[lm-sensors] Need some guidance on adhering to the sysfs
standards  George T. Joseph (development) gtj.devel at
peakin.com Thu Apr 12 18:50:30 CEST 2007  I'm wrapping up the
Andigilog driver and am having problems trying to adhere to the
sysfs auto_point definitions.  These chips have 2 temp points.
The low temp (auto_point1_temp) is simple enough to map to the
corresponding register.  The high point (auto_point2_temp) isn't
so easy because it's implemented as a range with the low temp as
a base.  Even worse, range is not an arbitrary value; it's a
value from a list of 16.  So if a user chooses 26 for a low
point and 50 for a high point, that's a range of 24 except that
24 isn't a valid range value.  The closest values are either 20
or 26.67. Also, if the user sets the high point then changes the
low point, the high point will probably have to be changed
because the new calculated range might not be a valid value.
Auto_point_pwm is also an issue.  Where there are 4 temp zones,
there are only 3 pwm outputs a
