Hi!
Now that we have support for GPIO lines of the SMARC connector, enable
LED support on the KBox A-230-LS. There are two LEDs without fixed
functions, one is yellow and one is green. Unfortunately, it is just one
multi-color LED, thus while it is possible to enable both at the same
time it is hard to tell the difference between "yellow only" and "yellow
and green".
+		user_yellow {
+			label = "s1914:yellow:user";
+			gpios = <&sl28cpld_gpio0 0 0>;
+		};
+
+		user_green {
+			label = "s1914:green:user";
+			gpios = <&sl28cpld_gpio1 3 0>;
+		};
This is not suitable label for such LEDs... there's zero chance userland will
know what to do with these.

Do they have some kind of "usual" function?

Best regards,
									Pavel
