Configuring shunt_resistor in hwmon

[Vijay Khemka]

You should be able to define this value in device tree. Or you can calculate scale factor and use it in entity manager.

Subject: Configuring shunt_resistor in hwmon

Hi OpenBMC folks,

Is there a way to configure the shunt_resistor value for a hwmon with entity-manager or other modules? We need to configure this value to make the INA230 report correct voltage, but for now I don't find anything in the code for it. Shall this be a feature to implement? Thanks!
