Message

The CMDQ (Command Queue) in MT8183 is used to help
update all relevant display controller registers
with critical time limation.

These patched add CMDQ interface in ddp_comp interface
and add CMDQ control flow.

This patch depends on ptach:
drm/mediatek: fixup cursor moving unsmooth issue
(https://patchwork.kernel.org/cover/11123119/)
add drm support for MT8183
(https://patchwork.kernel.org/cover/11121519/)
support gce on mt8183 platform
(https://patchwork.kernel.org/cover/11120153/)
