 		(base address and length)
 
 Optional properties:
+- #power-domain-cells:	Should be 0 if the PRM instance is a power domain.
 - #reset-cells:	Should be 1 if the PRM instance in question supports resets.
+- clocks: Functional and interface clocks managed by the power domain
+- clock-names: Names for the clocks using "fck" and "ick" naming
 
 Example:

 	reg = <0x1b00 0x40>;
