This adds probing for almost all recent (since 1999) ITE Super I/O chips to probe_superio. Not much of the configuration is dumped, however I did verify against all ITE datasheets (including those not available any more) that the probing was non-destructive. More information can be extracted easily, however this needs loads of datasheet surfing.

Tried on a pair of boards as requested.

With IT8712F-A:

Here is a bunch of superIO detected. Hope it helps,

Thanks, this is nice. However, it seems the following chunk disagrees with the datasheet:
name => "ITE IT8726F Super IO Sensors", driver => "it87", devid => 0x8726, logdev => 0x04,
According to the datasheet, devid for IT8726 is 0x8716.

Likely to be a typo in the datasheets, as they generally seem to follow the rule to make the ID identical to the actual Super I/O name, e.g. IT8712-F -> 0x8712 etc.
Of course you can only be sure if this is tested by someone who has a board with such a Super I/O...
Uwe.

Datasheet is wrong, the chip does return 0x8726

This adds probing for almost all recent (since 1999) ITE Super I/O chips to probe_superio. Not much of the configuration is dumped, however I did verify against all ITE datasheets (including those not available any more) that the probing was non-destructive.
