Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/…
Browse files Browse the repository at this point in the history 
…kernel/git/daeinki/drm-exynos into drm-next

  This pull request includes some code refactoring which removes
   Exynos specific structure names and uses generic structure
   names instead, and makes all plane updating to be done
   by only exynos_update_plane function. And also it includes
   some cleanup and fixup patches.

* 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: (22 commits)
  drm/exynos: fimd: check error status for drm_iommu_attach_device
  drm/exynos: create exynos_check_plane()
  drm/exynos: remove mode_set() ops from exynos_crtc
  drm/exynos: don't duplicate drm_display_mode in fimd context
  drm/exynos: remove struct exynos_drm_manager
  drm/exynos: remove drm_dev from struct exynos_drm_manager
  drm/exynos: move 'type' from manager to crtc struct
  drm/exynos: remove pipe member of struct exynos_drm_manager
  drm/exynos: add pipe param to exynos_drm_crtc_create()
  drm/exynos: rename base object of struct exynos_drm_crtc to 'base'
  drm/exynos: remove exynos_drm_crtc_mode_set_commit()
  drm/exynos: call exynos_update_plane() directly on page flips
  drm/exynos: unify plane update on exynos_update_plane()
  drm/exynos: remove exynos_plane_commit() wrapper
  drm/exynos: don't do any DPMS operation while updating planes
  drm/exynos: Don't touch DPMS when updating overlay planes
  drm/exynos/vidi: remove useless ops->commit()
  drm/exynos/fimd: don't initialize 'ret' variable in fimd_probe()
  drm/exynos: remove struct exynos_drm_overlay
  drm/exynos: remove exynos_drm_crtc_plane_* wrappers
