SVN rev 217286 on 2011-01-11 21:18:29Z by andreast
Add new functions, fcu_fan_set_pwm and fcu_fan_get_pwm, to set and get
the pwm values. We can now set the fan's speed of a PWM controlled fan
with % numbers between 30 and 100 % instead of trying to model a
% number based on rpm.
The fcu chip offers both, the dutycycle and the rpm value of the PWM
controlled fans. I added the rpm value to the list of information
available via sysctl(8).
