+    <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:
+      <itemizedlist>
+        <listitem><para>Formats should be propagated from sink pads to source pads.

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

+      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

+      <para>The crop rectangle is retrieved and set using the

+      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

+    <title>Introduction</title>
+    <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>The media controller API aims at solving those problems.</para>

+    <title>Media device model</title>
+    <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>
+    <para>Link configuration has no side effect on other links. If an enabled

+        <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>

+        <title>Description</title>
+        <para>This is the two-plane versions of the YUV 4:2:0 format where data
+is grouped into 64x32 macroblocks. The three components are separated into two
+sub-images or planes. The Y plane has one byte per pixel and pixels are grouped
+into 64x32 macroblocks. The CbCr plane has the same width, in bytes, as the Y
+plane (and the image), but is half as tall in pixels. The chroma plane is also
+grouped into 64x32 macroblocks.</para>
+        <para>Width of the buffer has to be aligned to the multiple of 128, and
+height alignment is 32. Every four adjactent buffers - two horizontally and two
+vertically are grouped together and are located in memory in Z or flipped Z
+order. </para>
+        <para>Layout of macroblocks in memory is presented in the following
+figure.</para>

+        The requirement that width is multiple of 128 is implemented because,

+of macroblocks is odd then the last row of macroblocks is arranged in a linear
+order.  </para>
+        <para>In case of chroma the layout is identical. Cb and Cr samples are

+        <para>The following four pixel formats are raw sRGB / Bayer formats with
+12 bits per colour. Each colour component is stored in a 16-bit word, with 6
+unused high bits filled with zeros. Each n-pixel row contains n/2 green samples
+and n/2 blue or red samples, with alternating red and blue rows. Bytes are
+stored in memory in little endian order. They are conventionally described
+as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of these

+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

+    image sensors and TV tuners.</para>
+    <para>For the common use case of image sensors, the frame intervals

+    <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>

+    <para>To change the current format applications set both the

+    and all members of the <structfield>format</structfield> field. When they
+    call the <constant>VIDIOC_SUBDEV_S_FMT</constant> ioctl with a pointer to this

+    hardware capabilities and configures the device. Upon return the
+    &v4l2-subdev-format; contains the current format as would be returned by a

+    <para>Applications can query the device capabilities by setting the
+    <structfield>which</structfield> to
+    <constant>V4L2_SUBDEV_FORMAT_TRY</constant>. When set, 'try' formats are not
+    applied to the device by the driver, but are changed exactly as active
+    formats and stored in the sub-device file handle. Two applications querying
+    the same sub-device would thus not interact with each other.</para>
+    <para>For instance, to try a format at the output pad of a sub-device,
+    applications would first set the try format at the sub-device input with the
+    <constant>VIDIOC_SUBDEV_S_FMT</constant> ioctl. They would then either
+    retrieve the default format at the output pad with the

+    pad format with the <constant>VIDIOC_SUBDEV_S_FMT</constant> ioctl and check
+    the returned value.</para>
+    <para>Try formats do not depend on active formats, but can depend on the
+    current links configuration or sub-device controls value. For instance, a
+    low-pass noise filter might crop pixels at the frame boundaries, modifying
+    its output frame size.</para>
+    <para>Drivers must not return an error solely because the requested format
+    doesn't match the device capabilities. They must instead modify the format
+    to match what the hardware can provide. The modified format should be as

-If group_isolation=1, it provides stronger isolation between groups at the

-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.

+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

+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.

+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.

+V4L2 sub-device userspace API
+-----------------------------
+Beside exposing a kernel API through the v4l2_subdev_ops structure, V4L2
+sub-devices can also be controlled directly by userspace applications.
+Device nodes named v4l-subdevX can be created in /dev to access sub-devices
+directly. If a sub-device supports direct userspace configuration it must set
+the V4L2_SUBDEV_FL_HAS_DEVNODE flag before being registered.
+After registering sub-devices, the v4l2_device driver can create device nodes
+for all registered sub-devices marked with V4L2_SUBDEV_FL_HAS_DEVNODE by calling
+v4l2_device_register_subdev_nodes(). Those device nodes will be automatically
+removed when sub-devices are unregistered.

+device node:
+int v4l2_fh_is_singular(struct v4l2_fh *fh)

+ *
+ * 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

          This driver can also be built as a module. If so, the module
          will be called sch-gpio.

+ * @num_pads: Total number of sink and source pads.
+ * @extra_links: Initial estimate of the number of extra links.
+ * @pads: Array of 'num_pads' pads.
+ *
+ * The total number of pads is an intrinsic property of entities known by the
+ * entity driver, while the total number of links depends on hardware design
+ * and is an extrinsic property unknown to the entity driver. However, in most
+ * use cases the entity driver can guess the number of links which can safely
+ * be assumed to be equal to or larger than the number of pads.
+ *
+ * For those reasons the links array can be preallocated based on the entity
+ * driver guess and will be reallocated later if extra links need to be
+ * created.
+ *
+ * This function allocates a links array with enough space to hold at least
+ * 'num_pads' + 'extra_links' elements. The media_entity::max_links field will
+ * be set to the number of allocated elements.
+ *
+ * The pads array is managed by the entity driver and passed to
+ * media_entity_init() where its pointer will be stored in the entity structure.

+ *  FM Driver for Connectivity chip of Texas Instruments.
+ *
+ *  This sub-module of FM driver is common for FM RX and TX
+ *  functionality. This module is responsible for:
+ *  1) Forming group of Channel-8 commands to perform particular
+ *     functionality (eg., frequency set require more than
+ *     one Channel-8 command to be sent to the chip).
+ *  2) Sending each Channel-8 command to the chip and reading
+ *     response back over Shared Transport.
+ *  3) Managing TX and RX Queues and Tasklets.
+ *  4) Handling FM Interrupt packet and taking appropriate action.
+ *  5) Loading FM firmware to the chip (common, FM TX, and FM RX
+ *     firmware files based on mode selection)

+   to a much more stable image then using the knee algorithm which at
+   certain points of the knee graph will only try to adjust exposure,
+   which leads to oscilating as one exposure step is huge.
+   Note this assumes that the sd struct for the cam in question has

+ *
+ * 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.

-          brought to you by the DAB-Team
-          <http://wwwbode.cs.tum.edu/Par/arch/dab/>.  This driver can be taken
-          as an example for URB-based bulk, control, and isochronous
-          transactions. URB's are explained in
-          <Documentation/usb/URB.txt>.
-          To compile this driver as a module, choose M here: the
-          module will be called dabusb.

-/*
- * 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
- * between the host CPU and the CIR module. The firmware implements a kind of
- * communication protocol using the SRAM module as a shared memory. The IT8512
- * specification is publicly available on ITE's web site, but the communication
- * protocol is not, so it was reverse-engineered.

+ * reserved, V4L2_MBUS_FMT_FIXED shall be used by host-client pairs, where the
+ * data format is fixed. Additionally, "2X8" means that one pixel is transferred
+ * in two 8-bit samples, "BE" or "LE" specify in which order those samples are
+ * transferred over the bus: "LE" means that the least significant bits are
+ * transferred first, "BE" means that the most significant bits are transferred
+ * first, and "PADHI" and "PADLO" define which bits - low or high, in the
+ * incomplete high byte, are filled with padding bits.
+ *
+ * The pixel codes are grouped by type, bus_width, bits per component, samples
+ * per pixel and order of subsamples. Numerical values are sorted using generic
+ * numerical sort order (8 thus comes before 10).
+ *
+ * As their value can't change when a new pixel code is inserted in the
