Add support for the IT8732F. This chip is pretty similar to IT8721F,
with the main difference being that the ADC LSB is 10.9 mV instead of
12 mV.
I assume you have a datasheet. Since you say "main difference",
are you aware of any other differences ? Would it by any chance
be possible to share the datasheet with us ?
Yes, I do have a datasheet. I'm investigating our confidentiality
obligations now, but I'm unsure what that outcome will be. I don't
Ok.
have datasheets for any other chips, so I can't really do a proper
comparison. But the driver code for IT8721F seems to line up well
with the IT8732F datasheet.
IT8732F has up to 4 fan tachometer inputs, and up to 4 PWM outputs.
The "SmartGuardian" piece appears identical. As I mentioned in the
doc change, it also has a fan tachometer closed-loop mode that seems
new (at least I didn't see any reference to it in the driver). That
IT8772F supports it as well. Datasheet isn't published, but you might be
able to find leaked versions on the web. Search for IT8772_F_V0.4_031612.
