+* Multicolor LED properties
+
+Bindings for multi color LEDs show how to describe current outputs of
+either integrated multi-color LED elements (like RGB, RGBW, RGBWA-UV
+etc.) or standalone LEDs, to achieve logically grouped multi-color LED
+modules. This is achieved by adding multi-led nodes layer to the
+monochrome LED bindings.
+
+The nodes and properties defined in this document are unique to the multicolor
+LED class.  Common LED nodes and properties are inherited from the common.txt
+within this documentation directory.
+
+Required LED child properties:
+	- color : For multicolor LED support this property should be defined as
+		  LED_COLOR_ID_MULTI and further definition can be found in
+		  include/linux/leds/common.h.
