What: /sys/bus/iio/devices/iio:deviceX/in_power_shunt_resistor Date: March 2017 KernelVersion: 4.12 Contact: linux-iio@vger.kernel.org Description: The value of the shunt resistor used to compute power drain on common input voltage pin (RS+). In Ohms. What: /sys/bus/iio/devices/iio:deviceX/in_current_shunt_resistor Date: March 2017 KernelVersion: 4.12 Contact: linux-iio@vger.kernel.org Description: The value of the shunt resistor used to compute current flowing between RS+ and RS- voltage sense inputs. In Ohms. These attributes describe a single physical component, exposed as two distinct attributes as it is used to calculate two different values: power load and current flowing between RS+ and RS- inputs.
