-* 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
