7 title: Common properties for the multicolor LED class.
10 - Andrew Davis <afd@ti.com>
13 Bindings for multi color LEDs show how to describe current outputs of
14 either integrated multi-color LED elements (like RGB, RGBW, RGBWA-UV
15 etc.) or standalone LEDs, to achieve logically grouped multi-color LED
16 modules. This is achieved by adding multi-led nodes layer to the
