| 2 | |
| 3 | Required properties: |
| 4 | - compatible: "ti,lp8732", "ti,lp8733" |
| 5 | - reg: I2C slave address. |
| 6 | - gpio-controller: Marks the device node as a GPIO Controller. |
| 7 | - #gpio-cells: Should be two. The first cell is the pin number and |
| 8 | the second cell is used to specify flags. |
| 9 | See ../gpio/gpio.txt for more information. |
| 10 | - xxx-in-supply: Phandle to parent supply node of each regulator |
| 11 | populated under regulators node. xxx can be |
| 12 | buck0, buck1, ldo0 or ldo1. |
| 13 | - regulators: List of child nodes that specify the regulator |
| 14 | initialization data. |
| 15 | Example: |
| 16 | |

| 18 | compatible = "ti,lp8733"; |
