title: Common properties for the multicolor LED class.

description: |
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.

LED_COLOR_ID_MULTI which can be found in include/linux/leds/common.h.
