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 LM3633 dt binding needs to be moved from the ti-lmu.txt and a dedicated LED dt binding needs to be added. The new LM3633 LED dt binding will then reside in the Documentation/devicetree/bindings/leds directory and follow the current LED and general bindings guidelines.
