad format represents the image size as received by the
+ sub-device from the previous block in the pipeline, and the crop rectangle
+ represents the sub-image that will be transmitted further inside the
+ sub-device for processing. The crop rectangle be entirely containted
+ inside the input image size.</para>
+

+ <para>Media devices increasingly handle multiple related functions. Many USB
+ cameras include microphones, video capture hardware can also output video,
+ or SoC camera interfaces also perform memory-to-memory operations similar to
+ video codecs.</para>
+ <para>Independent functions, even when implemented in the same hardware, can
+ be modelled as separate devices. A USB camera with a microphone will be
+ presented to userspace applications as V4L2 and ALSA capture devices. The
+ devices' relationships (when using a webcam, end-users shouldn't have to
+ manually select the associated USB microphone), while not made available
+ directly to applications by the drivers, can usually be retrieved from
+ sysfs.</para>
+ <para>With more and more advanced SoC devices being introduced, the current
+ approach will not scale. Device topologies are getting increasingly complex
+ and can't always be represented by a tree structure. Hardware blocks are
+ shared between different functions, creating dependencies between seemingly
+ unrelated devices.</para>
+ <para>Kernel abstraction APIs such as V4L2 and ALSA provide means for
+ applications to access hardware parameters. As newer hardware expose an
+ increasingly high number of those parameters, drivers need to guess what
+ applications really require based on limited information, thereby
+ implementing policies that belong to userspace.</para>

+ <para>Discovering a device internal topology, and configuring it at runtime,
+ is one of the goals of the media controller API. To achieve this, hardware
+ devices are modelled as an oriented graph of building blocks called entities
+ connected through pads.</para>
+ <para>An entity is a basic media hardware or software building block. It can
+ correspond to a large variety of logical blocks such as physical hardware
+ devices (CMOS sensor for instance), logical hardware devices (a building
+ block in a System-on-Chip image processing pipeline), DMA channels or
+ physical connectors.</para>
+ <para>A pad is a connection endpoint through which an entity can interact
+ with other entities. Data (not restricted to video) produced by an entity
+ flows from the entity's output to one or more entity inputs. Pads should not
+ be confused with physical pins at chip boundaries.</para>
+ <para>A link is a point-to-point oriented connection between two pads,
+ either on the same entity or on different entities. Data flows from a source
+ pad to a sink pad.</para>

+
+ <para>This is a multi-planar, two-plane version of the YUV 4:2:0 format.
+The three components are separated into two sub-images or planes.
+<constant>V4L2_PIX_FMT_NV12M</constant> differs from <constant>V4L2_PIX_FMT_NV12
+</constant> in that the two planes are non-contiguous in memory, i.e. the chroma
+plane do not necessarily immediately follows the luma plane.
+The luminance data occupies the first plane. The Y plane has one byte per pixel.
+In the second plane there is a chrominance data with alternating chroma samples.
+The CbCr plane is the same width, in bytes, as the Y plane (and of the image),
+but is half as tall in pixels. Each CbCr pair belongs to four pixels. For example,
+Cb<subscript>0</subscript>/Cr<subscript>0</subscript> belongs to
+Y'<subscript>00</subscript>, Y'<subscript>01</subscript>,
+Y'<subscript>10</subscript>, Y'<subscript>11</subscript>. </para>

+ <para><constant>V4L2_PIX_FMT_NV12M</constant> is intended to be

+ <para>This is a multi-planar format, as opposed to a packed format.
+The three components are separated into three sub- images or planes.
+
+The Y plane is first. The Y plane has one byte per pixel. The Cb data
+constitutes the second plane which is half the width and half
+the height of the Y plane (and of the image). Each Cb belongs to four
+pixels, a two-by-two square of the image. For example,
+Cb<subscript>0</subscript> belongs to Y'<subscript>00</subscript>,
+Y'<subscript>01</subscript>, Y'<subscript>10</subscript>, and
+Y'<subscript>11</subscript>. The Cr data, just like the Cb plane, is
+in the third plane. </para>
+
+ <para>If the Y plane has pad bytes after each row, then the Cb
+and Cr planes have half as many pad bytes after their rows. In other
+words, two Cx rows (including padding) is exactly as long as one Y row
+(including padding).</para>
+
+ <para><constant>V4L2_PIX_FMT_NV12M</constant> is intended to be
+used only in drivers and applications that support the multi-planar API,
+described in <xref linkend="planar-apis"/>. </para>

+ <listitem><para>The Y, U and V components order code, as transferred on the
+ bus. Possible values are YUYV, UYVY, YVYU and VYUY.</para></listitem>
+ <listitem><para>The number of bits per pixel component. All components are
+ transferred on the same number of bits. Common values are 8, 10 and 12.</para>
+ </listitem>
+ <listitem><para>The number of bus samples per pixel. Pixels that are wider than
+ the bus width must be transferred in multiple samples. Common values are
+ 1, 1.5 (encoded as 1_5) and 2.</para></listitem>
+ <listitem><para>The bus width. When the bus width is larger than the number of
+ bits per pixel component, several components are packed in a single bus
+ sample. The components are ordered as specified by the order code, with
+ components on the left of the code transferred in the high order bits.
+ Common values are 8 and 16.</para>

+ <para>This ioctl allows applications to enumerate all frame sizes
+ supported by a sub-device on the given pad for the given media bus format.
+ Supported formats can be retrieved with the &VIDIOC-SUBDEV-ENUM-MBUS-CODE;
+ ioctl.</para>
+
+ <para>To enumerate frame sizes applications initialize the
+ <structfield>pad</structfield>, <structfield>code</structfield> and
+ <structfield>index</structfield> fields of the
+ &v4l2-subdev-mbus-code-enum; and call the
+ <constant>VIDIOC_SUBDEV_ENUM_FRAME_SIZE</constant> ioctl with a pointer to
+ the structure. Drivers fill the minimum and maximum frame sizes or return
+ an &EINVAL; if one of the input parameters is invalid.</para>
+
+ <para>Sub-devices that only support discrete frame sizes (such as most
+ sensors) will return one or more frame sizes with identical minimum and
+ maximum values.</para>
+
+ <para>Not all possible sizes in given [minimum, maximum] ranges need to be
+ supported. For instance, a scaler that uses a fixed-point scaling ratio
+ might not be able to produce every frame size between the minimum and
+ maximum values. Applications must use the &VIDIOC-SUBDEV-S-FMT; ioctl to
+ try the sub-device for an exact supported frame size.</para>
+
+ <para>Available frame sizes may depend on the current 'try' formats at other
+ pads of the sub-device, as well as on the current active links and the
+ current values of V4L2 controls. See &VIDIOC-SUBDEV-G-FMT; for more
+ information about try formats.</para>

-/sys/block/<disk>/queue/iosched/group_isolation
------------------------------------------------
-
-If group_isolation=1, it provides stronger isolation between groups at the
-expense of throughput. By default group_isolation is 0. In general that
-means that if group_isolation=0, expect fairness for sequential workload
-only. Set group_isolation=1 to see fairness for random IO workload also.
-
-Generally CFQ will put random seeky workload in sync-noidle category. CFQ
-will disable idling on these queues and it does a collective idling on group
-of such queues. Generally these are slow moving queues and if there is a
-sync-noidle service tree in each group, that group gets exclusive access to
-disk for certain period. That means it will bring the throughput down if
-group does not have enough IO to drive deeper queue depths and utilize disk
-capacity to the fullest in the slice allocated to it. But the flip side is
-that even a random reader should get better latencies and overall throughput
-if there are lots of sequential readers/sync-idle workload running in the
-system.
-
-If group_isolation=0, then CFQ automatically moves all the random seeky queues
-in the root group. That means there will be no service differentiation for
-that kind of workload. This leads to better throughput as we do collective
-idling on root sync-noidle tree.
-
-By default one should run with group_isolation=0. If that is not sufficient
-and one wants stronger isolation between groups, then set group_isolation=1
-but this will come at cost of reduced throughput.

