Subject: [PATCH v16 0/5] Mediatek MT8173 CMDQ support


Hi,

This is Mediatek MT8173 Command Queue(CMDQ) driver. The CMDQ is used
to help 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 v4.9-rc1.

Changes since v15:
 - separate "suspend and resume" patch from "save energy" patch
 - don't stop running tasks in cmdq_suspend()
   (i.e. leave no running tasks guarantee to clients)

Best regards,
HS Liao
