Thanks for the patch. I enhanced PWM support to the w83781d driver in late December, it is in CVS. I also attempted to standardize PWM support across all drivers. I also put in a userspace tool 'pwmtest', it is in prog/pwm. If you would give it a try I would appreciate it. Unfortunately CVS sensors requires CVS i2c and things are difficult to compile right now, we are making several changes. You may wish to wait a week or so. mds Uwe Bonnes wrote: > Hallo, > > appended patch exposes the switches in the W83781d.
