[PATCH v17 0/4] Mediatek MT8173 CMDQ support
From: HS Liao
Date: Wed Nov 23 2016 - 03:42:53 EST
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 v4.9-rc1.
Changes since v16:
- merge suspend/resume patch into cmdq driver patch
- merge power saving patch into cmdq driver patch
- split cmdq mailbox controller and cmdq helper into two different patches
Best regards,
HS Liao