+* Open PIC Binding
+
+This binding specifies what properties must be available in the device tree
+representation of an Open PIC compliant interrupt controller. This binding is
+based on the binding defined for Open PIC in [1] and is a superset of that
+binding.
+
+Required properties:
+
+ NOTE: Many of these descriptions were paraphrased here from [1] to aid
+ readability.
+
+ - compatible: Specifies the compatibility list for the PIC. The type
+ shall be <string> and the value shall include "open-pic".
+
+ - reg: Specifies the base physical address(s) and size(s) of this
+ PIC's addressable register space. The type shall be <prop-encoded-array>.
+
+ - interrupt-controller: The presence of this property identifies the node
+ as an Open PIC. No property value shall be defined.
+
+ - #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt source. The type shall be a <u32> and the value shall be 2.
+
+ - #address-cells: Specifies the number of cells needed to encode an
+ address. The type shall be <u32> and the value shall be 0. As such,
+ 'interrupt-map' nodes do not have to specify a parent unit address.
+
+Optional properties:
+
+ - pic-no-reset: The presence of this property indicates that the PIC
+ shall not be reset during runtime initialization. No property value shall
+ be defined. The presence of this property also mandates that any
+ initialization related to interrupt sources shall be limited to sources
+ explicitly referenced in the device tree.
+
+* Interrupt Specifier Definition
+
+ Interrupt specifiers consists of 2 cells encoded as
+ follows:
+
+ - <1st-cell>: The interrupt-number that identifies the interrupt source.
+
+ - <2nd-cell>: The level-sense information, encoded as follows:
+ 0 = low-to-high edge triggered
+ 1 = active low level-sensitive
+ 2 = active high level-sensitive
+ 3 = high-to-low edge triggered
+
+* Examples
+
+Example 1:
+
+ /*
+ * An Open PIC interrupt controller
+ */
+ mpic: pic@40000 {
+ // This is an interrupt controller node.
+ interrupt-controller;
+
+ // No address cells so that 'interrupt-map' nodes which reference
+ // this Open PIC node do not need a parent address specifier.
+ #address-cells = <0>;
+
+ // Two cells to encode interrupt sources.
+ #interrupt-cells = <2>;
+
+ // Offset address of 0x40000 and size of 0x40000.
+ reg = <0x40000 0x40000>;
+
+ // Compatible with Open PIC.
+ compatible = "open-pic";
+
+ // The PIC shall not be reset.
+ pic-no-reset;
+ };
+
+Example 2:
+
+ /*
+ * An interrupt generating device that is wired to an Open PIC.
+ */
+ serial0: serial@4500 {
+ // Interrupt source '42' that is active high level-sensitive.
+ // Note that there are only two cells as specified in the interrupt
+ // parent's '#interrupt-cells' property.
+ interrupts = <42 2>;
+
+ // The interrupt controller that this device is wired to.
+ interrupt-parent = <&mpic>;

-Why: There are some drivers still using V4L1 API, despite all efforts we've done
- to migrate. Those drivers are for obsolete hardware that the old maintainer
- didn't care (or not have the hardware anymore), and that no other developer
- could find any hardware to buy. They probably have no practical usage today,
- and people with such old hardware could probably keep using an older version
- of the kernel. Those drivers will be moved to staging on 2.6.38 and, if nobody

-What: Video4Linux: Remove obsolete ioctl's
-When: kernel 2.6.39
-Files: include/media/videodev2.h
-Why: Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
- type of R/W arguments. They were fixed, but the old ioctl names are
- still there, maintained to avoid breaking binary compatibility:
- #define VIDIOC_OVERLAY_OLD _IOWR('V', 14, int)
- #define VIDIOC_S_PARM_OLD _IOW('V', 22, struct v4l2_streamparm)
- #define VIDIOC_S_CTRL_OLD _IOW('V', 28, struct v4l2_control)
- #define VIDIOC_G_AUDIO_OLD _IOWR('V', 33, struct v4l2_audio)
- #define VIDIOC_G_AUDOUT_OLD _IOWR('V', 49, struct v4l2_audioout)
- #define VIDIOC_CROPCAP_OLD _IOR('V', 58, struct v4l2_cropcap)
- There's no sense on preserving those forever, as it is very doubtful
- that someone would try to use a such old binary with a modern kernel.
- Removing them will allow us to remove some magic done at the V4L ioctl
- handler.

+dioread_lock Controls whether or not ext4 should use the DIO read
+dioread_nolock locking. If the dioread_nolock option is specified
+ ext4 will allocate uninitialized extent before buffer
+ write and convert the extent to initialized after IO
+ completes. This approach allows ext4 code to avoid
+ using inode mutex, which improves scalability on high
+ speed storages. However this does not work with nobh
+ option and the mount will fail. Nor does it work with
+ data journaling and dioread_nolock option will be
+ ignored with kernel warning. Note that dioread_nolock

+Ioctls
+======
+
+There is some Ext4 specific functionality which can be accessed by applications
+through the system call interfaces. The list of all Ext4 specific ioctls are
+shown in the table below.
+
+Table of Ext4 specific ioctls
+..............................................................................
+ Ioctl Description
+ EXT4_IOC_GETFLAGS Get additional attributes associated with inode.
+ The ioctl argument is an integer bitfield, with
+ bit values described in ext4.h. This ioctl is an
+ alias for FS_IOC_GETFLAGS.
+
+ EXT4_IOC_SETFLAGS Set additional attributes associated with inode.
+ The ioctl argument is an integer bitfield, with
+ bit values described in ext4.h. This ioctl is an
+ alias for FS_IOC_SETFLAGS.
+
+ EXT4_IOC_GETVERSION
+ EXT4_IOC_GETVERSION_OLD
+ Get the inode i_generation number stored for
+ each inode. The i_generation number is normally
+ changed only when new inode is created and it is
+ particularly useful for network filesystems. The
+ '_OLD' version of this ioctl is an alias for
+ FS_IOC_GETVERSION.
+
+ EXT4_IOC_SETVERSION
+ EXT4_IOC_SETVERSION_OLD
+ Set the inode i_generation number stored for
+ each inode. The '_OLD' version of this ioctl
+ is an alias for FS_IOC_SETVERSION.
+
+ EXT4_IOC_GROUP_EXTEND This ioctl has the same purpose as the resize
+ mount option. It allows to resize filesystem
+ to the end of the last existing block group,
+ further resize has to be done with resize2fs,
+ either online, or offline. The argument points
+ to the unsigned logn number representing the
+ filesystem new block count.
+
+ EXT4_IOC_MOVE_EXT Move the block extents from orig_fd (the one
+ this ioctl is pointing to) to the donor_fd (the
+ one specified in move_extent structure passed
+ as an argument to this ioctl). Then, exchange
+ inode metadata between orig_fd and donor_fd.
+ This is especially useful for online
+ defragmentation, because the allocator has the
+ opportunity to allocate moved blocks better,
+ ideally into one contiguous extent.
+
+ EXT4_IOC_GROUP_ADD Add a new group descriptor to an existing or
+ new group descriptor block. The new group
+ descriptor is described by ext4_new_group_input
+ structure, which is passed as an argument to
+ this ioctl. This is especially useful in
+ conjunction with EXT4_IOC_GROUP_EXTEND,
+ which allows online resize of the filesystem
+ to the end of the last existing block group.
+ Those two ioctls combined is used in userspace
+ online resize tool (e.g. resize2fs).
+
+ EXT4_IOC_MIGRATE This ioctl operates on the filesystem itself.
+ It converts (migrates) ext3 indirect block mapped
+ inode to ext4 extent mapped inode by walking
+ through indirect block mapping of the original
+ inode and converting contiguous block ranges
+ into ext4 extents of the temporary inode. Then,
+ inodes are swapped. This ioctl might help, when
+ migrating from ext3 to ext4 filesystem, however
+ suggestion is to create fresh ext4 filesystem
+ and copy data from the backup. Note, that
+ filesystem has to support extents for this ioctl
+ to work.
+
+ EXT4_IOC_ALLOC_DA_BLKS Force all of the delay allocated blocks to be
+ allocated to preserve application-expected ext3
+ behaviour. Note that this will also start
+ triggering a write of the data blocks, but this
+ behaviour may change in the future as it is
+ not necessary and has been done this way only
+ for sake of simplicity.

