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.

Note that the lowest numbered temperature zone trip point corresponds to

to the border between the highest and one but highest temperature zones, and

vica versa. So the temperature zone trip points 1-4 (or 1-2) go from high temp

mimicks this.
