+
+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
+hierarchy.
+
+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:
+- #reset-cells: Should be 1 if the PRM instance in question supports resets.
+
+Example:
+
+prm_dsp2: prm@1b00 {
+ compatible = "ti,omap-prm-inst", "ti,dra7-prm-inst";
+ reg = <0x1b00 0x40>;
+ #reset-cells = <1>;
