You'd need to document new "control" file.

But hold on, it is not an only driver with this "user-or-hardware"
feature, and we want to have a common solution. And that solution is
probably to have "hw-charger" trigger _just for this_ LED.

I can easily take a driver that always handles it as a "user" LED, if
you can get ACKs from device tree people on the documentation patches.
