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.

Changes since v20:
-rebase to v4.15-rc1
-move dma_map_single outside of spinlock
Changes since v19:
-rebase to v4.10-rc2
