+* Si-En Technology - SN3218 18-Channel LED Driver
+
+Required properties:
+- compatible :
+ "si-en,sn3218"
+- address-cells : must be 1
+- size-cells : must be 0
+- reg : I2C slave address, typically 0x54
+
+There must be at least 1 LED which is represented as a sub-node
+of the sn3218 device.
+
+LED sub-node properties:
+- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
+- reg : number of LED line (could be from 0 to 17)
+- linux,default-trigger : (optional)
+ see Documentation/devicetree/bindings/leds/common.txt
+
+Example:
+
+sn3218: led-controller@54 {
+ compatible = "si-en,sn3218";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x54>;
+
+ led@0 {
+ label = "led1";
+ reg = <0x0>;
+ };
+
+ led@1 {
+ label = "led2";
+ reg = <0x1>;
+ };
+
+ led@2 {
+ label = "led3";
+ reg = <0x2>;
+ };
+};
