1* Panasonic AN30259A 3-channel LED driver
2
3The AN30259A is a LED controller capable of driving three LEDs independently. It supports
4constant current output and sloping current output modes. The chip is connected over I2C.
5
6Required properties:
7 - compatible: Must be "panasonic,an30259a".
8 - reg: I2C slave address.
9 - #address-cells: Must be 1.
10 - #size-cells: Must be 0.
11
12Each LED is represented as a sub-node of the panasonic,an30259a node.
13
14Required sub-node properties:
15 - reg: Pin that the LED is connected to. Must be 1, 2, or 3.
16
17Optional sub-node properties:
18 - function :
19 see Documentation/devicetree/bindings/leds/common.txt
20 - color :
21 see Documentation/devicetree/bindings/leds/common.txt
22 - label :
23 see Documentation/devicetree/bindings/leds/common.txt (deprecated)
24 - linux,default-trigger :
25 see Documentation/devicetree/bindings/leds/common.txt
