* Maxim max8925 Power Management IC
Required parent device properties:
- compatible : "maxim,max8925"
- reg : the I2C slave address for the max8925 chip
- interrupts : IRQ line for the max8925 chip
- interrupt-controller: describes the max8925 as an interrupt
controller (has its own domain)
- #interrupt-cells : should be 1.
- The cell is the max8925 local IRQ number
Optional parent device properties:
- maxim,tsc-irq: there are 2 IRQ lines for max8925, one is indicated in
interrupts property, the other is indicated here.
max8925 consists of a large and varied group of sub-devices:
Device Supply Names Description
------ ------------ -----------
max8925-onkey : : On key
max8925-rtc : : RTC
max8925-regulator : : Regulators
max8925-backlight : : Backlight
max8925-touch : : Touchscreen
max8925-power : : Charger
