Hello, This patch adds virtual power domain handling. Some comments are needed if such approach has any sense. The goal is to know the state of devices residing in domain which is never gated or are gated only during sleep. I.e. in Exynos3250 SoC there is one domain which is only put into retention in LPD state and to enter it some devices (i.e. mmc host controller) have to be inactive. Using domains and runtime PM it would be able to give an information to PM core that the SoC is ready for deeper power state.