+Kernel driver ads1015
+=====================
+
+Supported chips:
+ * Texas Instruments ADS1015
+ Prefix: 'ads1015'
+ Datasheet: Publicly available at the Texas Instruments website :

+Authors:
+ Dirk Eibach, Guntermann & Drunck GmbH <eibach@gdsys.de>
+
+Description
+-----------
+
+This driver implements support for the Texas Instruments ADS1015.
+
+This device is a 12-bit A-D converter with 4 inputs.
+
+The inputs can be used single ended or in certain differential combinations.
+
+The inputs can be made available by 8 sysfs input files in0_input - in7_input:
+in0: Voltage over AIN0 and AIN1.
+in1: Voltage over AIN0 and AIN3.
+in2: Voltage over AIN1 and AIN3.
+in3: Voltage over AIN2 and AIN3.
+in4: Voltage over AIN0 and GND.
+in5: Voltage over AIN1 and GND.
+in6: Voltage over AIN2 and GND.
+in7: Voltage over AIN3 and GND.
+
+Which inputs are available can be configured using platform data or devicetree.
+
+By default all inputs are exported.
+
+Platform Data
+-------------
+
+In linux/i2c/ads1015.h platform data is defined, channel_data contains
+configuration data for the used input combinations:
+- pga is the programmable gain amplifier (values are full scale)
+ 0: +/- 6.144 V
+ 1: +/- 4.096 V
+ 2: +/- 2.048 V
+ 3: +/- 1.024 V
+ 4: +/- 0.512 V
+ 5: +/- 0.256 V
+- data_rate in samples per second
+ 0: 128
+ 1: 250
+ 2: 490
+ 3: 920
+ 4: 1600
+ 5: 2400
+ 6: 3300
+
+Example:
+struct ads1015_platform_data data = {
+ .channel_data = {
+ [2] = { .enabled = true, .pga = 1, .data_rate = 0 },
+ [4] = { .enabled = true, .pga = 4, .data_rate = 5 },
+ }
+};
+
+In this case only in2_input (FS +/- 4.096 V, 128 SPS) and in4_input
+(FS +/- 0.512 V, 2400 SPS) would be created.
+
+Devicetree

+Configuration is also possible via devicetree:

+Linux kernel media framework
+============================
+
+This document describes the Linux kernel media framework, its data structures,
+functions and their usage.
+
+
+Introduction
+------------
+
+The media controller API is documented in DocBook format in
+Documentation/DocBook/v4l/media-controller.xml. This document will focus on
+the kernel-side implementation of the media framework.
+
+
+Abstract media device model
+---------------------------
+
+Discovering a device internal topology, and configuring it at runtime, is one
+of the goals of the media framework. To achieve this, hardware devices are
+modeled as an oriented graph of building blocks called entities connected
+through pads.
+
+An entity is a basic media hardware building block. It can correspond to
+a large variety of logical blocks such as physical hardware devices
+(CMOS sensor for instance), logical hardware devices (a building block
+in a System-on-Chip image processing pipeline), DMA channels or physical
+connectors.
+
+A pad is a connection endpoint through which an entity can interact with
+other entities. Data (not restricted to video) produced by an entity
+flows from the entity's output to one or more entity inputs. Pads should
+not be confused with physical pins at chip boundaries.
+
+A link is a point-to-point oriented connection between two pads, either
+on the same entity or on different entities. Data flows from a source
+pad to a sink pad.
+
+
+Media device
+------------
+
+A media device is represented by a struct media_device instance, defined in
+include/media/media-device.h. Allocation of the structure is handled by the
+media device driver, usually by embedding the media_device instance in a
+larger driver-specific structure.
+
+Drivers register media device instances by calling
+
+ media_device_register(struct media_device *mdev);
+
+The caller is responsible for initializing the media_device structure before
+registration. The following fields must be set:
+
+ - dev must point to the parent device (usually a pci_dev, usb_interface or
+ platform_device instance).
+
+ - model must be filled with the device model name as a NUL-terminated UTF-8
+ string. The device/model revision must not be stored in this field.
+
+The following fields are optional:
+
+ - serial is a unique serial number stored as a NUL-terminated ASCII string.
+ The field is big enough to store a GUID in text form. If the hardware
+ doesn't provide a unique serial number this field must be left empty.
+
+ - bus_info represents the location of the device in the system as a
+ NUL-terminated ASCII string. For PCI/PCIe devices bus_info must be set to
+ "PCI:" (or "PCIe:") followed by the value of pci_name(). For USB devices,
+ the usb_make_path() function must be used. This field is used by
+ applications to distinguish between otherwise identical devices that don't
+ provide a serial number.
+
+ - hw_revision is the hardware device revision in a driver-specific format.
+ When possible the revision should be formatted with the KERNEL_VERSION
+ macro.
+
+ - driver_version is formatted with the KERNEL_VERSION macro. The version
+ minor must be incremented when new features are added to the userspace API
+ without breaking binary compatibility. The version major must be
+ incremented when binary compatibility is broken.
+
+Upon successful registration a character device named media[0-9]+ is created.
+The device major and minor numbers are dynamic. The model name is exported as
+a sysfs attribute.
+
+Drivers unregister media device instances by calling
+
+ media_device_unregister(struct media_device *mdev);
+
+Unregistering a media device that hasn't been registered is *NOT* safe.
+
+
+Entities, pads and links
+------------------------
+
+- Entities
+
+Entities are represented by a struct media_entity instance, defined in
+include/media/media-entity.h. The structure is usually embedded into a
+higher-level structure, such as a v4l2_subdev or video_device instance,
+although drivers can allocate entities directly.
+
+Drivers initialize entities by calling
+
+ media_entity_init(struct media_entity *entity, u16 num_pads,
+ struct media_pad *pads, u16 extra_links);
+
+The media_entity name, type, flags, revision and group_id fields can be
+initialized before or after calling media_entity_init. Entities embedded in
+higher-level standard structures can have some of those fields set by the
+higher-level framework.
+
+As the number of pads is known in advance, the pads array is not allocated
+dynamically but is managed by the entity driver. Most drivers will embed the
+pads array in a driver-specific structure, avoiding dynamic allocation.
+
+Drivers must set the direction of every pad in the pads array before calling
+media_entity_init. The function will initialize the other pads fields.
+
+Unlike the number of pads, the total number of links isn't always known in
+advance by the entity driver. As an initial estimate, media_entity_init
+pre-allocates a number of links equal to the number of pads plus an optional
+number of extra links. The links array will be reallocated if it grows beyond
+the initial estimate.
+
+Drivers register entities with a media device by calling
+
+ media_device_register_entity(struct media_device *mdev,
+ struct media_entity *entity);
+
+Entities are identified by a unique positive integer ID. Drivers can provide an
+ID by filling the media_entity id field prior to registration, or request the
+media controller framework to assign an ID automatically. Drivers that provide
+IDs manually must ensure that all IDs are unique. IDs are not guaranteed to be
+contiguous even when they are all assigned automatically by the framework.
+
+Drivers unregister entities by calling
+
+ media_device_unregister_entity(struct media_entity *entity);
+
+Unregistering an entity will not change the IDs of the other entities, and the
+ID will never be reused for a newly registered entity.
+
+When a media device is unregistered, all its entities are unregistered
+automatically. No manual entities unregistration is then required.
+
+Drivers free resources associated with an entity by calling
+
+ media_entity_cleanup(struct media_entity *entity);
+
+This function must be called during the cleanup phase after unregistering the
+entity. Note that the media_entity instance itself must be freed explicitly by
+the driver if required.
+
+Entities have flags that describe the entity capabilities and state.
+
+ MEDIA_ENT_FL_DEFAULT indicates the default entity for a given type.
+ This can be used to report the default audio and video devices or the
+ default camera sensor.
+
+Logical entity groups can be defined by setting the group ID of all member
+entities to the same non-zero value. An entity group serves no purpose in the
+kernel, but is reported to userspace during entities enumeration. The group_id
+field belongs to the media device driver and must not by touched by entity
+drivers.
+
+Media device drivers should define groups if several entities are logically
+bound together. Example usages include reporting
+
+ - ALSA, VBI and video nodes that carry the same media stream
+ - lens and flash controllers associated with a sensor
+
+- Pads
+
+Pads are represented by a struct media_pad instance, defined in
+include/media/media-entity.h. Each entity stores its pads in a pads array
+managed by the entity driver. Drivers usually embed the array in a
+driver-specific structure.
+
+Pads are identified by their entity and their 0-based index in the pads array.
+Both information are stored in the media_pad structure, making the media_pad
+pointer the canonical way to store and pass link references.
+
+Pads have flags that describe the pad capabilities and state.
+
+ MEDIA_PAD_FL_SINK indicates that the pad supports sinking data.
+ MEDIA_PAD_FL_SOURCE indicates that the pad supports sourcing data.
+
+One and only one of MEDIA_PAD_FL_SINK and MEDIA_PAD_FL_SOURCE must be set for
+each pad.
+
+- Links
+
+Links are represented by a struct media_link instance, defined in
+include/media/media-entity.h. Each entity stores all links originating at or
+targetting any of its pads in a links array. A given link is thus stored
+twice, once in the source entity and once in the target entity. The array is
+pre-allocated and grows dynamically as needed.
+
+Drivers create links by calling
+
+ media_entity_create_link(struct media_entity *source, u16 source_pad,
+ struct media_entity *sink, u16 sink_pad,
+ u32 flags);
+
+An entry in the link array of each entity is allocated and stores pointers
+to source and sink pads.
+
+Links have flags that describe the link capabilities and state.
+
+ MEDIA_LNK_FL_ENABLED indicates that the link is enabled and can be used
+ to transfer media data. When two or more links target a sink pad, only
+ one of them can be enabled at a time.
+ MEDIA_LNK_FL_IMMUTABLE indicates that the link enabled state can't be
+ modified at runtime. If MEDIA_LNK_FL_IMMUTABLE is set, then
+ MEDIA_LNK_FL_ENABLED must also be set since an immutable link is always
+ enabled.
+
+
+Graph traversal
+---------------
+
+The media framework provides APIs to iterate over entities in a graph.
+
+To iterate over all entities belonging to a media device, drivers can use the
+media_device_for_each_entity macro, defined in include/media/media-device.h.
+
+ struct media_entity *entity;
+
+ media_device_for_each_entity(entity, mdev) {
+ /* entity will point to each entity in turn */
+ ...
+ }
+
+Drivers might also need to iterate over all entities in a graph that can be
+reached only through enabled links starting at a given entity. The media
+framework provides a depth-first graph traversal API for that purpose.
+
+Note that graphs with cycles (whether directed or undirected) are *NOT*
+supported by the graph traversal API. To prevent infinite loops, the graph
+traversal code limits the maximum depth to MEDIA_ENTITY_ENUM_MAX_DEPTH,
+currently defined as 16.
+
+Drivers initiate a graph traversal by calling
+
+ media_entity_graph_walk_start(struct media_entity_graph *graph,
+ struct media_entity *entity);
+
+The graph structure, provided by the caller, is initialized to start graph
+traversal at the given entity.
+
+Drivers can then retrieve the next entity by calling
+
+ media_entity_graph_walk_next(struct media_entity_graph *graph);
+
+When the graph traversal is complete the function will return NULL.
+
+Graph traversal can be interrupted at any moment. No cleanup function call is
+required and the graph structure can be freed normally.
+
+Helper functions can be used to find a link between two given pads, or a pad
+connected to another pad through an enabled link
+
+ media_entity_find_link(struct media_pad *source,
+ struct media_pad *sink);
+
+ media_entity_remote_source(struct media_pad *pad);
+
+Refer to the kerneldoc documentation for more information.
+
+
+Use count and power handling
+----------------------------
+
+Due to the wide differences between drivers regarding power management needs,
+the media controller does not implement power management. However, the
+media_entity structure includes a use_count field that media drivers can use to
+track the number of users of every entity for power management needs.
+
+The use_count field is owned by media drivers and must not be touched by entity
+drivers. Access to the field must be protected by the media device graph_mutex
+lock.
+
+
+Links setup
+-----------
+
+Link properties can be modified at runtime by calling
+
+ media_entity_setup_link(struct media_link *link, u32 flags);
+
+The flags argument contains the requested new link flags.
+
+The only configurable property is the ENABLED link flag to enable/disable a
+link. Links marked with the IMMUTABLE link flag can not be enabled or disabled.
+
+When a link is enabled or disabled, the media framework calls the
+link_setup operation for the two entities at the source and sink of the link,
+in that order. If the second link_setup call fails, another link_setup call is
+made on the first entity to restore the original link flags.
+
+Media device drivers can be notified of link setup operations by setting the
+media_device::link_notify pointer to a callback function. If provided, the
+notification callback will be called before enabling and after disabling
+links.
+
+Entity drivers must implement the link_setup operation if any of their links
+is non-immutable. The operation must either configure the hardware or store
+the configuration information to be applied later.
+
+Link configuration must not have any side effect on other links. If an enabled
+link at a sink pad prevents another link at the same pad from being disabled,
+the link_setup operation must return -EBUSY and can't implicitly disable the
+first enabled link.
+
+
+Pipelines and media streams
+---------------------------
+
+When starting streaming, drivers must notify all entities in the pipeline to
+prevent link states from being modified during streaming by calling
+
+ media_entity_pipeline_start(struct media_entity *entity,
+ struct media_pipeline *pipe);
+
+The function will mark all entities connected to the given entity through
+enabled links, either directly or indirectly, as streaming.
+
+The media_pipeline instance pointed to by the pipe argument will be stored in
+every entity in the pipeline. Drivers should embed the media_pipeline structure
+in higher-level pipeline structures and can then access the pipeline through
+the media_entity pipe field.
+
+Calls to media_entity_pipeline_start() can be nested. The pipeline pointer must
+be identical for all nested calls to the function.
+
+When stopping the stream, drivers must notify the entities with
+
+ media_entity_pipeline_stop(struct media_entity *entity);
+
+If multiple calls to media_entity_pipeline_start() have been made the same
+number of media_entity_pipeline_stop() calls are required to stop streaming. The
+media_entity pipe field is reset to NULL on the last nested stop call.
+
+Link configuration will fail with -EBUSY by default if either end of the link is
+a streaming entity. Links that can be modified while streaming must be marked
+with the MEDIA_LNK_FL_DYNAMIC flag.
+
+If other operations need to be disallowed on streaming entities (such as
+changing entities configuration parameters) drivers can explictly check the
+media_entity stream_count field to find out if an entity is streaming. This
+operation must be done with the media_device graph_mutex held.

