2020-12-07media: doc: pixfmt-yuv: Move all semi-planar YUV formats to common fileLaurent Pinchart
Semi-planar pixel formats are documented in separate files. This duplicates information, as those formats share comon traits. Consolidate them in a single file and summarize their descriptions in a single table.

2020-09-01media: docs: use the new SPDX header for GFDL-1.1 on *.rst filesMauro Carvalho Chehab
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>
2020-04-14media: docs: move uAPI book to userspace-api/mediaMauro Carvalho Chehab
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>
