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

to low temp! This is how things are implemented in the IC, and the driver

mimicks this.

There are 2 modes to specify the speed of the fan, PWM duty cycle (or DC

voltage) mode, where 0-100% duty cycle (0-100% of 12V) is specified. And RPM
