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 v4.10-rc1.

Changes since v18:
 - add "select MAILBOX" into CMDQ helper
 - remove power saving part to prevent a potential bug

Best regards,
HS Liao
