[PATCH 0/2] hwmon: ina2xx: convert driver to using regmap

Hi Guenter,

as requested, here's the regmap version as a separate patch. I've left out
the idea of separate show functions as it doesn't bring much indeed.

If you're interested in a before/after comparison, here are the plots of
of a usb key (DUT) power-cycle captured using either driver version.
As expected, the measurement is better resolved with single reads.

Many thanks.

hwmon: ina2xx: give precedence to DT over checking for platform data.
