From: Chen-Yu Tsai <redacted> 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. Signed-off-by: Chen-Yu Tsai <redacted>
Acked-by: Jernej Skrabec <jernej.skrabec@gmail.com> Best regards, Jernej
