+LEDs conected to tca6507
+
+Required properties:
+- compatible : should be : "ti,tca6507".
+
+Each led is represented as a sub-node of the ti,tca6507 device.
+
+LED sub-node properties:
+- label : label for this LED
+- reg : number of LED line (could be from 0 to 6)
+- linux,default-trigger :  (optional) This parameter, if present, is a
+  string defining the trigger assigned to the LED.  Current triggers are:
+    "backlight" - LED will act as a back-light, controlled by the framebuffer
+		  system
+    "default-on" - LED will turn on
+    "heartbeat" - LED "double" flashes at a load average based rate
+    "ide-disk" - LED indicates disk activity
+    "timer" - LED flashes at a fixed, configurable rate
+
+Examples:
+
+tca6507@45 {
+	compatible = "ti,tca6507";
+	#address-cells = <1>;
+	#size-cells = <0>;
+	reg = <0x45>;
+
+	led0: red_aux@0 {
+		label = "red:aux";
+		reg = <0x0>;
+	};
+
+	led1: green_aux@1 {
+		label = "green:aux";
+		reg = <0x5>;
+		linux,default-trigger = "default-on";
+	};
+
+};
