+* 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";
+ };
+};
