Subject: [PATCH v2 0/6] Add RSC power domain support
Date: Fri, 23 Aug 2019 13:46:57 +0530	[thread overview]
Message-ID: <20190823081703.17325-1-mkshah@codeaurora.org> (raw)

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[1], 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.
