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.
