X-Git-Tag: v2020.10~539^2~46
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3d82d7167f139e35418bbdb21afcc3f21bdc71d4;p=platform%2Fkernel%2Fu-boot.git

arm64: zynqmp: Enable iio-hwmon for ina226 on zcu104

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.