+ PCIe gadget support for SPEAr13XX platform
+purpose
+===========
+This driver has several nodes which can be read/written by configfs interface.
+Its main purpose is to configure selected dual mode PCIe controller as device
+and then program its various registers to configure it as a particular device
+type. This driver can be used to show spear's PCIe device capability.
+
+Description of different nodes:
+=================================
+
+read behavior of nodes:
+------------------------------
+link :gives ltssm status.
+int_type :type of supported interrupt
+no_of_msi :zero if MSI is not enabled by host. A positive value is the
+ number of MSI vector granted.
+vendor_id :returns programmed vendor id (hex)
+device_id :returns programmed device id(hex)
+bar0_size: :returns size of bar0 in hex.
+bar0_address :returns address of bar0 mapped area in hex.
+bar0_rw_offset :returns offset of bar0 for which bar0_data will return value.
+bar0_data :returns data at bar0_rw_offset.
+
+write behavior of nodes:
+------------------------------
+link :write UP to enable ltsmm DOWN to disable
+int_type :write interrupt type to be configured and (int_type could be
+ INTA, MSI or NO_INT). Select MSI only when you have programmed
+ no_of_msi node.
+no_of_msi :number of MSI vector needed.
+inta :write 1 to assert INTA and 0 to de-assert.
+send_msi :write MSI vector to be sent.
+vendor_id :write vendor id(hex) to be programmed.
+device_id :write device id(hex) to be programmed.
+bar0_size :write size of bar0 in hex. default bar0 size is 1000 (hex)
+ bytes.
+bar0_address :write address of bar0 mapped area in hex. (default mapping of
+ bar0 is SYSRAM1(E0800000). Always program bar size before bar
+ address. Kernel might modify bar size and address for alignment, so
+ read back bar size and address after writing to cross check.
+bar0_rw_offset :write offset of bar0 for which bar0_data will write value.
+bar0_data :write data to be written at bar0_rw_offset.
+
+Node programming example
+===========================
+Program all PCIe registers in such a way that when this device is connected
+to the PCIe host, then host sees this device as 1MB RAM.
+#mount -t configfs none /Config
+For nth PCIe Device Controller
+# cd /config/pcie_gadget.n/
+Now you have all the nodes in this directory.
+program vendor id as 0x104a
+# echo 104A >> vendor_id
+
+program device id as 0xCD80
+# echo CD80 >> device_id
+
+program BAR0 size as 1MB
+# echo 100000 >> bar0_size
+
+check for programmed bar0 size
+# cat bar0_size
+
+Program BAR0 Address as DDR (0x2100000). This is the physical address of
+memory, which is to be made visible to PCIe host. Similarly any other peripheral
+can also be made visible to PCIe host. E.g., if you program base address of UART
+as BAR0 address then when this device will be connected to a host, it will be
+visible as UART.
+# echo 2100000 >> bar0_address
+
+program interrupt type : INTA
+# echo INTA >> int_type
+
+go for link up now.
+# echo UP >> link
+
+It will have to be insured that, once link up is done on gadget, then only host
+is initialized and start to search PCIe devices on its port.
+
+/*wait till link is up*/
+# cat link
+wait till it returns UP.
+
+To assert INTA
+# echo 1 >> inta
+
+To de-assert INTA
+# echo 0 >> inta
+
+if MSI is to be used as interrupt, program no of msi vector needed (say4)
+# echo 4 >> no_of_msi
+
+select MSI as interrupt type
+# echo MSI >> int_type
+
+go for link up now
+# echo UP >> link
+
+wait till link is up
+# cat link
+An application can repetitively read this node till link is found UP. It can
+sleep between two read.
+
+wait till msi is enabled
+# cat no_of_msi
+Should return 4 (number of requested MSI vector)
+
+to send msi vector 2

