2023-12-13media: docs: uAPI: Expand error documentation for invalid 'which' valueLaurent Pinchart
Multiple subdev ioctls that take a 'which' field do not document the error returned when the field has an invalid value. Expand the documentation to fix this. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
2023-01-22media: subdev: add stream based configurationTomi Valkeinen
Add support to manage configurations (format, crop, compose) per stream, instead of per pad. This is accomplished with data structures that hold an array of all subdev's stream configurations. The number of streams can vary at runtime based on routing. Every time the routing is changed, the stream configurations need to be re-initialized.

2021-03-11media: docs: uAPI: fix table output in LaTeX/PDF formatMauro Carvalho Chehab
There are lots of tables that are not properly displayed in LaTeX/PDF. Fix the tablecolumns, add longtable where needed and LaTeX formatting macros, in order to address such issues. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-10-15media: docs: make V4L documents more compatible with Sphinx 3.1+Mauro Carvalho Chehab
Sphinx 3.x broke support for the cdomain.py extension, as the c domain code was rewritten. Due to that, the c tags need to be re-written, in order to use the new c domain notation. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
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>
