I am still not sure whether in_currentY_shunt_resistor, in_powerY_shunt_resistor and in_energyY_shunt_resistor, should be added or not until a new driver using it comes through. Regarding pac1921, would it be more clear to expose a single in_shunt_resistor (keeping [dir_] for consistency as you suggested) as it is for ina2xx or in_current_shunt_resistor plus in_power_shunt_resistor as it is for max9611? I agree that just exposing it once would be more clear for the user, so I would go for the first case but maybe I am missing something. > > Thanks, > > Jonathan > Thanks, Matteo
