+actually consists from 5 LEDs that exposed by protocol like one LED.

+
+Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
+apply. In particular, "reg" and "spi-max-frequency" properties must be given.

You missed this in my v7 comments you should remove the label property.
