mailbox: mediatek: cmdq: clear the event in cmdq initial flow

2019-09-17T05:40:05+00:00

GCE hardware stored event information in own internal sysram,
if the initial value in those sysram is not zero value
it will cause a situation that gce can wait the event immediately
after client ask gce to wait event but not really trigger the
corresponding hardware.

In order to make sure that the wait event function is
exactly correct, we need to clear the sysram value in
cmdq initial flow.

mailbox: mediatek: Add Mediatek CMDQ driver

2018-08-03T14:22:14+00:00

This patch is first version of Mediatek 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.
Currently, CMDQ only supports display related hardwares, but we expect
it can be extended to other hardwares for future requirements.
