OK, I'll try to. Would you mind if we got these patches merged first for v4.7,
and then switched to a generic property for v4.8 ? The reason is that this
series depends on a large patch series queued in the linux-media tree for
v4.7, and it would be easier to handle the dependency by merging these two
patches in linux-media. A rework of the zpos and alpha properties would need
to be merged through the drm tree.
