From 7669896f499e1bce5cfb38f2685ff583ecdb24dd Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 9 Dec 2009 20:36:01 +0100 Subject: hwmon: (f71882fg) Add support for the f71889fg (version 2) This adds support for the Fintek f71889fg to the f71882fg driver, many thanks to Gerd v. Egidy for providing (remote) access to a machine which such an ic. Note that this bit of the patch: - val = SENSORS_LIMIT(val, 0, 255); + + if (data->type == f71889fg) + val = SENSORS_LIMIT(val, -128, 127); + else + val = SENSORS_LIMIT(val, 0, 127); Changes behaviour for already supported models, the new behaviour is correct as the already supported models have bit 7 of the involved registers fixed at 0, so the previous behaviour which allowed setting temp zone limits > 127 was not correct.
