+            Index of the LED on a controller. It can be used by drivers or
+            applications to map a logical LED to its real position on the
+            controller. For example, this allows to handle boards where the
+            LEDs in an array/strip are not wired following the LED order of

+            Channel to color mapping of a multicolor LED. If a LED supports
+            several colors, then the color-mapping property can be used to
+            describe how the hardware channels and the colors are mapped.
+
+            For example the channel to color mapping of RGB LEDs would be
+
+               color-mapping =
+                    <LED_COLOR_ID_RED>,
