Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Summary:
- Add code cleanups and bug fixups.
- Add a new display controller dirver, DECON which is a new display
  controller of Exynos7 SoC. This device is much different from
  FIMD of Exynos4 and Exynos4 SoC series.

* 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
  drm/exynos: Add DECON driver
  drm/exynos: fix NULL pointer reference
  drm/exynos: remove exynos_plane_dpms
  drm/exynos: remove mode property of exynos crtc
  drm/exynos: Remove exynos_plane_dpms() call with no effect
  drm/exynos: fix DMA_ATTR_NO_KERNEL_MAPPING usage
  drm/exynos: hdmi: replace fb size with mode size from win commit
  drm/exynos: fix no hdmi output
  drm/exynos: use driver internal struct
  drm/exynos: fix wrong pipe calculation for crtc
  drm/exynos: remove to use unnecessary MODULE_xxx macro
  drm/exynos: remove DRM_EXYNOS_DMABUF config
  drm/exynos: IOMMU support should not be selectable by user
  drm/exynos: add support for 'hdmi' clock
