+LEDs connected to tca6507
+
+Required properties:
+- compatible : should be : "ti,tca6507".
+- #address-cells: must be 1
+- #size-cells: must be 0
+- reg: typically 0x45.
+
+Optional properties:
+- gpio-controller: allows lines to be used as output-only GPIOs.
+- #gpio-cells: if present, must not be 0.
+
+Each led is represented as a sub-node of the ti,tca6507 device.
+
+LED sub-node properties:
+- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
+- reg : number of LED line (could be from 0 to 6)
+- linux,default-trigger : (optional)
+   see Documentation/devicetree/bindings/leds/common.txt
+- compatible: either "led" (the default) or "gpio".
+
+Examples:
+
+tca6507@45 {
+       compatible = "ti,tca6507";
+       #address-cells = <1>;
+       #size-cells = <0>;
+       reg = <0x45>;
+
+       gpio-controller;
+       #gpio-cells = <2>;
+
+       led0: red-aux@0 {
+               label = "red:aux";
+               reg = <0x0>;
+       };
+
+       led1: green-aux@1 {
+               label = "green:aux";
+               reg = <0x5>;
+               linux,default-trigger = "default-on";
+       };
+
+       wifi-reset@6 {
+               reg = <0x6>;
+               compatible = "gpio";
+       };
