+Power subsystem for Freescale MX23/MX28
+
+Required properties:
+- compatible:
+  - "fsl,imx23-power" for MX23
+  - "fsl,imx28-power" for MX28
+- address-cells, size-cells, ranges: must be present as appropriate to
+  map children
+- reg: Address and length of the register set for the power subsystem.
+
+Optional properties;
+- interrupts: Interrupts used by the power subsystem
+
+Example for imx28:
+
+	power: power@80044000 {
+				compatible = "fsl,imx28-power";
+				#address-cells = <1>;
+				#size-cells = <1>;
+				reg = <0x80044000 0x2000>;
+				interrupts = <6>;
+				ranges;
+	}
