[RFC 03/10] v4l: Add sunxi Video Engine pixel format

From: Florent Revest
Date: Thu Aug 25 2016 - 05:40:15 EST


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.
