+* Texas Instruments LM36274 4-Channel LCD Backlight Driver w/Integrated Bias
+
+The LM36274 is an integrated four-channel WLED driver and LCD bias supply.
+The backlight boost provides the power to bias four parallel LED strings with
+up to 29V total output voltage. The 11-bit LED current is programmable via
+the I2C bus and/or controlled via a logic level PWM input from 60 μA to 30 mA.
+
+Parent device properties are documented in ../mfd/ti_lmu.txt
+Regulator properties are documented in ../regulator/lm363x-regulator.txt
+
+Required backlight properties:
+	- compatible:
+		"ti,lm36274-backlight"
+	- reg : 0
+	- #address-cells : 1
+	- #size-cells : 0
+	- led-sources : Indicates which LED strings will be enabled.
+			Values from 0-3, sources is 0 based so strings will be
+			source value + 1.
+
+Optional backlight properties:
+	- 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.
