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