* 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:
- label: see Documentation/devicetree/bindings/leds/common.txt
- linux,default-trigger: see Documentation/devicetree/bindings/leds/common.txt
Example:
led-controller@30 {
compatible = "panasonic,an30259a";
reg = <0x30>;
#address-cells = <1>;
#size-cells = <0>;
led@1 {
reg = <1>;
linux,default-trigger = "heartbeat";
label = "red:indicator";
};
led@2 {
reg = <2>;
label = "green:indicator";
};
led@3 {
reg = <3>;
label = "blue:indicator";
};
};
