1	LEDs connected to tca6507
2	
3	Required properties:
4	- compatible : should be : "ti,tca6507".
5	- #address-cells: must be 1
6	- #size-cells: must be 0
7	- reg: typically 0x45.
8	
9	Optional properties:
10	- gpio-controller: allows lines to be used as output-only GPIOs.
11	- #gpio-cells: if present, must be 0.
12	
13	Each led is represented as a sub-node of the ti,tca6507 device.
14	
15	LED sub-node properties:
16	- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
17	- reg : number of LED line (could be from 0 to 6)
18	- linux,default-trigger : (optional)
19	   see Documentation/devicetree/bindings/leds/common.txt
20	- compatible: either "led" (the default) or "gpio".
21	
22	Examples:
23	
24	tca6507@45 {
25		compatible = "ti,tca6507";
26		#address-cells = <1>;
27		#size-cells = <0>;
28		reg = <0x45>;
29	
30		gpio-controller;
31		#gpio-cells = <2>;
32	
33		led0: red-aux@0 {
34			label = "red:aux";
35			reg = <0x0>;
36		};
37	
38		led1: green-aux@1 {
39			label = "green:aux";
40			reg = <0x5>;
41			linux,default-trigger = "default-on";
42		};
43	
44		wifi-reset@6 {
45			reg = <0x6>;
46			compatible = "gpio";
47		};
48	};
