| 2 | |
| 3 | The LP8860-Q1 is an high-efficiency LED |
| 4 | driver with boost controller. It has 4 high-precision |
| 5 | current sinks that can be controlled by a PWM input |
| 6 | signal, a SPI/I2C master, or both. |
| 7 | |
| 8 | Required properties: |
| 9 | - compatible : |
| 10 | "ti,lp8860" |
| 11 | - reg : I2C slave address |
| 12 | - #address-cells : 1 |
| 13 | - #size-cells : 0 |
| 14 | |
| 15 | Optional properties: |
| 16 | - enable-gpios : gpio pin to enable (active high)/disable the device. |
| 17 | - vled-supply : LED supply |
