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

Inki wrote:

this patch set includes the following:
- update of crtc and plane module.
  . the interface of crtc and plane to control overlay is integrated
    internally. for this some code fixings are added. also this supports
    the exynos specific property or crtc and plane.
- change exynos gem allocation interface.
  . this patch makes non-contiguous memory allocation request allocate pages
    from highmem through alloc_page() with GFP_HIGHUSER_MOVABLE because
    cpu may read garbage data from cache once gpu operation is completed with
    allocated pages.
    shmem_read_mapping_page_gfp() first tries to allocate pages from page
    cache so if pages are alloated from page cache then these pages could
    have valid line and we had faced with this issue.
- add exception codes to vidi module.
  . edid data from user should be allocatd and copied into vidi context and
    also freed with disconnection.
- and code clean.
