[GIT PULL] Armada DRM (drm-armada-devel-4.15 branch)

[Russell King]

David,

Please incorporate the latest Armada DRM (drm-armada-devel-4.15 branch),
which can be found at:

  git://git.armlinux.org.uk/~rmk/linux-arm.git drm-armada-devel-4.15

with SHA1 27ab688f70b6f6b51da4bf56b1237f7beb64d847.

This series builds upon the set of fixes previously submitted to move
Armada DRM closer to atomic modeset.  We're nowhere near yet, but this
series helps to get us closer by unifying some of the differences
between the primary and overlay planes.

New features added allows userspace to disable the primary plane if
overlay is full screen and there's nothing obscuring the colorkey -
this saves having to fetch an entire buffer containing nothing but
colorkey when displaying full screen video.

This will update the following files:
