+* Marvell 88PM860x Power Management IC
+
+Required parent device properties:
+- compatible : "marvell,88pm860x"
+- reg : the I2C slave address for the 88pm860x chip
+- interrupts : IRQ line for the 88pm860x chip
+- interrupt-controller: describes the 88pm860x as an interrupt controller (has its own domain)
+- #interrupt-cells : should be 1.
+ - The cell is the 88pm860x local IRQ number
+
+Optional parent device properties:
+- marvell,88pm860x-irq-read-clr: inicates whether interrupt status is cleared by read
+- marvell,88pm860x-slave-addr: 88pm860x are two chips solution. <reg> stores the I2C address
+ of one chip, and this property stores the I2C address of
+ another chip.
+
+88pm860x consists of a large and varied group of sub-devices:
