* 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 :
