+* Texas Instruments - LM3633 Lighting Power Solution for Smartphone Handsets
+
+The LM3633 is a complete power source for
+backlight, keypad, and indicator LEDs in smartphone
+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:
+	- runtime-ramp-up-msec: Current ramping from one brightness level to
+				the a higher brightness level.
+				Range from 2048 us - 117.44 s
+	- runtime-ramp-down-msec: Current ramping from one brightness level to
+				  the a lower brightness level.
+				  Range from 2048 us - 117.44 s
+	- label : see Documentation/devicetree/bindings/leds/common.txt
+	- linux,default-trigger :
+	   see Documentation/devicetree/bindings/leds/common.txt
+
+Example:
+Control bank C output to 3 LVLEDs and Control F, G and H have independent
+controls of the LVLEDs.
