+handsets.
+
+This device is suitable for display and keypad Lighting
+
+Required properties:
+ - compatible:
+ "ti,lm3633"
+ - reg : I2C slave address
+ - #address-cells : 1
+ - #size-cells : 0
+
+Optional properties:
+ - enable-gpios : GPIO pin to enable/disable the device
+ - vled-supply : LED supply
+
+Required child properties:
+ - reg : 0 - HVLED is Controlled by bank A
+ 1 - HVLED is Controlled by bank B
+ 2,3,4 - LVLED1, 2 and 3 are Controlled by bank C, D and E
+ 5,6,7 - LVLED4, 5 and 6 are Controlled by bank F, G and H
+ - led-sources : Indicates which LED string is associated to which
+ control bank.
+ 0 - LED is not active in this control bank
+ 1 - LED string is controlled by this control bank
+
+Optional child properties:
+ - label : see Documentation/devicetree/bindings/leds/common.txt
+ - linux,default-trigger :
+ see Documentation/devicetree/bindings/leds/common.txt
+
+Example:
+
+led-controller@36 {
+ compatible = "ti,lm3633";
+ reg = <0x36>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ enable-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
+ vled-supply = <&vbatt>;
+
+ led@0 {
+ reg = <0>;
+ led-sources = <1 0 1>;
+ label = "white:first_backlight_cluster";
+ linux,default-trigger = "backlight";
+ };
+
+ led@1 {
+ reg = <1>;
+ led-sources = <0 1 0>;
+ label = "white:second_backlight_cluster";
+ linux,default-trigger = "backlight";
+ };
+
+ led@2 {
+ reg = <2>;
+ led-sources = <0 1 0>;
+ label = "white:indicator1";
+ };
