<content type='text'>
Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee3862 ("docs: Create a user-space API guide").

As the media subsystem was one of the first subsystems to use
Sphinx, until this patch, we were keeping things on a separate
place.

Let's just use the new location, as having all uAPI altogether
will likely make things easier for developers.

<content type='text'>
Avoid adding an extra columns when describing unions in the documentation.
That makes it much harder to read. See e.g. VIDIOC_QUERY_EXT_CTRLS.

Instead start off a union with 'union {' and end it with an extra row
containing '}'.

This leaves a lot more space for the description of the fields.

This formatting technique was used in a few places already, but this
patches fixes all remaining occurrences of 'union' in the media uAPI.

<title>media: docs-rst: Document memory-to-memory video decoder interface</title>

<id>urn:sha1:051f8d2d86f848cd29632908f56d277ac5800a50</id>
<content type='text'>
Due to complexity of the video decoding process, the V4L2 drivers of
stateful decoder hardware require specific sequences of V4L2 API calls
to be followed. These include capability enumeration, initialization,
decoding, seek, pause, dynamic resolution change, drain and end of
stream.

Specifics of the above have been discussed during Media Workshops at
LinuxCon Europe 2012 in Barcelona and then later Embedded Linux
Conference Europe 2014 in Düsseldorf. The de facto Codec API that
originated at those events was later implemented by the drivers we already
have merged in mainline, such as s5p-mfc or coda.

The only thing missing was the real specification included as a part of
Linux Media documentation. Fix it now and document the decoder part of
the Codec API.

The raw Bayer formats have been listed under the label of RGB formats but
in fact they're quite different. The latter are readily usable as such
whereas the former require quite bit of image processing before useful.

Split them into RGB and raw Bayer formats.

<title>media: media/doc: Allow sizeimage to be set by v4l clients</title>

<content type='text'>
This changes v4l2_pix_format and v4l2_plane_pix_format sizeimage
field description to allow v4l clients to set bigger image size
in case of variable length compressed data.

Presently s5p-mfc and mtk-vcodec codec drivers use that. Lets
make it obvious in the documentation.

This is not needed there. Also, the same UTF-8 encoding should
be used on all documents.

The v4l2_pix_format documentation still had 'enum's as types.
Replace by __u32 and add a reference to the enum.

Also put ycbcr_enc and hsv_enc in a union.
