Subject: [PATCH v10 0/4] 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 v4.7-rc1.

Changes since v9:
 - rename merge_wfe to atomic_exec
   atomic_exec should merge wfe (wait for event) commands and prevent
   to suspend gce when gce starts to execute commands after wfe.
 - merge cmdq_rec into cmdq_task since command buffer allocation for
   cmdq_task had been modified to the same as cmdq_rec in CMDQ v9
 - refine mailbox part in device tree binding document

Best regards,
HS Liao
