Indeed the driver (the device) is at the boundary between IIO and
HWMON. I was thinking to start with a simple driver (this one that is
more apropiate to be a HWMON) and add more functionality later (like
data buffering that is quite important for example if someone wants to
profile power consumtion of the procesor itself, or a pheriperic, or a
battery)
