Hi, Here is a much-simplified patch to restore automated fan control to the lm85 and clones in kernel 2.6.X. The associated patches for lm_sensors/lib/chips.h and lm_sensors/lib/chips.c will follow. Changes: It adheres as best as possible to the 3rd fan control interface proposal, using interface names like: tempN_auto_temp_[off|min|max|crit] pwmN_auto_pwm_[min|freq|minctl] pwmN_auto_channels Obviously a bit of translation is needed to fit the: Off --> Min --> Max --> Crit model to the native lm85 Min/Hyst/Range/Crit model, particularly as the Range is a set of discrete, non-uniformly-spaced temperature values. Because of the difference in models, every time tempN_auto_temp_min is adjusted, tempN_auto_temp_off and tempN_auto_temp_max must be recalculated, and new values assigned to Hyst and Range. Otherwise tempN_auto_temp_off and tempN_auto_temp_max would change in an unanticipated (to the user) manner, shifting up or down with corresponding changes in tempN_auto_temp_min. The code therefore maintains state in tempN_auto_temp_off_desired and tempN_auto_temp_max_desired, using these values to recalculate tempN_auto_temp_off and tempN_auto_temp_max whenever tempN_auto_temp_min varies. The adjusted "RANGE_TO_REG" function now finds the closest available match rather than simply picking the smallest value bigger than that requested. The last entry in lm85_range_map has been changed from 980 to 940 to match the value listed in the lm85 datasheet. I have changed the externally-visible magnitudes of the temperatures from .1C to .001C, in accordance with current interface standards. I would appreciate any feedback people can provide. Thanks.