+ The Linux RapidIO Subsystem
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The RapidIO standard is a packet-based fabric interconnect standard designed for
+use in embedded systems. Development of the RapidIO standard is directed by the
+RapidIO Trade Association (RTA). The current version of the RapidIO specification
+is publicly available for download from the RTA web-site [1].
+
+This document describes the basics of the Linux RapidIO subsystem and provides
+information on its major components.
+
+1 Overview
+----------
+
+Because the RapidIO subsystem follows the Linux device model it is integrated
+into the kernel similarly to other buses by defining RapidIO-specific device and
+bus types and registering them within the device model.
+
+The Linux RapidIO subsystem is architecture independent and therefore defines
+architecture-specific interfaces that provide support for common RapidIO
+subsystem operations.
+
+2. Core Components
+------------------
+
+A typical RapidIO network is a combination of endpoints and switches.
+Each of these components is represented in the subsystem by an associated data
+structure. The core logical components of the RapidIO subsystem are defined
+in include/linux/rio.h file.
+
+2.1 Master Port
+
+A master port (or mport) is a RapidIO interface controller that is local to the
+processor executing the Linux code. A master port generates and receives RapidIO
+packets (transactions). In the RapidIO subsystem each master port is represented
+by a rio_mport data structure. This structure contains master port specific
+resources such as mailboxes and doorbells. The rio_mport also includes a unique
+host device ID that is valid when a master port is configured as an enumerating
+host.
+
+RapidIO master ports are serviced by subsystem specific mport device drivers
+that provide functionality defined for this subsystem. To provide a hardware
+independent interface for RapidIO subsystem operations, rio_mport structure
+includes rio_ops data structure which contains pointers to hardware specific
+implementations of RapidIO functions.
+
+2.2 Device
+
+A RapidIO device is any endpoint (other than mport) or switch in the network.
+All devices are presented in the RapidIO subsystem by corresponding rio_dev data
+structure. Devices form one global device list and per-network device lists
+(depending on number of available mports and networks).
+
+2.3 Switch
+
+A RapidIO switch is a special class of device that routes packets between its
+ports towards their final destination. The packet destination port within a
+switch is defined by an internal routing table. A switch is presented in the
+RapidIO subsystem by rio_dev data structure expanded by additional rio_switch
+data structure, which contains switch specific information such as copy of the
+routing table and pointers to switch specific functions.
+
+The RapidIO subsystem defines the format and initialization method for subsystem
+specific switch drivers that are designed to provide hardware-specific
+implementation of common switch management routines.
+
+2.4 Network
+
+A RapidIO network is a combination of interconnected endpoint and switch devices.
+Each RapidIO network known to the system is represented by corresponding rio_net
+data structure. This structure includes lists of all devices and local master
+ports that form the same network. It also contains a pointer to the default
+master port that is used to communicate with devices within the network.
+
+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
+rio_register_mport() for each available master port. After all active master
+ports are registered with a RapidIO subsystem, the rio_init_mports() routine
+is called to perform enumeration and discovery.
+
+In the current PowerPC-based implementation a subsys_initcall() is specified to
+perform controller initialization and mport registration. At the end it directly
+calls rio_init_mports() to execute RapidIO enumeration and discovery.
+
+4. Enumeration and Discovery
+----------------------------
+
+When rio_init_mports() is called it scans a list of registered master ports and
+calls an enumeration or discovery routine depending on the configured role of a
+master port: host or agent.
+
+Enumeration is performed by a master port if it is configured as a host port by
+assigning a host device ID greater than or equal to zero. A host device ID is
+assigned to a master port through the kernel command line parameter "riohdid=",
+or can be configured in a platform-specific manner. 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.
+
+The enumeration process is implemented according to the enumeration algorithm
+outlined in the RapidIO Interconnect Specification: Annex I [1].
+
+The enumeration process traverses the network using a recursive depth-first
+algorithm. When a new device is found, the enumerator takes ownership of that
+device by writing into the Host Device ID Lock CSR. It does this to ensure that
+the enumerator has exclusive right to enumerate the device. If device ownership
+is successfully acquired, the enumerator allocates a new rio_dev structure and
+initializes it according to device capabilities.
+
+If the device is an endpoint, a unique device ID is assigned to it and its value
+is written into the device's Base Device ID CSR.
+
+If the device is a switch, the enumerator allocates an additional rio_switch
+structure to store switch specific information. Then the switch's vendor ID and
+device ID are queried against a table of known RapidIO switches. Each switch
+table entry contains a pointer to a switch-specific initialization routine that
+initializes pointers to the rest of switch specific operations, and performs
+hardware initialization if necessary. A RapidIO switch does not have a unique
+device ID; it relies on hopcount and routing for device ID of an attached
+endpoint if access to its configuration registers is required. If a switch (or
+chain of switches) does not have any endpoint (except enumerator) attached to
+it, a fake device ID will be assigned to configure a route to that switch.
+In the case of a chain of switches without endpoint, one fake device ID is used
+to configure a route through the entire chain and switches are differentiated by
+their hopcount value.
+
+For both endpoints and switches the enumerator writes a unique component tag
+into device's Component Tag CSR. That unique value is used by the error
+management notification mechanism to identify a device that is reporting an
+error management event.
+
+Enumeration beyond a switch is completed by iterating over each active egress
+port of that switch. For each active link, a route to a default device ID
+(0xFF for 8-bit systems and 0xFFFF for 16-bit systems) is temporarily written
+into the routing table. The algorithm recurs by calling itself with hopcount + 1
+and the default device ID in order to access the device on the active port.
+
+After the host has completed enumeration of the entire network it releases
+devices by clearing device ID locks (calls rio_clear_locks()). For each endpoint
+in the system, it sets the Master Enable bit in the Port General Control CSR
+to indicate that enumeration is completed and agents are allowed to execute
+passive discovery of the network.
+
+The discovery process is performed by agents and is similar to the enumeration
+process that is described above. However, the discovery process is performed
+without changes to the existing routing because agents only gather information
+about RapidIO network structure and are building an internal map of discovered
+devices. This way each Linux-based component of the RapidIO subsystem has
+a complete view of the network. The discovery process can be performed
+simultaneously by several agents. After initializing its RapidIO master port
+each agent waits for enumeration completion by the host for the configured wait
+time period. If this wait time period expires before enumeration is completed,
+an agent skips RapidIO discovery and continues with remaining kernel
+initialization.

+ RapidIO sysfs Files
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1. Device Subdirectories
+------------------------
+
+For each RapidIO device, the RapidIO subsystem creates files in an individual
+subdirectory with the following name, /sys/bus/rapidio/devices/<device_name>.
+
+The format of device_name is "nn:d:iiii", where:
+
+nn - two-digit hexadecimal ID of RapidIO network where the device resides
+d - device typr: 'e' - for endpoint or 's' - for switch
+iiii - four-digit device destID for endpoints, or switchID for switches
+
+For example, below is a list of device directories that represents a typical
+RapidIO network with one switch, one host, and two agent endpoints, as it is
+seen by the enumerating host (destID = 1):
+
+/sys/bus/rapidio/devices/00:e:0000
+/sys/bus/rapidio/devices/00:e:0002
+/sys/bus/rapidio/devices/00:s:0001
+
+NOTE: An enumerating or discovering endpoint does not create a sysfs entry for
+itself, this is why an endpoint with destID=1 is not shown in the list.
+
+2. Attributes Common for All Devices
+------------------------------------
+
+Each device subdirectory contains the following informational read-only files:
+
+ did - returns the device identifier
+ vid - returns the device vendor identifier
+device_rev - returns the device revision level
+ asm_did - returns identifier for the assembly containing the device
+ asm_rev - returns revision level of the assembly containing the device
+ asm_vid - returns vendor identifier of the assembly containing the device
+ destid - returns device destination ID assigned by the enumeration routine
+ (see 4.1 for switch specific details)
+ lprev - returns name of previous device (switch) on the path to the device
+ that that owns this attribute
+
+In addition to the files listed above, each device has a binary attribute file
+that allows read/write access to the device configuration registers using
+the RapidIO maintenance transactions:
+
+ config - reads from and writes to the device configuration registers.
+
+This attribute is similar in behavior to the "config" attribute of PCI devices
+and provides an access to the RapidIO device registers using standard file read
+and write operations.
+
+3. Endpoint Device Attributes
+-----------------------------
+
+Currently Linux RapidIO subsystem does not create any endpoint specific sysfs
+attributes. It is possible that RapidIO master port drivers and endpoint device
+drivers will add their device-specific sysfs attributes but such attributes are
+outside the scope of this document.
+
+4. Switch Device Attributes
+---------------------------
+
+RapidIO switches have additional attributes in sysfs. RapidIO subsystem supports
+common and device-specific sysfs attributes for switches. Because switches are
+integrated into the RapidIO subsystem, it offers a method to create
+device-specific sysfs attributes by specifying a callback function that may be
+set by the switch initialization routine during enumeration or discovery process.
+
+4.1 Common Switch Attributes
+
+ routes - reports switch routing information in "destID port" format. This
+ attribute reports only valid routing table entries, one line for
+ each entry.
+ destid - device destination ID that defines a route to the switch
+ hopcount - number of hops on the path to the switch
+ lnext - returns names of devices linked to the switch except one of a device
+ linked to the ingress port (reported as "lprev"). This is an array
+ names with number of lines equal to number of ports in switch. If
+ a switch port has no attached device, returns "null" instead of
+ a device name.
+
+4.2 Device-specific Switch Attributes
+
+Device-specific switch attributes are listed for each RapidIO switch driver
+that exports additional attributes.
+
+IDT_GEN2:
+ errlog - reads contents of device error log until it is empty.

