[PATCH 1/7] arm64: zynqmp: Enable iio-hwmon for ina226 on zcu100

From: Michal Simek
Date: Thu Jan 09 2020 - 09:02:41 EST


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.
