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.
