Great, thanks for pointing me to this co
This control is to be used with the new low-level decoder API for
MPEG2 to provide additional parameters for the hardware that cannot parse
the input stream.

ngineering on which I based my work comes from the
"Cedrus" project: http://linux-sunxi.org/Cedrus
The driver currently only runs on the A13 and this patch doesn't
include any codec.

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.

Add a new style driver for the clock control unit in Allwinner A13.
Only AVS and VE are supported since they weren't provided until now and are
needed for "sunxi-cedrus".

Now that we have a driver matching "allwinner,sun5i-a13-video-engine" we
can load it.
The "video-engine" node depends on the new sunxi-ng's CCU clock and
reset bindings. This patch also includes a ve_reserved DMA pool for
videobuf2 buffer allocations in sunxi-cedrus.
