+* Marvell 88PM8xx Power Management IC
+
+Required parent device properties:
+- compatible : "marvell,88pm800", "marvell,88pm805", "marvell,88pm860"
+- reg : the I2C slave address for the 88pm8xx chip
+- interrupts : IRQ line for the 88pm8xx chip
+- interrupt-controller: describes the 88pm8xx as an interrupt controller
+- #interrupt-cells : should be 1.
+ - The cell is the 88pm8xx local IRQ number
+
+Optional parent device properties:
+- marvell,irq-clr-on-write: indicates whether interrupt status is cleared
+ by write or read.
+ If enabled, interrupt is cleared by write else just read would do.
+
+88pm8xx family of devices consists of varied group of sub-devices:
+
+Device Supply Names Description
+------ ------------ -----------
+88pm80x-onkey : : On key
+88pm80x-rtc : : RTC
+88pm80x-regulator : : Regulators
+
+Note: More device list will follow
+
+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>;
+
+ marvell,irq-clr-on-write;
+
+ regulators {
+ compatible = "marvell,88pm80x-regulator";
+
+ buck1a: BUCK1A {
+ regulator-name = "BUCK1A";
+ regulator-min-microvolt = <600000>;
+ regulator-max-microvolt = <1800000>;
+ regulator-boot-on;
+ regulator-always-on;
+ };
+ ldo1: LDO1 {
+ regulator-name = "LDO1";
+ regulator-min-microvolt = <1700000>;
+ regulator-max-microvolt = <3300000>;
+ regulator-boot-on;
+ regulator-always-on;
+ };
+ };
+
+ rtc {
+ compatible = "marvell,88pm80x-rtc";
+ };
+ };
