Subject: [PATCH v16 1/5] iommu/arm-smmu: Add pm_runtime/sleep ops
Date: Thu, 30 Aug 2018 20:15:37 +0530	[thread overview]
Message-ID: <20180830144541.17740-2-vivek.gautam@codeaurora.org> (raw)
In-Reply-To: <20180830144541.17740-1-vivek.gautam-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>

From: Sricharan R <sricharan-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>

The smmu needs to be functional only when the respective
master's using it are active. The device_link feature
helps to track such functional dependencies, so that the
iommu gets powered when the master device enables itself
using pm_runtime. So by adapting the smmu driver for
runtime pm, above said dependency can be addressed.

This patch adds the pm runtime/sleep callbacks to the
driver and also the functions to parse the smmu clocks
from DT and enable them in resume/suspend.

Also, while we enable the runtime pm add a pm sleep suspend
callback that pushes devices to low power state by turning
the clocks off in a system sleep.
Also add corresponding clock enable path in resume callback.
