The rx-arb-lost error injection command only works with  set to 'any'.
Explicitly say so in the usage message.

Also use [] to indicate that the  argument is optional.

media: v4l2-ctrl: add controls for long term reference.

2021-04-06T12:49:02+00:00

Long Term Reference (LTR) frames are the frames that are encoded
sometime in the past and stored in the DPB buffer list to be used
as reference to encode future frames.
This change adds controls to enable this feature.

media: vidioc-g-ext-ctrls.rst: reformat tables and clarify which vs ctrl_class

2021-03-22T12:04:53+00:00

The VIDIOC_G/S/TRY_EXT_CTRLS documentation has large explanatory texts for
some of the fields in a table. This makes it hard to read. Move those text
to a new cell spanning the whole width of the table, similar to what was
done for struct v4l2_pix_format. This makes it much more readable.

Also move the 'ctrl_class' description to below the 'which' description and
just mention that it is deprecated and that 'which' should be used instead.

Finally remove 'note::' for the V4L2_CTRL_WHICH_DEF_VAL description. It
doesn't have to be marked as a note, it's just a simple paragraph.

media: docs: Fix data organization of MEDIA_BUS_FMT_RGB101010_1X30

2021-03-22T10:53:28+00:00

The media bus bit width of MEDIA_BUS_FMT_RGB101010_1X30 is 30.
So, 'Bit31' and 'Bit30' cells for the 'MEDIA_BUS_FMT_RGB101010_1X30'
row should be spaces instead of '0's.
