[lm-sensors] [PATCH] Add f75375s driver

Sat Jul 7 19:26:06 CEST 2007

Hi Riku,

> Thanks for your time reviewing and testing the driver.
No problem. Without the driver i would't be able to manage the temperature/fan speed of my pc, so i have to thank you for your work.

OK, this was my fault if i set the value by hand i could also see the value using 'cat temp1_max_hyst' and sensors, i thought there would be an automatic entry i can read out.
What does this value exactly stand for, is it usefull for sensors or just a value i can read out using sensors?

Another problem i forget in my last mail. I don't know what's the reason, but if i do the following:
root at pc:/sys/devices/pci0000:00/0000:00:01.1/i2c-1/1-002d# cat fan1_min
i got following output:
<output>
root at pc:/sys/devices/pci0000:00/0000:00:01.1/i2c-1/1-002d# cat fan1_min

Maybe you can try to do the same on your machine, maybe the problem is related to my chip/pc?
