+* Texas Instruments - LM3697 Highly Efficient White LED Driver
+
+The LM3697 11-bit LED driver provides high-
+performance backlight dimming for 1, 2, or 3 series
+LED strings while delivering up to 90% efficiency.
+
+This device is suitable for display and keypad lighting
+
+Required properties:
+	- compatible:
+		"ti,lm3697"
+	- 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 - LED is Controlled by bank A
+		1 - LED is Controlled by bank B
+	- led-sources : Indicates which HVLED string is associated to which
+			control bank.  This is a zero based property so
+			HVLED1 = 0, HVLED2 = 1, HVLED3 = 2.
+			Additional information is contained
+			in Documentation/devicetree/bindings/leds/common.txt
+
+Optional child properties:
+	- ti,brightness-resolution - see Documentation/devicetree/bindings/mfd/ti-lmu.txt
+	- ramp-up-us: see Documentation/devicetree/bindings/mfd/ti-lmu.txt
+	- ramp-down-us: see Documentation/devicetree/bindings/mfd/ti-lmu.txt
+	- label : see Documentation/devicetree/bindings/leds/common.txt
+	- linux,default-trigger :
+	   see Documentation/devicetree/bindings/leds/common.txt
+
+Example:
+
+HVLED string 1 and 3 are controlled by control bank A and HVLED 2 string is
+controlled by control bank B.
