Subject: [PATCH v1 0/6] drm/mediatek: fix cursor issue and apply CMDQ in

The CMDQ (Command Queue) in MT8183 is used to help update all
relevant display controller registers with critical time limation.
This patch add cmdq interface in ddp_comp interface, let all
ddp_comp interface can support cpu/cmdq function at the same time.

These patches also can fixup cursor moving is not smooth
when heavy load in webgl.

This patch depends on ptach:
add drm support for MT8183
(https://patchwork.kernel.org/cover/11121519/)
support gce on mt8183 platform
(https://patchwork.kernel.org/cover/11255147)
drm/mediatek: Refactor plane init/check and support rotation
(https://pw-emeril.freedesktop.org/series/69015/)
drm/mediatek: Check return value of mtk_drm_ddp_comp_for_plane
(https://lore.kernel.org/patchwork/patch/1154517/)

Changes since v0:
 - remove redundant code
 - remove patch
   "drm/mediatek: fix atomic_state reference counting"
   After remove this patch, the issue we met before is gone.
   So I do not add any extra code to do something.

Bibby Hsieh (6):
  drm/mediatek: put "event" in critical section
  drm/mediatek: use DRM core's atomic commit helper
  drm/mediatek: handle events when enabling/disabling crtc
  drm/mediatek: update cursors by using async atomic update
  drm/mediatek: support CMDQ interface in ddp component
  drm/mediatek: apply CMDQ control flow
