 The shunt value in micro-ohms can be set via platform data or device tree at
 compile-time or via the shunt_resistor attribute in sysfs at run-time. Please
 refer to the Documentation/devicetree/bindings/hwmon/ina2xx.txt for bindings

+in Documentation/hwmon/sysfs-interface.rst. Internally the interval is the sum
+of bus and shunt voltage conversion times multiplied by the averaging rate. We
 don't touch the conversion times and only modify the number of averages. The
 lower limit of the update_interval is 2 ms, the upper limit is 2253 ms.
 The actual programmed interval may vary from the desired value.
