Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
This is a second pull-request which adds last part of
atomic modeset/pageflip support, render node support,
clean-up, and fix-up.
* 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
drm/exynos: fix build warning to exynos_drm_gem.c
drm/exynos: Properly report supported formats for each device
drm/exynos: add render node support
drm/exynos: implement atomic_{begin/flush} of DECON
drm/exynos: remove legacy ->suspend()/resume()
drm/exynos: Enable atomic modesetting feature
drm/exynos: remove wait queue for pending page flip
drm/exynos: wait all planes updates to finish
drm/exynos: add atomic asynchronous commit
drm/exynos: fimd: only finish update if START == START_S
drm/exynos: add macro to get the address of START_S reg
drm/exynos: check for pending fb before finish update
drm/exynos: fimd: move window protect code to prepare/cleanup_plane
drm/exynos: add prepare and cleanup phases for planes
drm/exynos: fimd: unify call to exynos_drm_crtc_finish_pageflip()
drm/exynos: don't track enabled state at exynos_crtc
