* 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:
