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

 Summary:
   - expose HDMI-PHY clock to other drivers.
     . this patch was included in below patch series but I missed.
             http://www.spinics.net/lists/dri-devel/msg103097.html
   - some fixups about DECON5433 driver
     . this patch corrects vblank handling and fixes up trigger
       configuration.
   - use generic functions - gem_prime_mmap and dma_buf_mmap.
   - use DMA-Mapping API instead of specific one.
   - some code cleanups and fixeups.
