Subject: arm64: zynqmp: Enable iio-hwmon for ina226 on zcu102
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=faddcbe7d7db47600f3da3b5860423b7b5081ca7;p=u-boot.git

arm64: zynqmp: Enable iio-hwmon for ina226 on zcu102

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.
