[PATCH 3/9] v4l: Add sunxi Video Engine pixel format

From: Paul Kocialkowski
Date: Fri Mar 09 2018 - 05:17:50 EST


From: Florent Revest <florent.revest@xxxxxxxxxxxxxxxxxx>

Add support for the allwinner's proprietary pixel format described in
details here: http://linux-sunxi.org/File:Ve_tile_format_v1.pdf

This format is similar to V4L2_PIX_FMT_NV12M but the planes are divided
in tiles of 32x32px.
