Changes in v5: - Add Rob's Acked by on dt-bindings change - Drop firmware psci change - Update cpuidle stats in dtsi to follow PC mode - Include change to update dirty flag when data is updated from [4] - Add change to invoke rpmh_flush when caches are dirty Changes in v4: - Add change to allow hierarchical topology in PC mode - Drop hierarchical domain idle states converter from v3 - Address Merge sc7180 dtsi change to add low power modes 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 various resources.
