1 * Marvell 88PM860x Power Management IC
2
3 Required parent device properties:
4 - compatible : "marvell,88pm860x"
5 - reg : the I2C slave address for the 88pm860x chip
6 - interrupts : IRQ line for the 88pm860x chip
7 - interrupt-controller: describes the 88pm860x as an interrupt controller (has its own domain)
8 - #interrupt-cells : should be 1.
9 - The cell is the 88pm860x local IRQ number
10
11 Optional parent device properties:
12 - marvell,88pm860x-irq-read-clr: inicates whether interrupt status is cleared by read
13 - marvell,88pm860x-slave-addr: 88pm860x are two chips solution. <reg> stores the I2C address
14 of one chip, and this property stores the I2C address of
15 another chip.

17 88pm860x consists of a large and varied group of sub-devices:
