The LM3697 is a single function LED driver. The single function LED
driver needs to reside in the LED directory as a dedicated LED driver
and not as a MFD device. The device does have common brightness and ramp
features and those can be accomodated by a TI LMU framework.
The LM3697 dt binding needs to be moved from the ti-lmu.txt and a dedicated
LED dt binding needs to be added. The new LM3697 LED dt binding will then
reside in the Documentation/devicetree/bindings/leds directory and follow the
current LED and general bindings guidelines.

+* 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
+ - compatible:
+ - reg : I2C slave address
+ - #address-cells : 1
+ - #size-cells : 0
+ - 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:
+ - max_brightness - This determines whether to use 8 bit brightness mode
+ or 11 bit brightness mode. If this value is not
+ set the device is defaulted to the preferred 8bit
+ brightness mode per 184.108.40.206 of the data sheet.
+ The values are 255 (8bit) or 2047 (11bit).
