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

2020-04-14T08:31:49Z

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: docs: split ci.rst into uAPI and user guide docs

2020-04-14T08:29:06Z

The ci.rst file contains two parts: the first one describing how to use the CA high level interface; the second one with uAPI internals. Split this on two separate files, adding the uAPI bits to the DVB ca.rst configuration. Signed-off-by: Mauro Carvalho Chehab

media: v4l: Add 1X14 14-bit greyscale media bus code definition

2020-03-20T08:01:16Z

The code is called MEDIA_BUS_FMT_Y14_1X14 and behaves just like MEDIA_BUS_FMT_Y12_1X12 with two more bits. Signed-off-by: Daniel Glöckner Signed-off-by: Hans Verkuil Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: v4l: Add 14-bit raw greyscale pixel format

2020-03-20T08:00:56Z

The new format is called V4L2_PIX_FMT_Y14. Like V4L2_PIX_FMT_Y10 and V4L2_PIX_FMT_Y12 it is stored in two bytes per pixel but has only two unused bits at the top. Signed-off-by: Daniel Glöckner Signed-off-by: Hans Verkuil Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: v4l: Add 14-bit raw bayer pixel formats

2020-03-20T08:00:23Z

The formats added by this patch are: V4L2_PIX_FMT_SBGGR14 V4L2_PIX_FMT_SGBRG14 V4L2_PIX_FMT_SGRBG14 V4L2_PIX_FMT_SRGGB14 Signed-off-by: Jouni Ukkonen Signed-off-by: Sakari Ailus [dg@emlix.com: rebased onto current media_tree] Signed-off-by: Daniel Glöckner Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: uapi: h264: Add DPB entry field reference flags

2020-03-02T10:19:13Z

Using the field information attached to v4l2 buffers is not enough to determine the type of field referenced by a DPB entry: the decoded frame might contain the full picture (both top and bottom fields) but the reference only point to one of them. Let's add new V4L2_H264_DPB_ENTRY_FLAG_ flags to express that. [Keep only 2 flags and add some details about they mean] Signed-off-by: Jonas Karlman Signed-off-by: Boris Brezillon Signed-off-by: Ezequiel Garcia Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: Documentation/media/uapi: more readable unions

2020-02-24T16:52:44Z

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: vidioc-queryctrl.rst: fix error code

2020-02-24T15:14:06Z

An attempt to get a BUTTON control returns EACCES, not EINVAL. BUTTON controls have V4L2_CTRL_FLAG_WRITE_ONLY set, and the documentation for that flag correctly says that getting a write-only control returns EACCES. It's the description of the BUTTON type that's wrong, so fix that so they are consistent. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
