| 78if the device tree is used. 79 80Additionally ina226 supports update_interval attribute as described in 81Documentation/hwmon/sysfs-interface.rst. Internally the interval is the sum of 82bus and shunt voltage conversion times multiplied by the averaging rate. We 83don't touch the conversion times and only modify the number of averages. The 84lower limit of the update_interval is 2 ms, the upper limit is 2253 ms. 85The actual programmed interval may vary from the desired value. --- 38 unchanged lines hidden --- | 78if the device tree is used. 79 80Additionally ina226 supports update_interval attribute as described in 81Documentation/hwmon/sysfs-interface.rst.
