(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:
prm_dsp2: prm@...0 {
