| * Panasonic AN30259A 3-channel LED driver |
| |
| The AN30259A is a LED controller capable of driving three LEDs independently. It supports |
| constant current output and sloping current output modes. The chip is connected over I2C. |
| |
| Required properties: |
| - compatible: Must be "panasonic,an30259a". |
| - reg: I2C slave address. |
| - #address-cells: Must be 1. |
| - #size-cells: Must be 0. |
| |
| Each LED is represented as a sub-node of the panasonic,an30259a node. |
| |
| Required sub-node properties: |
| - reg: Pin that the LED is connected to. Must be 1, 2, or 3. |
| |
| Optional sub-node properties: |
| - function : |
| see Documentation/devicetree/bindings/leds/common.txt |
| - color : |
| see Documentation/devicetree/bindings/leds/common.txt |
| - label : |
| see Documentation/devicetree/bindings/leds/common.txt (deprecated) |
| - linux,default-trigger : |
| see Documentation/devicetree/bindings/leds/common.txt |
