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

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.
