[lm-sensors] [PATCH 2.6.25.4] f71882.c driver, Added PWM/FAN control.

[Mark van Doesburg]

Hello Hans,

Your proposal sounds fine to me. I wasn't too happy with the fan?_target
pwm? conflict either.  So I will implement the following:

	1. Remove fan?_target.
	2. Add fan?_full_speed.
	3. Interpret pwm? as the duty cycle when in duty cycle mode.
	4. Scale pwm? from 0..255 to 0..fan?_full_speed when in rpm mode.
	5. Change the behavior of pwm?_enable not to change pwm vs. duty
	   cycle mode.
	5. Add module option to select rpm/duty cycle mode.  
	6. Add pwm?_auto*

This will take some time of course. (Although being able to read the
temperature of my "Asus EAH3650 silent" would speed things up ;-)

My BIOS doesn't put a usefull value in the full speed register. There is
also no way to set the case fan to anything but a fixed PWM value. Then
again I build the computer from seperate components, I can imagine a
fully assembled system could do more.

regards,

Mark van Doesburg.
