[PATCH 6/7] arm64: zynqmp: Enable iio-hwmon for ina226 on zcu106

Michal Simek michal.simek at xilinx.com
Thu Jan 9 06:02:20 PST 2020


ina226 hwmon driver is deprecated and it is recommended to use new iio
based driver. The patch is enabling iio-hwmon driver to export
functionality from IIO to hwmon interface to be able to use lm-sensors
package.
