-* 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
-
-Example:
-
-#include <dt-bindings/leds/common.h>
-
-led-controller@30 {
-	compatible = "panasonic,an30259a";
-	reg = <0x30>;
-	#address-cells = <1>;
-	#size-cells = <0>;
-
-	led@1 {
-		reg = <1>;
-		linux,default-trigger = "heartbeat";
-		function = LED_FUNCTION_INDICATOR;
-		color = <LED_COLOR_ID_RED>;
-	};
-
-	led@2 {
-		reg = <2>;
-		function = LED_FUNCTION_INDICATOR;
-		color = <LED_COLOR_ID_GREEN>;
-	};
-
-	led@3 {
-		reg = <3>;
-		function = LED_FUNCTION_INDICATOR;
-		color = <LED_COLOR_ID_BLUE>;
-	};
-};
