media: pixfmt-yuv-planar.rst: fix PIX_FMT labels

2022-03-18T06:27:37+00:00

Two labels used _ instead of - so were never found and one new PIX_FMT was
missing the label altogether. This led to these warnings:

Documentation/output/videodev2.h.rst:6: WARNING: undefined label: v4l2-pix-fmt-nv12m-8l128

media: add nv12m_8l128 and nv12m_10be_8l128 video format.

2022-03-07T16:13:31+00:00

nv12m_8l128 is 8-bit tiled nv12 format used by amphion decoder.
nv12m_10be_8l128 is 10-bit tiled format used by amphion decoder.
The tile size is 8x128

media: lirc: remove unused feature LIRC_CAN_SET_REC_DUTY_CYCLE

2022-03-07T15:29:07+00:00

There is no hardware which can filter input on the duty cycle, so no
driver implements this. On top of that, LIRC_CAN_SET_REC_DUTY_CYCLE
has the same value as LIRC_CAN_MEASURE_CARRIER (0x02000000).

Add new V4L2_H264_DECODE_PARAM_FLAG_P/BFRAME flags that are needed by
NVIDIA Tegra video decoder. Userspace will have to set these flags in
accordance to the type of a decoded frame.

doc: media: Document VP9 reference_mode miss-placement

2022-02-23T07:53:08+00:00

The reference_mode derived syntax is part of the compressed headers and
should have been moved into the corresponding control structure. Document
this mistake. The value can be set to 0 if the driver does not require
compressed headers information.

doc: media: Document MM21 tiled format

2022-02-23T07:53:08+00:00

MM21 has been documented through two software implementation [0] in libyuv
and [2] GStreamer. This format is similar to other tiled format, though it
uses uneven tile sizes. The luma tiles are 16x32 while the chroma tile have
a subsampled size of 16x16. This is the uncompressed cousin of
V4L2_PIX_FMT_MT21C and shares its tiling pattern and alignment.
