Dear lm-sensors team,

Thank you for all the hard work to support devices. I own Shuttle SH67H3,
which is IT8772F chipset.
Following instructions for a similar chipset, I've tried modprobe it87
force_id=0x8721
Here is what I've got

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +42.0°C  (high = +80.0°C, crit = +98.0°C)
Core 0:         +40.0°C  (high = +80.0°C, crit = +98.0°C)
Core 1:         +39.0°C  (high = +80.0°C, crit = +98.0°C)
Core 2:         +39.0°C  (high = +80.0°C, crit = +98.0°C)
Core 3:         +40.0°C  (high = +80.0°C, crit = +98.0°C)

it8721-isa-0a30
Adapter: ISA adapter
in0:          +0.98 V  (min =  +0.25 V, max =  +0.96 V)  ALARM
in1:          +1.56 V  (min =  +2.71 V, max =  +0.19 V)  ALARM
in2:          +1.07 V  (min =  +0.29 V, max =  +1.40 V)
in3:          +1.06 V  (min =  +1.04 V, max =  +0.00 V)  ALARM
in4:          +1.02 V  (min =  +0.91 V, max =  +1.64 V)
in5:          +2.23 V  (min =  +1.84 V, max =  +0.83 V)  ALARM
in6:          +2.23 V  (min =  +1.03 V, max =  +1.32 V)  ALARM
3VSB:         +3.29 V  (min =  +1.63 V, max =  +1.78 V)  ALARM
Vbat:         +3.24 V
fan1:           0 RPM  (min =  958 RPM)  ALARM
fan2:        1090 RPM  (min =   18 RPM)
fan3:           0 RPM  (min =   19 RPM)  ALARM
temp1:        +40.0°C  (low  = +64.0°C, high = -79.0°C)  ALARM  sensor =
thermistor
temp2:        +44.0°C  (low  = -36.0°C, high = -124.0°C)  sensor = thermal
diode
temp3:       -128.0°C  (low  =  +4.0°C, high = +33.0°C)  sensor = disabled

Note that Shuttle has only one fan built in, so fan speed readings are
probably right. For all other weird readings, I get those from SpeedFan,
too.
I was able to do pwmconfig to make fan2 correlate to temp2, and it seems to
be working fine.

Kind regards,
In-Ho Yi

Probably quite compatible, but there are a few quirks with the 8772 for which I'd rather
see a datasheet.

On the plus side, looks like Open Hardware Monitor and Mosys (Google) support it, so
maybe there is enough information available to make it work. We'll have to see.
