The PGC that is part of GPC controls isolation and power sequencing of the PU power domain. The power domain will be handled by the generic pm domain framework and needs a phandle to the PU regulator to turn off power when the domain is disabled.

It's time to have a binding doc for gpc/pgc? And I'm not sure "fsl,power-domain" is a good compatible as it's so generic. Shawn
