7a4b3770d6 media: v4l: Add definition for the Aspeed JPEG format
This introduces support for the Aspeed JPEG format, where the new frame
can refer to previous frame to reduce the amount of compressed data.
The concept is similar to I/P frame of video compression. It will
compare the new frame with previous one to decide which macroblock's
data is changed, and only the changed macroblocks will be compressed.

This Aspeed JPEG format is used by the video engine on Aspeed platforms,
which is generally adapted for remote KVM.

Added p_s32 and p_s64 pointers to the union in struct v4l2_ext_control to
simplify INTEGER and INTEGER64 control array support.

Internally the control framework handles such arrays just fine, but
userspace is missing corresponding pointers to access array elements of
these types.

The internal union v4l2_ctrl_ptr which the control framework uses already
has these types, they just were never added to the public API.

The V4L2_CAP_ASYNCIO capability was never implemented (and in fact
it isn't clear what it was supposed to do in the first place).

Drop it from the capabilities list. Keep it in videodev2.h with the

This will free up a capability bit for other future uses. And having
an unused and undefined I/O method is just plain confusing.

64fe675e99 media: videodev2.h: add V4L2_CTRL_FLAG_DYNAMIC_ARRAY
Add a new flag that indicates that this control is a dynamically sized
array. Also document this flag.

Currently dynamically sized arrays are limited to one dimensional arrays,
but that might change in the future if there is a need for it.

The initial use-case of dynamic arrays are stateless codecs. A frame
can be divided in many slices, so you want to provide an array containing
slice information for each slice. Typically the number of slices is small,
but the standard allow for hundreds or thousands of slices. Dynamic arrays
are a good solution since sizing the array for the worst case would waste
substantial amounts of memory.

Unlike the recently introduced tiled formats (V4L2_PIX_FMT_NV12_4L4, etc)
these formats have remained Samsung-specific until now. Therefore, and

f4815b3991 media: uapi: move MPEG-2 stateless controls out of staging
Until now, the MPEG-2 V4L2 API was not exported as a public API,
and only defined in a private media header (media/mpeg2-ctrls.h).

After reviewing the MPEG-2 specification in detail, and reworking
the controls so they match the MPEG-2 semantics properly,
we can consider it ready.

363240ce1c media: uapi: move VP8 stateless controls out of staging
Until now, the VP8 V4L2 API was not exported as a public API,
and only defined in a private media header (media/vp8-ctrls.h).

The reason for this was a concern about the API not complete
and ready to support VP8 decoding hardware accelerators.

After reviewing the VP8 specification in detail, and now
that the API is able to support Cedrus and Hantro G1,
we can consider this ready.

e9a66489c3 media: doc: pixfmt-rgb: Clarify naming scheme for RGB formats
The naming scheme for the RGB pixel formats has been developed
organically, and isn't consistent between formats using less than 8 bits
per pixels (mostly stored in 1 or 2 bytes per pixel, except for RGB666
that uses 4 bytes per pixel) and formats with 8 bits per pixel (stored
in 3 or 4 bytes). For the latter category, the names use a components
order convention that is the opposite of the first category, and the
opposite of DRM pixel formats. This has led to lots of confusion in the
past, and would really benefit from being explained more precisely. Do
so, which also prepares for the addition of additional RGB pixels
formats.

206bc0f6fb media: vicodec: mark the stateless FWHT API as stable
The FWHT stateless 'uAPI' was staging and marked explicitly in the
V4L2 specification that it will change and is unstable.
Note that these control IDs were never exported as a public API,
they were only defined in kernel-local headers (fwht-ctrls.h).

Now, the FWHT stateless controls is ready to be part
of the stable uAPI.

While not too late:

- Rename V4L2_CID_MPEG_VIDEO_FWHT_PARAMS to V4L2_CID_STATELESS_FWHT_PARAMS.

- Move the contents of fwht-ctrls.h to v4l2-controls.h.

- Move the public parts of drivers/media/test-drivers/vicodec/codec-fwht.h
  to v4l2-controls.h.

- Add V4L2_CTRL_TYPE_FWHT_PARAMS control initialization and validation.

- Add p_fwht_params to struct v4l2_ext_control.
