1	LEDs connected to pca9632, pca9633 or pca9634
2	
3	Required properties:
4	- compatible : should be : "nxp,pca9632", "nxp,pca9633" or "nxp,pca9634"
5	
6	Optional properties:
7	- nxp,totem-pole : use totem pole (push-pull) instead of default open-drain
8	- nxp,hw-blink : use hardware blinking instead of software blinking
9	
10	Each led is represented as a sub-node of the nxp,pca963x device.
11	
12	LED sub-node properties:
13	- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
14	- reg : number of LED line (could be from 0 to 3  in pca9632 or pca9633
15			or 0 to 7 in pca9634)
16	- linux,default-trigger : (optional)
17	   see Documentation/devicetree/bindings/leds/common.txt

19	Examples:
20	
21	pca9632: pca9632 {
22		compatible = "nxp,pca9632";
23		#address-cells = <1>;
