+* Marvell 88pm80x Power Management IC
+
+Required parent device properties:
+- compatible : "marvell,88pm80x"
+- reg : the I2C slave address for the 88pm80x chip
+- interrupts : IRQ line for the 88pm80x chip
+- interrupt-controller: describes the 88pm80x as an interrupt controller (has
its own domain)
+- #interrupt-cells : should be 1.
+ - The cell is the 88pm80x local IRQ number
+
+Optional parent device properties:
+- marvell,88pm80x-irqmode: inicates whether interrupt status is cleared by read
+- marvell,88pm80x-poweraddr: 88pm80x are multi-chips solution. <reg> stores
the I2C address
+ of one chip, and this property stores the I2C
address of
+ power related chip.
+- marvell,88pm80x-gpadcaddr: 88pm80x are multi-chips solution. <reg> stores
the I2C address
+ of one chip, and this property stores the I2C
address of
+ gpadc related chip.
+
+88pm80x consists of various groups of sub-devices:
+
+Device Supply Names Description
+------ ------------ -----------
+88pm80x-onkey : : On key
+88pm80x-rtc : : RTC
+
+Example:
+ pmic: 88pm800@30 {
+ compatible = "marvell,88pm80x";
+ reg = <0x30>;
+ interrupts = <4>;
+ interrupt-parent = <&intc>;
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ marvell,88pm80x-irqmode = 0;
+ marvell,88pm80x-poweraddr = <0x31>;
+ marvell,88pm80x-gpadcaddr = <0x32>;
+ };
+
+
+ pmic: 88pm805@38 {
+ compatible = "marvell,88pm80x";
+ reg = <0x38>;
+ interrupts = <124>;
+ interrupt-parent = <&gpio>;
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ marvell,88pm80x-irqmode = 0;
