2023-04-23media: Adjust column width for pdfdocsAkira Yokosawa
The column width specifiers added in commit 8d0e3fc61abd ("media: Add 2-10-10-10 RGB formats") don't suffice for column 1 and too wide for column 2. Adjust them to get a good looking table.

2023-04-23media: Fix building pdfdocsTomi Valkeinen
Commit 8d0e3fc61abd ("media: Add 2-10-10-10 RGB formats") added documentation for a few new RGB formats. The table has column-width specifiers for 34 columns used in pdfdocs build. However, the new table has a couple of rows with 35 columns which confused Sphinx's latex builder. The resulting .tex file causes an error in a later stage of a pdfdocs build. Remove the trailing empty dash lines to fix the issue.

2020-12-07media: doc: pixfmt-rgb: Make 8 bits per component table more compactLaurent Pinchart
All formats using 8 bits per component can be described with a byte granularity instead of a bit granularity without loss of precision. This makes the corresponding table more compact and easier to read.

2020-12-07media: doc: pixfmt-rgb: Clarify naming scheme for RGB formatsLaurent Pinchart
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.

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>