+Introduction
+============
+
+This file documents the Texas Instruments OMAP 3 Image Signal Processor (ISP)
+driver located under drivers/media/video/omap3isp. The original driver was
+written by Texas Instruments but since that it has been rewritten (twice) at
+Nokia.
+
+The driver has been successfully used on the following versions of OMAP 3:
+
+ 3430
+ 3530
+ 3630
+
+The driver implements V4L2, Media controller and v4l2_subdev interfaces.
+Sensor, lens and flash drivers using the v4l2_subdev interface in the kernel
+are supported.
+
+
+Split to subdevs
+================
+
+The OMAP 3 ISP is split into V4L2 subdevs, each of the blocks inside the ISP
+having one subdev to represent it. Each of the subdevs provide a V4L2 subdev
+interface to userspace.
+
+ OMAP3 ISP CCP2
+ OMAP3 ISP CSI2a
+ OMAP3 ISP CCDC
+ OMAP3 ISP preview
+ OMAP3 ISP resizer
+ OMAP3 ISP AEWB
+ OMAP3 ISP AF
+ OMAP3 ISP histogram
+
+Each possible link in the ISP is modelled by a link in the Media controller
+interface. For an example program see [2].
+
+
+Controlling the OMAP 3 ISP
+==========================
+
+In general, the settings given to the OMAP 3 ISP take effect at the beginning
+of the following frame. This is done when the module becomes idle during the
+vertical blanking period on the sensor. In memory-to-memory operation the pipe
+is run one frame at a time. Applying the settings is done between the frames.
+
+All the blocks in the ISP, excluding the CSI-2 and possibly the CCP2 receiver,
+insist on receiving complete frames. Sensors must thus never send the ISP
+partial frames.
+
+Autoidle does have issues with some ISP blocks on the 3430, at least.
+Autoidle is only enabled on 3630 when the omap3isp module parameter autoidle
+is non-zero.
+
+
+Events
+======
+
+The OMAP 3 ISP driver does support the V4L2 event interface on CCDC and
+statistics (AEWB, AF and histogram) subdevs.
+
+The CCDC subdev produces V4L2_EVENT_OMAP3ISP_HS_VS type event on HS_VS
+interrupt which is used to signal frame start. The event is triggered exactly
+when the reception of the first line of the frame starts in the CCDC module.
+The event can be subscribed on the CCDC subdev.
+
+(When using parallel interface one must pay account to correct configuration
+of the VS signal polarity. This is automatically correct when using the serial
+receivers.)
+
+Each of the statistics subdevs is able to produce events. An event is
+generated whenever a statistics buffer can be dequeued by a user space
+application using the VIDIOC_OMAP3ISP_STAT_REQ IOCTL. The events available
+are:
+
+ V4L2_EVENT_OMAP3ISP_AEWB
+ V4L2_EVENT_OMAP3ISP_AF
+ V4L2_EVENT_OMAP3ISP_HIST
+
+The type of the event data is struct omap3isp_stat_event_status for these
+ioctls. If there is an error calculating the statistics, there will be an
+event as usual, but no related statistics buffer. In this case
+omap3isp_stat_event_status.buf_err is set to non-zero.
+
+
+Private IOCTLs
+==============
+
+The OMAP 3 ISP driver supports standard V4L2 IOCTLs and controls where
+possible and practical. Much of the functions provided by the ISP, however,
+does not fall under the standard IOCTLs --- gamma tables and configuration of
+statistics collection are examples of such.
+
+In general, there is a private ioctl for configuring each of the blocks
+containing hardware-dependent functions.
+
+The following private IOCTLs are supported:
+
+ VIDIOC_OMAP3ISP_CCDC_CFG
+ VIDIOC_OMAP3ISP_PRV_CFG
+ VIDIOC_OMAP3ISP_AEWB_CFG
+ VIDIOC_OMAP3ISP_HIST_CFG
+ VIDIOC_OMAP3ISP_AF_CFG
+ VIDIOC_OMAP3ISP_STAT_REQ
+ VIDIOC_OMAP3ISP_STAT_EN
+
+The parameter structures used by these ioctls are described in
+include/linux/omap3isp.h. The detailed functions of the ISP itself related to
+a given ISP block is described in the Technical Reference Manuals (TRMs) ---
+see the end of the document for those.
+
+While it is possible to use the ISP driver without any use of these private
+IOCTLs it is not possible to obtain optimal image quality this way. The AEWB,
+AF and histogram modules cannot be used without configuring them using the
+appropriate private IOCTLs.
+
+
+CCDC and preview block IOCTLs
+=============================
+
+The VIDIOC_OMAP3ISP_CCDC_CFG and VIDIOC_OMAP3ISP_PRV_CFG IOCTLs are used to
+configure, enable and disable functions in the CCDC and preview blocks,
+respectively. Both IOCTLs control several functions in the blocks they
+control. VIDIOC_OMAP3ISP_CCDC_CFG IOCTL accepts a pointer to struct
+omap3isp_ccdc_update_config as its argument. Similarly VIDIOC_OMAP3ISP_PRV_CFG
+accepts a pointer to struct omap3isp_prev_update_config. The definition of
+both structures is available in [1].
+
+The update field in the structures tells whether to update the configuration
+for the specific function and the flag tells whether to enable or disable the
+function.
+
+The update and flag bit masks accept the following values. Each separate
+functions in the CCDC and preview blocks is associated with a flag (either
+disable or enable; part of the flag field in the structure) and a pointer to
+configuration data for the function.
+
+Valid values for the update and flag fields are listed here for
+VIDIOC_OMAP3ISP_CCDC_CFG. Values may be or'ed to configure more than one
+function in the same IOCTL call.
+
+ OMAP3ISP_CCDC_ALAW
+ OMAP3ISP_CCDC_LPF
+ OMAP3ISP_CCDC_BLCLAMP
+ OMAP3ISP_CCDC_BCOMP
+ OMAP3ISP_CCDC_FPC
+ OMAP3ISP_CCDC_CULL
+ OMAP3ISP_CCDC_CONFIG_LSC
+ OMAP3ISP_CCDC_TBL_LSC
+
+The corresponding values for the VIDIOC_OMAP3ISP_PRV_CFG are here:
+
+ OMAP3ISP_PREV_LUMAENH
+ OMAP3ISP_PREV_INVALAW
+ OMAP3ISP_PREV_HRZ_MED
+ OMAP3ISP_PREV_CFA
+ OMAP3ISP_PREV_CHROMA_SUPP
+ OMAP3ISP_PREV_WB
+ OMAP3ISP_PREV_BLKADJ
+ OMAP3ISP_PREV_RGB2RGB
+ OMAP3ISP_PREV_COLOR_CONV
+ OMAP3ISP_PREV_YC_LIMIT
+ OMAP3ISP_PREV_DEFECT_COR
+ OMAP3ISP_PREV_GAMMABYPASS
+ OMAP3ISP_PREV_DRK_FRM_CAPTURE
+ OMAP3ISP_PREV_DRK_FRM_SUBTRACT
+ OMAP3ISP_PREV_LENS_SHADING
+ OMAP3ISP_PREV_NF
+ OMAP3ISP_PREV_GAMMA
+
+The associated configuration pointer for the function may not be NULL when
+enabling the function. When disabling a function the configuration pointer is
+ignored.
+
+
+Statistic blocks IOCTLs
+=======================
+
+The statistics subdevs do offer more dynamic configuration options than the
+other subdevs. They can be enabled, disable and reconfigured when the pipeline
+is in streaming state.
+
+The statistics blocks always get the input image data from the CCDC (as the
+histogram memory read isn't implemented). The statistics are dequeueable by
+the user from the statistics subdev nodes using private IOCTLs.
+
+The private IOCTLs offered by the AEWB, AF and histogram subdevs are heavily
+reflected by the register level interface offered by the ISP hardware. There
+are aspects that are purely related to the driver implementation and these are
+discussed next.
+
+VIDIOC_OMAP3ISP_STAT_EN
+-----------------------
+
+This private IOCTL enables/disables a statistic module. If this request is
+done before streaming, it will take effect as soon as the pipeline starts to
+stream. If the pipeline is already streaming, it will take effect as soon as
+the CCDC becomes idle.
+
+VIDIOC_OMAP3ISP_AEWB_CFG, VIDIOC_OMAP3ISP_HIST_CFG and VIDIOC_OMAP3ISP_AF_CFG
+-----------------------------------------------------------------------------
+
+Those IOCTLs are used to configure the modules. They require user applications
+to have an in-depth knowledge of the hardware. Most of the fields explanation
+can be found on OMAP's TRMs. The two following fields common to all the above
+configure private IOCTLs require explanation for better understanding as they
+are not part of the TRM.
+
+omap3isp_[h3a_af/h3a_aewb/hist]_config.buf_size:
+
+The modules handle their buffers internally. The necessary buffer size for the
+module's data output depends on the requested configuration. Although the
+driver supports reconfiguration while streaming, it does not support a
+reconfiguration which requires bigger buffer size than what is already
+internally allocated if the module is enabled. It will return -EBUSY on this
+case. In order to avoid such condition, either disable/reconfigure/enable the
+module or request the necessary buffer size during the first configuration
+while the module is disabled.
+
+The internal buffer size allocation considers the requested configuration's
+minimum buffer size and the value set on buf_size field. If buf_size field is
+out of [minimum, maximum] buffer size range, it's clamped to fit in there.
+The driver then selects the biggest value. The corrected buf_size value is
+written back to user application.
+
+omap3isp_[h3a_af/h3a_aewb/hist]_config.config_counter:
+
+As the configuration doesn't take effect synchronously to the request, the
+driver must provide a way to track this information to provide more accurate
+data. After a configuration is requested, the config_counter returned to user
+space application will be an unique value associated to that request. When
+user application receives an event for buffer availability or when a new
+buffer is requested, this config_counter is used to match a buffer data and a
+configuration.
+
+VIDIOC_OMAP3ISP_STAT_REQ
+------------------------
+
+Send to user space the oldest data available in the internal buffer queue and
+discards such buffer afterwards. The field omap3isp_stat_data.frame_number
+matches with the video buffer's field_count.

