Subject: [PATCH v4 0/2] Allow imx6qp PU domain off in suspend
Date: Fri, 26 Apr 2019 21:38:13 +0000	[thread overview]
Message-ID: <cover.1556313614.git.leonard.crestez@nxp.com> (raw)

On imx6qp power gating on the PU domain is disabled because of errata
ERR009619. However power gating during suspend/resume can still be
performed.

Implemented with a new core flag because otherwise distinguishing
between "runtime off" and "suspend off" is very complicated.

Link to v3 for previous attempt: https://lkml.org/lkml/2018/7/6/698

The imx vendor tree has been doing this for a many years but it uses
direct calls from platform suspend to GPC driver.

Link to v1 for similar attempt: https://lkml.org/lkml/2018/7/2/357
