From eff7687d473c31cba3876c13e97eebc708eb8582 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Fri, 4 Nov 2011 12:00:48 +0100 Subject: hwmon: (w83627ehf) Add support for the W83627UHG This is essentially a stripped down version of the W83627DHG. Noticeable difference is that it is still powered with +5V, as older models, even though the ADC resolution is 8 mV as newer models have. Thanks to Ulf Bruman (Saab Group) for doing all the testing.
