Subject[PATCH v4 0/7] drm/mediatek: fix cursor issue and apply CMDQ in MTK DRM
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
support gce on mt8183 platform
drm/mediatek: Refactor plane init/check and support rotation
drm/mediatek: Check return value of mtk_drm_ddp_comp_for_plane

Changes since v3:
- remove redundant code and variable

Changes since v2:
- move some changes to another patch
- disable layer in atomic_disable()

Changes since v1:
- remove redundant code
- merge the duplicate code
- use async instead of cursor

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 (7):
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: disable all the planes in atomic_disable
drm/mediatek: remove unused external function
drm/mediatek: support CMDQ interface in ddp component
drm/mediatek: apply CMDQ control flow
