[PATCH v6 1/4] media: v4l: Add 1X16 16-bit greyscale media bus code definition

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This extends the greyscale media bus family originally from
MEDIA_BUS_FMT_Y8_1X8 up to MEDIA_BUS_FMT_Y14_1X14 by adding
MEDIA_BUS_FMT_Y16_1X16, and behaves the same way with 16 bits.
Add its documentation in subdev-formats.rst
