Merge branch 'exynos-drm-next' of git://git.infradead.org/users/kmpark/linux-samsung into drm-next

Inki writes:
"this patch set updates exynos drm framework and includes minor fixups.
and this pull request except hdmi device tree support patch set posted
by Rahul Sharma because that includes media side patch so for this
patch set, we may have git pull one more time in addition, if we get
an agreement with media guys. for this patch, you can refer to below link,
        http://comments.gmane.org/gmane.comp.video.dri.devel/74504

 this pull request adds hdmi device tree support
and includes related patch set such as disabling of hdmi internal
interrupt, suppport for platform variants for hdmi and mixer,
support to disable video processor based on platform type and
removal of drm common platform data. as you know, this patch
set was delayed because it included an media side patch. so for this,
we got an ack from v4l2-based hdmi driver author, Tomasz Stanislawski."
