* 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:
