leds: Add device tree binding for pca9633
Similar to tca6507, we can just parse the standard LED properties for pca9633. Tested on a pca9632, which is compatible with pca9633. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>

+LEDs connected to pca9633 or pca9632
+
+Required properties:
+- compatible : should be : "nxp,pca963x"
+
+Optional properties:
+- nxp,totem-pole : use totem pole (push-pull) instead of default open-drain
+
+Each led is represented as a sub-node of the nxp,pca9633 device.
+
+LED sub-node properties:
+- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
+- reg : number of LED line (could be from 0 to 4)
+- linux,default-trigger : (optional)
+ see Documentation/devicetree/bindings/leds/common.txt
+
+Examples:
+
+pca9632: pca9632 {
+ compatible = "nxp,pca9632", "nxp,pca963x";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x62>;
+
+ red@0 {
+ label = "red";
+ reg = <0>;
+ linux,default-trigger = "none";
+ };
+ green@1 {
+ label = "green";
+ reg = <1>;
+ linux,default-trigger = "none";
+ };
+ blue@2 {
+ label = "blue";
+ reg = <2>;
+ linux,default-trigger = "none";
+ };
+ unused@3 {
+ label = "unused";
+ reg = <3>;
+ linux,default-trigger = "none";
+ };
