Hi Boris,

thanks for your best wishes in the last mail, I'm feeling little better now.

The new step_wise thermal governor wasn't able to handle the one-trip
point design of acerhdf where we want to turn off the fan if we go under
the 'fanoff' temperature and to turn it on only after exceeding the
'fanon' temperature.

Do that by looking at the current fan state and return the temperature

Ok, ignore this one for now - the suspend/resume path doesn't pan out
somehow, need to do some more handholding here.

Please test my last patch with the 4 trip points ;) - even if you don't really like it, it is working great! - And to be honest, I still prefer this solution!

Anyhow, did you test what Rui asked us to test?

kind regards,
