The way these systems are configured, I don't know if you can do what
you want without generating a custom device tree.

The leds class has a trigger function and can be tied to various GPIO
pins, but I believe that conflicts with exporting that same GPIO pin.

If anyone knows of a way to do this without requiring customizing a
device tree to move GPIO pins from /sys/class/gpio to /sys/class/leds/
entries, or if there's a way to have both for the same pin, I'd love to
hear it!