+device node:

- This option prevents any floating-point instructions from being

- bool "Use write-through caching for 68060 supervisor accesses"

- The 68060 generally uses copyback caching of recently accessed data.
- Copyback caching means that memory writes will be held in an on-chip
- cache and only written back to memory some time later. Saying Y
- here will force supervisor (kernel) accesses to use writethrough
- caching. Writethrough caching means that data is written to memory
- straight away, so that cache and memory data always agree.
- Writethrough caching is less efficient, but is needed for some
- drivers on 68060 based systems where the 68060 bus snooping signal
- is hardwired on. The 53c710 SCSI driver is known to suffer from

- * Linux/m68k support by Hamish Macdonald

- * 1997-12-01 Modified for POSIX.1b signals by Andreas Schwab
- *
- * mathemu support by Roman Zippel
- * (Note: fpstate in the signal context is completely ignored for the emulator

- * ++roman (07/09/96): implemented signal stacks (specially for tosemu on
- * Atari :-) Current limitation: Only one sigstack can be active at one time.
- * If a second signal with SA_ONSTACK set arrives while working on a sigstack,
- * SA_ONSTACK is ignored. This behaviour avoids lots of trouble with nested
- * signal handlers!

+ *
+ * 03/02/96 Jes Sorensen, Andreas Schwab, Roman Hodek:
+ * Fixed some nasty bugs, causing some horrible crashes.
+ * A: At some points, the sum (%0) was used as
+ * length-counter instead of the length counter
+ * (%1). Thanks to Roman Hodek for pointing this out.
+ * B: GCC seems to mess up if one uses too many
+ * data-registers to hold input values and one tries to
+ * specify d0 and d1 as scratch registers. Letting gcc
+ * choose these registers itself solves the problem.

* Functions to sequence FLUSH and FUA writes.

+ * Copyright (C) 2011 Max Planck Institute for Gravitational Physics
+ * Copyright (C) 2011 Tejun Heo <tj@kernel.org>
+ *
+ * This file is released under the GPLv2.
+ *
+ * REQ_{FLUSH|FUA} requests are decomposed to sequences consisted of three
+ * optional steps - PREFLUSH, DATA and POSTFLUSH - according to the request
+ * properties and hardware capability.
+ *
+ * If a request doesn't have data, only REQ_FLUSH makes sense, which
+ * indicates a simple flush request. If there is data, REQ_FLUSH indicates
+ * that the device cache should be flushed before the data is executed, and
+ * REQ_FUA means that the data must be on non-volatile media on request
+ * completion.
+ *
+ * If the device doesn't have writeback cache, FLUSH and FUA don't make any
+ * difference. The requests are either completed immediately if there's no
+ * data or executed as normal requests otherwise.
+ *
+ * If the device has writeback cache and supports FUA, REQ_FLUSH is
+ * translated to PREFLUSH but REQ_FUA is passed down directly with DATA.
+ *
+ * If the device has writeback cache and doesn't support FUA, REQ_FLUSH is
+ * translated to PREFLUSH and REQ_FUA to POSTFLUSH.
+ *
+ * The actual execution of flush is double buffered. Whenever a request
+ * needs to execute PRE or POSTFLUSH, it queues at
+ * q->flush_queue[q->flush_pending_idx]. Once certain criteria are met, a
+ * flush is issued and the pending_idx is toggled. When the flush
+ * completes, all the requests which were pending are proceeded to the next
+ * step. This allows arbitrary merging of different types of FLUSH/FUA
+ * requests.
+ *
+ * Currently, the following conditions are used to determine when to issue
+ * flush.
+ *
+ * C1. At any given time, only one flush shall be in progress. This makes
+ * double buffering sufficient.
+ *
+ * C2. Flush is deferred if any request is executing DATA of its sequence.
+ * This avoids issuing separate POSTFLUSHes for requests which shared
+ * PREFLUSH.
+ *
+ * C3. The second condition is ignored if there is a request which has
+ * waited longer than FLUSH_PENDING_TIMEOUT. This is to avoid
+ * starvation in the unlikely case where there are continuous stream of
+ * FUA (without FLUSH) requests.
+ *
+ * For devices which support FUA, it isn't clear whether C2 (and thus C3)
+ * is beneficial.
+ *
+ * Note that a sequenced FLUSH/FUA request with DATA is completed twice.
+ * Once while executing DATA and again after the whole sequence is
+ * complete. The first completion updates the contained bio but doesn't
+ * finish it so that the bio submitter is notified only after the whole
+ * sequence is complete. This is implemented by testing REQ_FLUSH_SEQ in
+ * req_bio_endio().
+ *
+ * The above peculiarity requires that each FLUSH/FUA request has only one
+ * bio attached to it, which is guaranteed as they aren't allowed to be
+ * merged in the usual way.

The Intel SCH contains a total of 14 GPIO pins. Ten GPIOs are
powered by the core power rail and are turned off during sleep
modes (S3 and higher). The remaining four GPIOs are powered by
the Intel SCH suspend power supply. These GPIOs remain
active during S3. The suspend powered GPIOs can be used to wake the
system from the Suspend-to-RAM state.

