[RFC v2 0/3] Mediatek MT8173 CMDQ support

[HS Liao <hs.liao@mediatek.com>]

Hi,

This is Mediatek MT8173 Command Queue(CMDQ) driver. The CMDQ is used
to help read/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 v4.5-rc1.

Changes since v1:
 - update device tree binding doc
 - use void* for base address
 - use size_t for "size in bytes"
 - use cmdq_thread instead of thread id
 - use flags instead of scenarios
 - call cmdq_event_reset() in suitable places
 - use ktime instead of sched_clock
 - use struct device instead of struct platform_device if possible
 - rename recorder to record
 - correct some typos and remove some useless code

Best regards,
HS Liao
