+* Marvell 88PM80x Power Management IC
+
+Required parent device properties:
+- compatible		: "marvell,88pm800", "marvell,88pm805", "marvell,88pm860"
+- reg			: the I2C slave address for the 88pm80x family chip
+- interrupts		: IRQ line for the 88pm80x family chip
+- interrupt-controller	: describes the 88pm80x family chip as an interrupt
+			  controller
+- #interrupt-cells 	: should be 1.
+			  The cell is the 88pm80x local IRQ number
+
+88pm80x family of devices consists of varied group of sub-devices:
+
+Device		 	Supply Names	 Description
+------		 	------------	 -----------
+88pm80x-onkey		:		: On key
+88pm80x-rtc		:		: RTC
+88pm80x-regulator	:		: Regulators
+
+Example:
+
+	pmic: 88pm800 at 30 {
+		compatible = "marvell,88pm800";
+		reg = <0x30>;
+		interrupts = <GIC_SPI 77 IRQ_TYPE_LEVEL_HIGH>;
+		interrupt-parent = <&gic>;
+		interrupt-controller;
+		#interrupt-cells = <1>;

+		regulators {
+			compatible = "marvell,88pm80x-regulator";

+				regulator-max-microvolt = <1800000>;
