Subject[PATCH v8 0/3] Mediatek MT8173 CMDQ support


This is Mediatek MT8173 Command Queue(CMDQ) driver. The CMDQ is used
to help read/write registers with critical time limitation, such as
updating display configuration during the vblank. It controls Global
Command Engine (GCE) hardware to achieve this requirement.

These patches have a build dependency on top of v4.6-rc1.

Changes since v7:
- fix one v6 bug and one v7 bug, which are due to rewriting for coding style
- use flushing work queue instead of killing active tasks in suspend and
merge suspend/resume protection patch into CMDQ driver patch
- refine some code accroding to comments for v7

Best regards,
HS Liao
