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 : |
