64 Fan readings are affected by a programmable clock divider, giving the
65 readings more range or accuracy. Usually, users have to learn how it works,
66 but this driver implements dynamic clock divider selection, so you don't
69 For reference, here are a few values about clock dividers:
71 slowest accuracy highest
80 * slowest measurable speed: clock/(255*divider)
81 * accuracy around 3000 RPM: 3000^2/clock
82 * highest accurate speed: sqrt(clock*100)
83 The clock speed for the PC87360 family is 480 kHz. I arbitrarily chose 100
84 RPM as the lowest acceptable accuracy.
88 Note that not all RPM values can be represented, even when the best clock
