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

2020-03-20T08:01:16+00:00

The code is called MEDIA_BUS_FMT_Y14_1X14 and behaves just like
MEDIA_BUS_FMT_Y12_1X12 with two more bits.

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

2020-03-20T08:00:56+00:00

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.

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

2020-03-02T10:19:13+00:00

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]

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: vidioc-queryctrl.rst: fix error code

2020-02-24T15:14:06+00:00

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.

media: vidioc-enum-fmt.rst: clarify format preference

2019-12-16T09:24:55+00:00

It has been decided to use the ENUM_FMT index value
as a hint for driver preference. This is defined purposedly
in a very liberal way, letting drivers define what "preference"
means.

For instance, the Hantro VPU driver indicates additional
processing to output a given format, and thus implicates
more CPU usage, which is enumerated after native (non-processed)
formats.
