+LEDs connected to tcl59116
+
+Required properties
+- compatible: should be "ti,tlc59116"
+- #address-cells: must be 1
+- #size-cells: must be 0
+- reg: typically 0x68
+
+Each led is represented as a sub-node of the ti,,tlc59116.
+See Documentation/devicetree/bindings/leds/common.txt
+
+LED sub-node properties:
+- reg: number of LED line, 0 to 15
+- label: (optional) name of LED
+- linux,default-trigger : (optional)
+
+Examples:
+
+tlc59116@68 {
+	#address-cells = <1>;
+	#size-cells = <0>;
+	compatible = "ti,tlc59116";
+	reg = <0x68>;
+
+	wan@0 {
+		label = "wrt1900ac:amber:wan";
+		reg = <0x0>;
+	};
+
+	2g@2 {
+		label = "wrt1900ac:white:2g";
+		reg = <0x2>;
+	};
+
+	alive@9 {
+		label = "wrt1900ac:green:alive";
+		reg = <0x9>;
+		linux,default_trigger = "heartbeat";
