I think it can be added as V4L2_PIX_FMT_NV12MT_32X32. This needs to be documented in the V4L2 spec as well, of course.

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.
