Subject: [PATCH v3 0/7] Add RSC power domain support
Date:   Mon,  3 Feb 2020 19:05:33 +0530
Message-Id: <1580736940-6985-1-git-send-email-mkshah@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Changes in v3:
- Address Rob's comment on dt property value
- Address Stephen's comments on rpmh-rsc driver change
- Include sc7180 cpuidle low power mode changes from [1]
- Include hierarchical domain idle states converter change from [2]

Changes in v2:
- Add Stephen's Reviewed-By to the first three patches
- Addressed Stephen's comments on fourth patch
- Include changes to connect rpmh domain to cpuidle and genpds

Resource State Coordinator (RSC) is responsible for powering off/lowering
the requirements from CPU subsystem for the associated hardware like buses,
clocks, and regulators when all CPUs and cluster is powered down.

RSC power domain uses last-man activities provided by genpd framework based on
Ulf Hansoon's patch series[3], when the cluster of CPUs enter deepest idle
states. As a part of domain poweroff, RSC can lower resource state requirements
by flushing the cached sleep and wake state votes for resources.
