| * 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 |
| |
