Merge branch 'exynos-drm-next' of...

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

these patch sets include the following features:
- add Samsung SoC Exynos based HDMI support.
- add pm feature for fimd driver.
- add multi buffer plane pixel formats to drm/drm_fourcc.h.
  multi buffer plane pixel format has seperated memory spaces for each
  plane. for exampme, NV12M has Y plane and CbCr plane and these are in
  non-continuous memory region. compared with NV12, NV12M's memory shape
  is like following.
  NV12  : ______(Y)(CbCr)_______
  NV12M : __(Y)_ ..... _(CbCr)__
- bug fix to vblank.
- code clean to exynos gem framework.

* 'exynos-drm-next' of git://git.infradead.org/users/kmpark/linux-samsung:
  drm/exynos: added hdmi display support
  drm/exynos: added mutex lock and code clean.
  drm/exynos: extend vblank off delay time.
  drm/exynos: change driver name.
  drm/exynos: Support multi buffers
  drm: Add multi buffer plane pixel formats
  drm/exynos: added pm support.
  drm/exynos: remove buffer creation of fbdev from drm framebuffer creation
  drm/exynos: Split creation of gem object and gem handle
  drm/exynos: Fix a fake mmap offset creation
  drm/exynos: gem code cleanup
