Subject: [PATCH 0/2] hwmon: ina2xx: convert driver to using regmap
Date: Mon, 26 Oct 2015 17:24:31 +0100 [thread overview]
Message-ID: <1445876673-32180-1-git-send-email-mtitinger@baylibre.com> (raw)
In-Reply-To: <562B7D56.3010700@roeck-us.net>
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.
