Any entity that is involved in power management is referred to as a node. The following sections describe how the platform management works with slave nodes allocated to each subsystem instead of the APU and the RPU.

Generally, the APU or the RPU inform the PMC about their usage of a slave node, by requesting for it. The PMC is then informed about the capability requirement needed from the slave node. At this point, the PMC powers up the slave node, so it can be initialized by the APU or the RPU.
