Device supports the bus and shunt voltage monitoring. So even no
current. Also the warning/critical limit is for the voltage across shunt.

So should we only expose the shunt/bus voltage, no power/current?

I am thinking that user space should not know the platform and hence
shunt resistance and so exposing the current and power on bus is better
option.
