Add a userspace API to get, set and enumerate the media format on a
subdev pad.
The format at the output of a subdev usually depends on the format at
its input(s). The try format operation is thus not suitable for probing
format at individual pads, as it can't modify the device state and thus
can't remember the format tried at the input to compute the output
format.
To fix the problem, pass an extra argument to the get/set format
operations to select the 'try' or 'active' format.
The try format is used when probing the subdev. Setting the try format
must not change the device configuration but can store data for later
reuse. Data storage is provided at the file-handle level so applications
probing the subdev concurently won't interfere with each other.
The active format is used when configuring the subdev. It's identical to
the format handled by the usual get/set operations.

+ <para>The complex nature of V4L2 devices, where hardware is often made of

+
+ <para>V4L2 sub-devices are usually kernel-only objects. If the V4L2 driver
+ implements the media device API, they will automatically inherit from media

+ API.</para>
+

+ <title>Controls</title>
+ <para>Most V4L2 controls are implemented by sub-device hardware. Drivers
+ usually merge all controls and expose them through video device nodes.
+ Applications can control all sub-devices through a single interface.</para>
+
+ <para>Complex devices sometimes implement the same control in different
+ pieces of hardware. This situation is common in embedded platforms, where
+ both sensors and image processing hardware implement identical functions,
+ such as contrast adjustment, white balance or faulty pixels correction. As
+ the V4L2 controls API doesn't support several identical controls in a single
+ device, all but one of the identical controls are hidden.</para>
+
+ <para>Applications can access those hidden controls through the sub-device
+ node with the V4L2 control API described in <xref linkend="control" />. The
+ ioctls behave identically as when issued on V4L2 device nodes, with the
+ exception that they deal only with controls implemented in the sub-device.

+ different hardware configurations. One such exemple is shown on
+ <xref linkend="pipeline-scaling" xrefstyle="template: Figure %n" />, where

+ differently. Applications need to configure the formats at every point in
+ the pipeline explicitly.</para>
+
+ <para>Drivers that implement the <link linkend="media-controller-intro">media

+ When they do, applications can use the &VIDIOC-SUBDEV-G-FMT; and
+ &VIDIOC-SUBDEV-S-FMT; ioctls. to negotiate formats on a per-pad basis.</para>
+
+ <para>Applications are responsible for configuring coherent parameters on
+ the whole pipeline and making sure that connected pads have compatible
+ formats. The pipeline is checked for formats mismatch at &VIDIOC-STREAMON;
+ time, and an &EPIPE; is then returned if the configuration is
+ invalid.</para>
+
+ <para>Pad-level image format configuration support can be tested by calling
+ the &VIDIOC-SUBDEV-G-FMT; ioctl on pad 0. If the driver returns an &EINVAL;
+ pad-level format configuration is not supported by the sub-device.</para>
+
+ <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>Formats should be propagated from sink pads to source pads.
+ Modifying a format on a source pad should not modify the format on any
+ sink pad.</listitem>
+ <listitem>Sub-devices that scale frames using variable scaling factors
+ should reset the scale factors to default values when sink pads formats
+ are modified. If the 1:1 scaling ratio is supported, this means that
+ source pads formats should be reset to the sink pads formats.</listitem>
+ </itemizedlist>
+ </para>
+
+ <para>Formats are not propagated across links, as that would involve
+ propagating them from one sub-device file handle to another. Applications
+ must then take care to configure both ends of every link explicitly with
+ compatible formats. Identical formats on the two ends of a link are
+ guaranteed to be compatible. Drivers are free to accept different formats
+ matching device requirements as being compatible.</para>

+ <para>Those data formats transfer pixel data as (possibly downsampled) Y, U
+ and V components. The format code is made of the following information.
+ <itemizedlist>
+ <listitem>The Y, U and V components order code, as transferred on the
+ bus. Possible values are YUYV, UYVY, YVYU and VYUY.</listitem>
+ <listitem>The number of bits per pixel component. All components are
+ transferred on the same number of bits. Common values are 8, 10 and 12.
+ </listitem>
+ <listitem>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.</listitem>
+ <listitem>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.
+ </listitem>
+ </itemizedlist>
+ </para>
+
+ <para>For instance, a format where pixels are encoded as 8-bit YUV values
+ downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in the
+ U, Y, V, Y order will be named <constant>V4L2_MBUS_FMT_UYVY8_2X8</constant>.

+
+ <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

+
+ <para>These ioctls are used to negotiate the frame format at specific
+ subdev pads in the image pipeline.</para>
+
+ <para>To retrieve the current format applications set the
+ <structfield>pad</structfield> field of a &v4l2-subdev-format; to the
+ desired pad number as reported by the media API and the
+ <structfield>which</structfield> field to
+ <constant>V4L2_SUBDEV_FORMAT_ACTIVE</constant>. When they call the
+ <constant>VIDIOC_SUBDEV_G_FMT</constant> ioctl with a pointer to this
+ structure the driver fills the members of the <structfield>format</structfield>
+ field.</para>
+
+ <para>To change the current format applications set both the
+ <structfield>pad</structfield> and <structfield>which</structfield> fields
+ 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
+ structure the driver verifies the requested format, adjusts it based on the
+ hardware capabilities and configures the device. Upon return the
+ &v4l2-subdev-format; contains the current format as would be returned by a
+ <constant>VIDIOC_SUBDEV_G_FMT</constant> call.</para>
+
+ <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
+ <constant>VIDIOC_SUBDEV_G_FMT</constant> ioctl, or set the desired output
+ 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
+ close as possible to the original request.</para>
