[PATCH v14 0/4] Mediatek MT8173 CMDQ support

[HS Liao]

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 v4.8-rc1.

Changes since v13:
 - move to mailbox folder
 - simplify cmdq_thread_is_in_wfe

Best regards,
HS Liao
