Some power-measuring ADCs work together with power load switches which
allow to power-cycle measured devices.

An example use case would be measuring the power consumption of a
development board during boot using a power monitor such as TI INA226
and power-cycling the board remotely using a TPS229* power switch.

Add an iio driver for simple GPIO power switches and expose a sysfs
attribute allowing to toggle their state.

I don't get this, isn't this doing the same as
drivers/power/reset/gpio-poweroff.c
?

With the only difference that the latter uses the standard syscall
from pm_power_off to reboot the system instead of some random
sysfs file.

As far as I understand it, the TPS229 is used by Barzosz to poweroff
a remote system. The gpio-poweroff driver is used to poweroff the
local system.
