Subject[PATCH v8 1/9] media: v4l: Add packed YUV444 24bpp pixel format
Date
From: Mirela Rabulea <mirela.rabulea@nxp.com>

The added format is V4L2_PIX_FMT_YUV24, this is a packed
YUV 4:4:4 format, with 8 bits for each component, 24 bits
per sample.

This format is used by the i.MX 8QuadMax and i.MX 8DualXPlus/8QuadXPlus
JPEG encoder/decoder.
