So this is just a GPIO client like any such thing right?

I mean this thing has nothing more to do with the GPIO subsystem
than say, drivers/input/keyboard/gpio_keys.c?

So from the GPIO subsystem point of view controlling power is
an alien concept.

But I suspect Anton may be ready to welcome a driver like this
under drivers/power/* which I think is where it belongs.
