+* Multicolor LED properties
+
+Monochrome LEDs can grouped into LED clusters. These clusters can provide a
+visible output that have a wide range of colors and intensities.
Here is the same issue as I spotted in a review for the patch 2/9
from this set:
"
I'd say it won't be the most frequent use case. We can expect rather
compound RGB, RGBA[UV] etc. LED elements being connected to iouts of
multi color LED controllers like LP50xx.
"
How about:
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.
