0001 * Marvell 88PM860x Power Management IC
0002
0003 Required parent device properties:
0004 - compatible : "marvell,88pm860x"
0005 - reg : the I2C slave address for the 88pm860x chip
0006 - interrupts : IRQ line for the 88pm860x chip
0007 - interrupt-controller: describes the 88pm860x as an interrupt controller (has its own domain)
0008 - #interrupt-cells : should be 1.
0009 - The cell is the 88pm860x local IRQ number
0010
0011 Optional parent device properties:
0012 - marvell,88pm860x-irq-read-clr: inicates whether interrupt status is cleared by read
0013 - marvell,88pm860x-slave-addr: 88pm860x are two chips solution. <reg> stores the I2C address
0014 of one chip, and this property stores the I2C address of
0015 another chip.
0016
0017 88pm860x consists of a large and varied group of sub-devices:
