+* 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 uA to 30 mA.

+* 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:

+
+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

+* Single Byte SPI LED Device Driver.
+
+The driver can be used for controllers with a very simple SPI protocol:
+- one LED is controlled by a single byte on MOSI
+- the value of the byte gives the brightness between two values (lowest to
+  highest)
+- no return value is necessary (no MISO signal)
+
+The value for lowest and highest brightness is dependent on the device and
+therefore on the compatible string.
+
+Depending on the compatible string some special functions (like hardware
+accelerated blinking) might can be supported too.
+
+The driver currently only supports one LED. The properties of the LED are
+configured in a sub-node in the device node.
+
+Required properties:
+- compatible: should be one of
+   * "ubnt,acb-spi-led"		microcontroller (SONiX 8F26E611LA) based device
+				used for example in Ubiquiti airCube ISP
+
+Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
+apply.
+
+LED sub-node properties:
+- label:
+	see Documentation/devicetree/bindings/leds/common.txt
+- default-state:
+	see Documentation/devicetree/bindings/leds/common.txt
+	Only "on" and "off" are supported.
+
+Example:
+
+led-controller@0 {
+	compatible = "ubnt,acb-spi-led";
+	reg = <0>;
+	spi-max-frequency = <100000>;
+
+	led {
