Fix my misinterpretation of the datasheet. Really? I'm confused. The ADT7470 has 4 PWM outputs and 10 temperature inputs. There are only 4 Tmin registers. How can they be attached to temperature inputs? What about inputs temp5 to temp10? I think your original interpretation is correct and Tmin is attached to a PWM channel, and this patch is incorrect.
