media: docs: move uAPI book to userspace-api/media

2020-04-14T08:31:49+00:00

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

media: Documentation/media/uapi: more readable unions

2020-02-24T16:52:44+00:00

Avoid adding an extra columns when describing unions in the documentation. That makes it much harder to read. See e.g. VIDIOC_QUERY_EXT_CTRLS. Instead start off a union with 'union {' and end it with an extra row containing '}'. This leaves a lot more space for the description of the fields. This formatting technique was used in a few places already, but this patches fixes all remaining occurrences of 'union' in the media uAPI.

media: media-ioc-enum-links.rst: fix incorrect reserved field documentation

2019-05-29T14:31:52+00:00

The reserved field array for struct media_link_desc has length 2, not 4. And the reserved field array of struct media_links_enum was never documented at all. Signed-off-by: Hans Verkuil Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: media requests: return EBADR instead of EACCES

2019-03-25T17:26:10+00:00

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. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: Documentation/media: rename "Codec Interface"

2019-01-25T20:54:18+00:00

The "Codec Interface" chapter is poorly named since codecs are just one use-case of the Memory-to-Memory Interface. Rename it and clean up the text a bit. Signed-off-by: Hans Verkuil Reviewed-by: Tomasz Figa Signed-off-by: Mauro Carvalho Chehab

media: docs: fix some GPL licensing ambiguity at the text

2018-12-17T15:57:20+00:00

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. Signed-off-by: Mauro Carvalho Chehab
