1 LEDs connected to pca9632, pca9633 or pca9634
4 - compatible : should be : "nxp,pca9632", "nxp,pca9633", "nxp,pca9634" or "nxp,pca9635"
7 - nxp,totem-pole : use totem pole (push-pull) instead of open-drain (pca9632 defaults
8 to open-drain, newer chips to totem pole)
9 - nxp,hw-blink : use hardware blinking instead of software blinking
11 Each led is represented as a sub-node of the nxp,pca963x device.
13 LED sub-node properties:
14 - label : (optional) see Documentation/devicetree/bindings/leds/common.txt
15 - reg : number of LED line (could be from 0 to 3 in pca9632 or pca9633,
16 0 to 7 in pca9634, or 0 to 15 in pca9635)
17 - linux,default-trigger : (optional)
18 see Documentation/devicetree/bindings/leds/common.txt
