6e1d824e7a media: Media Device Allocator API
Media Device Allocator API to allows multiple drivers share a media device.
This API solves a very common use-case for media devices where one physical
device (an USB stick) provides both audio and video. When such media device
exposes a standard USB Audio class, a proprietary Video class, two or more
independent drivers will share a single physical USB bridge. In such cases,
it is necessary to coordinate access to the shared resource.

Using this API, drivers can allocate a media device with the shared struct
device as the key. Once the media device is allocated by a driver, other
drivers can get a reference to it. The media device is released when all
the references are released.

e79c7159d4 media: media requests: return EBADR instead of EACCES
If requests are used when they shouldn't, or not used when they should,
then return EBADR (Invalid request descriptor) instead of EACCES.

The reason for this change is that EACCES has more to do with permissions
(not being the owner of the resource), but in this case the request file
descriptor is just wrong for the current mode of the device.

Update the documentation accordingly.

90675d391e media: vb2: add requires_requests bit for stateless codecs
Stateless codecs require the use of the Request API as opposed of it
being optional.

So add a bit to indicate this and let vb2 check for this.

If an attempt is made to queue a buffer without an associated request,
then the EBADR error is returned to userspace.

Doing this check in the vb2 core simplifies drivers, since they
don't have to check for this, they can just set this flag.

4f14e3272f extended-controls.rst: split up per control class
The extended-controls.rst file had become too big. Split it up: each
control class reference gets its own rst file, and this file just
describes the Extended Control API.

Each control class reference is also moved up one level into the
table of contents to make it easier to find e.g. the codec control
reference.

Finally I rearranged the order so that all camera-related control
classes are grouped together, ditto for codec/jpeg and fm-rx/tx.

The ext-ctrls-codec.rst is still pretty big and it is a candidate
to split up further in the future, possibly per codec.

e7121ab405 media: docs: fix some GPL licensing ambiguity at the text
Those files are meant to be dual GPL 2.0 and GFDL without
implicit sections. However, by a wrong cut-and-paste, I ended
by applying a GPL 2+ license text to it, while still using the
GPL 2.0 SPDX tag, with would cause an ambiguity about the
licensing model.

Solve this by explicitly mentioning that the dual licensing
is between GPL 2.0 and GFDL and correcting the text.

The venus and s5p-mfc drivers add the loop filter alpha/beta offset
controls V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_ALPHA/BETA with a range of
-6 to +6, inclusive. This is exactly the range specified for the slice
header fields slice_alpha_c0_offset_div2 and slice_beta_offset_div2,
which store half the actual filter offsets FilterOffsetA/B.

Clarify that this control contains the halved offsets.
