2020-09-01media: docs: use the new SPDX header for GFDL-1.1 on *.rst filesMauro Carvalho Chehab1-8/+1
SPDX v3.10 gained support for GFDL-1.1 with no invariant sections: https://spdx.org/licenses/GFDL-1.1-no-invariants-or-later.html So, remove the license text, replacing them by this new SPDX license. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-08-26media: videodev2.h: RGB BT2020 and HSV are always full rangeHans Verkuil1-5/+4
The default RGB quantization range for BT.2020 is full range (just as for all the other RGB pixel encodings), not limited range. Update the V4L2_MAP_QUANTIZATION_DEFAULT macro and documentation accordingly. Also mention that HSV is always full range and cannot be limited range. When RGB BT2020 was introduced in V4L2 it was not clear whether it should be limited or full range, but full range is the right (and consistent) choice.

2020-04-14media: docs: move uAPI book to userspace-api/mediaMauro Carvalho Chehab1-0/+183
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. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
