[lm-sensors] ITE IT8721F chipset support? [typo]

[lm-sensors] ITE IT8721F chipset support? [typo]

[Jelle de Jong]

Hello everybody,

[I made a confusing typo; IT8712F instead of IT8721F]

I got a new motherboard with an ITE IT8721F and it seems there is no
driver support yet. I tested with the latest sensors-detect and
checked the 2.6.34 kernel code.

http://debian.pastebin.com/P50Mf0Bv # latest sensors-detect

I want to use the driver to control fans with PWM. There are two four
pin fan connectors on the motherboard and the BIOS shows support for
PWM fans in silent standard turbo and manual mode.

I can't find a datasheet with the differences between 20f and 21f? If
somebody can add support for this chipset I would be very thankful.

I helped in the past with providing motherboards for developers. I can
also provide remote SSH root access to this system if needed.

Thank in advance,

With kind regards,

Jelle de Jong

New chip. I've added detection to sensors-detect, but we have no
support yet. The chip isn't even listed on ITE's website.

Asus board. You will have to use the asus_atk0110 driver.

Manual fan speed control isn't available on Asus desktop boards that
implement ATK0110, and probably never will. I fear you chose the wrong
board for the job, sorry.
