* 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:
|
|
|
|
