Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
This 2nd pull request includes the following,
- add configurable plane support and relevant cleanups.
- fixup kernel panic issue at drm releasing.
- remove unnecessary codes.
This has been delayed to resolve a critical issue - which incurrs
a kernel panic when driver is released - and review it.
* 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
drm/exynos: fix kernel panic issue at drm releasing
drm/exynos: crtc: do not wait for the scanout completion
drm/exynos: mixer: properly update all planes on the same vblank event
drm/exynos: crtc: rework atomic_{begin,flush}
drm/exynos: mixer: unify a check for video-processor window
drm/exynos: mixer: also allow ARGB1555 and ARGB4444
drm/exynos: mixer: refactor layer setup
drm/exynos: mixer: remove all static blending setup
drm/exynos: mixer: set window priority based on zpos
drm/exynos: make zpos property configurable
drm/exynos: rename zpos to index
