Well, so that's what the "gpio-poweroff" driver I wrote is. All it does is hook into the device model and DT and provide various poweroff hooks that poke GPIOs. I still don't understand how the regulator API is supposed to help in my particular case (whole-system poweroff). Additional advice would be highly appreciated.
