      Hello,

This patch series implement support for alpha and z-order configuration in the
R-Car DU driver for the Gen3 SoCs family.

The Gen3 SoCs delegate composition to an external IP core called VSP,
supported by a V4L2 driver. The DU driver interfaces with the VSP driver using
direct function calls. Alpha and z-order configuration is implemented in the
VSP driver, the DU driver thus just needs to pass the values using the VSP
API.

This series depends on a large VSP series that has been merged in the Linux
media git tree for v4.7. Dave, instead of merging the media tree in your tree
to pull the dependency in, it would be easier to get those two patches
upstream through the media tree. I don't expect any conflict related to the
DU driver for v4.7. If you're fine with that, could you ack the patches ?
