In micro Ohms. Unfortunately this has ended up with a name that made me initially think it was the power rating of the resistor in question (why we'd want to know that I've no idea). We might need to make this even more explicit to avoid idiots like me ;) It's the shunt resistor for the power measurement so I think it should probably be... in_power_shunt_resistance > + > +What: /sys/bus/iio/devices/iio:deviceX/in_shunt_resistor_current > +Date: March 2017 > +KernelVersion: 4.12 > +Contact: linux-iio@xxxxxxxxxxxxxxx > +Description: The value of the shunt resistor used to compute current flowing > + between RS+ and RS- voltage sense inputs.
