Subject: [PATCH 2/7] arm64: zynqmp: Enable iio-hwmon for ina226 on zcu111
Date:   Thu,  9 Jan 2020 15:02:16 +0100
Message-Id: <cca3e4bbc5441bca051f274fe19c3328f0027eca.1578578535.git.michal.simek@xilinx.com>

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.
