Hello Dave,
This pull request is for z-pos feature. It include generic code for new z-pos property and functions to normalize it (in a new file named drm_blend.c) Three drivers (exynos, rcard-du and sti) have been modified to take benefit of this generic implementation of z-order.
I have to warn you that thoses commits are rebased on top of drm-next branch where git://linuxtv.org/media_tree.git vsp1 branch has been merged.
The following changes since commit 62c2cd0f49333a2bb53602ec23039ca99a19cb9d:
