-OMAP PRM instance bindings
-
-Power and Reset Manager is an IP block on OMAP family of devices which
-handle the power domains and their current state, and provide reset
-handling for the domains and/or separate IP blocks under the power domain

-
-Required properties:
-- compatible:	Must contain one of the following:
-		"ti,am3-prm-inst"
-		"ti,am4-prm-inst"
-		"ti,omap4-prm-inst"
-		"ti,omap5-prm-inst"
-		"ti,dra7-prm-inst"
-		and additionally must contain:
-		"ti,omap-prm-inst"
-- reg:		Contains PRM instance register address range
-		(base address and length)
-
-Optional properties:
-- #power-domain-cells:	Should be 0 if the instance is a power domain provider.
-- #reset-cells:	Should be 1 if the PRM instance in question supports resets.

-Example:
-
