> 
> The Radxa Cubie A5E has a 3-color LED. The green and blue LEDs are wired
> to GPIO pins on the SoC, and the green one is lit by default to serve as
> a power indicator. The red LED is wired to the M.2 slot.
> 
> Add device nodes for the green and blue LEDs.
> 
> A default "heartbeat" trigger is set for the green power LED, though in
> practice it might be better if it were inverted, i.e. lit most of the
> time.