+ * @ratio : return calculated ratios
+ * return none
+ *
+ * The resizer uses a polyphase sample rate converter. The upsampling filter
+ * has a fixed number of phases that depend on the resizing ratio. As the ratio
+ * computation depends on the number of phases, we need to compute a first
+ * approximation and then refine it.
+ *
+ * The input/output/ratio relationship is given by the OMAP34xx TRM:
+ *
+ * - 8-phase, 4-tap mode (RSZ = 64 ~ 512)
+ * iw = (32 * sph + (ow - 1) * hrsz + 16) >> 8 + 7
+ * ih = (32 * spv + (oh - 1) * vrsz + 16) >> 8 + 4
+ * - 4-phase, 7-tap mode (RSZ = 513 ~ 1024)
+ * iw = (64 * sph + (ow - 1) * hrsz + 32) >> 8 + 7
+ * ih = (64 * spv + (oh - 1) * vrsz + 32) >> 8 + 7
+ *
+ * iw and ih are the input width and height after cropping. Those equations need
+ * to be satisfied exactly for the resizer to work correctly.
+ *
+ * Reverting the equations, we can compute the resizing ratios with
+ *
+ * - 8-phase, 4-tap mode
+ * hrsz = ((iw - 7) * 256 - 16 - 32 * sph) / (ow - 1)
+ * vrsz = ((ih - 4) * 256 - 16 - 32 * spv) / (oh - 1)
+ * - 4-phase, 7-tap mode
+ * hrsz = ((iw - 7) * 256 - 32 - 64 * sph) / (ow - 1)
+ * vrsz = ((ih - 7) * 256 - 32 - 64 * spv) / (oh - 1)
+ *
+ * The ratios are integer values, and must be rounded down to ensure that the
+ * cropped input size is not bigger than the uncropped input size. As the ratio
+ * in 7-tap mode is always smaller than the ratio in 4-tap mode, we can use the
+ * 7-tap mode equations to compute a ratio approximation.
+ *
+ * We first clamp the output size according to the hardware capabilitie to avoid
+ * auto-cropping the input more than required to satisfy the TRM equations. The
+ * minimum output size is achieved with a scaling factor of 1024. It is thus
+ * computed using the 7-tap equations.
+ *
+ * min ow = ((iw - 7) * 256 - 32 - 64 * sph) / 1024 + 1
+ * min oh = ((ih - 7) * 256 - 32 - 64 * spv) / 1024 + 1
+ *
+ * Similarly, the maximum output size is achieved with a scaling factor of 64
+ * and computed using the 4-tap equations.
+ *
+ * max ow = ((iw - 7) * 256 + 255 - 16 - 32 * sph) / 64 + 1
+ * max oh = ((ih - 4) * 256 + 255 - 16 - 32 * spv) / 64 + 1
+ *
+ * The additional +255 term compensates for the round down operation performed
+ * by the TRM equations when shifting the value right by 8 bits.
+ *
+ * We then compute and clamp the ratios (x1/4 ~ x4). Clamping the output size to
+ * the maximum value guarantees that the ratio value will never be smaller than
+ * the minimum, but it could still slightly exceed the maximum. Clamping the
+ * ratio will thus result in a resizing factor slightly larger than the
+ * requested value.
+ *
+ * To accomodate that, and make sure the TRM equations are satisfied exactly, we
+ * compute the input crop rectangle as the last step.
+ *
+ * As if the situation wasn't complex enough, the maximum output width depends
+ * on the vertical resizing ratio. Fortunately, the output height doesn't
+ * depend on the horizontal resizing ratio. We can then start by computing the
+ * output height and the vertical ratio, and then move to computing the output
+ * width and the horizontal ratio.

+ * Stream management
+ *
+ * Every ISP pipeline has a single input and a single output. The input can be
+ * either a sensor or a video node. The output is always a video node.
+ *
+ * As every pipeline has an output video node, the ISP video objects at the
+ * pipeline output stores the pipeline state. It tracks the streaming state of
+ * both the input and output, as well as the availability of buffers.
+ *
+ * In sensor-to-memory mode, frames are always available at the pipeline input.
+ * Starting the sensor usually requires I2C transfers and must be done in
+ * interruptible context. The pipeline is started and stopped synchronously
+ * to the stream on/off commands. All modules in the pipeline will get their
+ * subdev set stream handler called. The module at the end of the pipeline must
+ * delay starting the hardware until buffers are available at its output.
+ *
+ * In memory-to-memory mode, starting/stopping the stream requires
+ * synchronization between the input and output. ISP modules can't be stopped
+ * in the middle of a frame, and at least some of the modules seem to become
+ * busy as soon as they're started, even if they don't receive a frame start
+ * event. For that reason frames need to be processed in single-shot mode. The
+ * driver needs to wait until a frame is completely processed and written to
+ * memory before restarting the pipeline for the next frame. Pipelined
+ * processing might be possible but requires more testing.
+ *
+ * Stream start must be delayed until buffers are available at both the input
+ * and output. The pipeline must be started in the videobuf queue callback with
+ * the buffers queue spinlock held. The modules subdev set stream operation must
+ * not sleep.

-1. Both ir-kbd-i2c and lirc_zilog provide support for RX events.
-The 'tx_only' lirc_zilog module parameter will allow ir-kbd-i2c
-and lirc_zilog to coexist in the kernel, if the user requires such a set-up.
-However the IR unit will not work well without coordination between the
-two modules. A shared mutex, for transceiver access locking, needs to be
-supplied by bridge drivers, in struct IR_i2_init_data, to both ir-kbd-i2c
-and lirc_zilog, before they will coexist usefully. This should be fixed
-before moving out of staging.
+1. Both ir-kbd-i2c and lirc_zilog provide support for RX events for
+the chips supported by lirc_zilog. Before moving lirc_zilog out of staging:
-2. References and locking need careful examination. For cx18 and ivtv PCI
-cards, which are not easily "hot unplugged", the imperfect state of reference
-counting and locking is acceptable if not correct. For USB connected units
-like HD PVR, PVR USB2, HVR-1900, and HVR1950, the likelyhood of an Ooops on
-unplug is probably great. Proper reference counting and locking needs to be
-implemented before this module is moved out of staging.
+a. ir-kbd-i2c needs a module parameter added to allow the user to tell
+ ir-kbd-i2c to ignore Z8 IR units.
-3. The binding between hdpvr and lirc_zilog is currently disabled,
-due to an OOPS reported a few years ago when both the hdpvr and cx18
-drivers were loaded in his system. More details can be seen at:
- http://www.mail-archive.com/linux-media@vger.kernel.org/msg09163.html
-More tests need to be done, in order to fix the reported issue.
+b. lirc_zilog should provide Rx key presses to the rc core like ir-kbd-i2c
+ does.
-4. In addition to providing a shared mutex for transceiver access
-locking, bridge drivers, if able, should provide a chip reset() callback
+
+2. lirc_zilog module ref-counting need examination. It has not been
+verified that cdev and lirc_dev will take the proper module references on
+lirc_zilog to prevent removal of lirc_zilog when the /dev/lircN device node
+is open.
+
+(The good news is ref-counting of lirc_zilog internal structures appears to be
+complete. Testing has shown the cx18 module can be unloaded out from under
+irw + lircd + lirc_dev, with the /dev/lirc0 device node open, with no adverse
+effects. The cx18 module could then be reloaded and irw properly began
+receiving button presses again and ir_send worked without error.)
+
+
+3. Bridge drivers, if able, should provide a chip reset() callback
to lirc_zilog via struct IR_i2c_init_data. cx18 and ivtv already have routines
-to perform Z8 chip resets via GPIO manipulations. This will allow lirc_zilog
+to perform Z8 chip resets via GPIO manipulations. This would allow lirc_zilog
to bring the chip back to normal when it hangs, in the same places the
original lirc_pvr150 driver code does. This is not strictly needed, so it
is not required to move lirc_zilog out of staging.

+Note: Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed

must consider at least the following bridge drivers which mention an IR Rx unit
at address 0x71 (indicative of a Z8):

- * The ITE8709 device seems to be the combination of IT8512 superIO chip and
- * a specific firmware running on the IT8512's embedded micro-controller.
- * In addition of the embedded micro-controller, the IT8512 chip contains a
- * CIR module and several other modules. A few modules are directly accessible
- * by the host CPU, but most of them are only accessible by the
- * micro-controller. The CIR module is only accessible by the micro-controller.
- * The battery-backed SRAM module is accessible by the host CPU and the
- * micro-controller. So one of the MC's firmware role is to act as a bridge

Saying Y here includes support for SquashFS 4.0 (a Compressed
Read-Only File System). Squashfs is a highly compressed read-only
- filesystem for Linux. It uses zlib/lzo compression to compress both
- files, inodes and directories. Inodes in the system are very small
- and all blocks are packed to minimise data overhead. Block sizes
- greater than 4K are supported up to a maximum of 1 Mbytes (default
- block size 128K). SquashFS 4.0 supports 64 bit filesystems and files
- (larger than 4GB), full uid/gid information, hard links and
