| 2 | |
| 3 | Required parent device properties: |
| 4 | - compatible : "maxim,max8925" |
| 5 | - reg : the I2C slave address for the max8925 chip |
| 6 | - interrupts : IRQ line for the max8925 chip |
| 7 | - interrupt-controller: describes the max8925 as an interrupt |
| 8 | controller (has its own domain) |
| 9 | - #interrupt-cells : should be 1. |
| 10 | - The cell is the max8925 local IRQ number |
| 11 | |
| 12 | Optional parent device properties: |
| 13 | - maxim,tsc-irq: there are 2 IRQ lines for max8925, one is indicated in |
| 14 | interrupts property, the other is indicated here. |
| 15 | |
| 16 | max8925 consists of a large and varied group of sub-devices: |
| 17 | |
| 18 | Device Supply Names Description |
| 19 | ------ ------------ ----------- |
| 20 | max8925-onkey : : On key |
| 21 | max8925-rtc : : RTC |
| 22 | max8925-regulator : : Regulators |
| 23 | max8925-backlight : : Backlight |
| 24 | max8925-touch : : Touchscreen |
| 25 | max8925-power : : Charger |
| 26 | |
