[lm-sensors] Looking for IT8720 datasheet.

Hi Jean,

Thanks for your reply.

Hi Frank,

Did you get a chance to work on IT8720? I have modify the
sensors-detect script to return it87, and also modify it87.c to handle
the IT8720 as any other IT87 chipset, and it seems to work pretty
fine. It's fine for the FANs and the temp, but I'm not 100% sur for
the voltage.

in0:         +0.00 V  (min =  +0.00 V, max =  +4.08 V)   ALARM
in1:         +3.02 V  (min =  +0.00 V, max =  +4.08 V)
in2:         +3.42 V  (min =  +0.00 V, max =  +4.08 V)
in3:         +3.01 V  (min =  +0.00 V, max =  +4.08 V)
in4:         +1.22 V  (min =  +0.00 V, max =  +4.08 V)
in5:         +2.62 V  (min =  +0.00 V, max =  +4.08 V)
in6:         +2.59 V  (min =  +0.00 V, max =  +4.08 V)
in7:         +3.01 V  (min =  +0.00 V, max =  +4.08 V)
in8:         +3.38 V

I didn't get the +12 or -5 or others. I was able to get it one time,
and no more. Any idea?
