[RFC v2 0/3] Mediatek MT8173 CMDQ support

From: HS Liao
Date: Tue Mar 01 2016 - 08:30:07 EST



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
