Please refer to the Documentation/devicetree/bindings/i2c/ina2xx.txt for bindings if the device tree is used. + +Additionally ina226 supports update_interval attribute as described in +Documentation/hwmon/sysfs-interface. 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. |
