[lm-sensors] IT8620E/IT8623E vs. IT8603E

[lm-sensors] IT8620E/IT8623E vs. IT8603E

[Jean Delvare]

Hi Rudolf,

Recently you added support for the IT8603E chip to the it87 driver.
Since then we had a number of requests to support the IT8620E and the
IT8623E as well, for which we do not have a datasheet.

Do you happen to know if there is some degree of compatibility between
these 3 chips?

Thanks,

No idea, but I guess they are quite similar. Maybe we can check regs 58h and 5bh 
in HWM block. It should be 90h and 12h.

I will try to contact the Asus and we will see.

Thanks
Rudolf

Hi Jean,

The IT8623E is same asi IT8603E. Asus has no information about IT8620E.

Do you have any testers for IT8603E?

Thanks
Rudolf

Hi Jean

According to 
http://lists.lm-sensors.org/pipermail/lm-sensors/2013-August/039551.html

Trying family `ITE'...                                      Yes
Found unknown chip with ID 0x8623
      (logical device 4 has address 0x290, could be sensors)

It has the ID of it8623. Will you have a time to prepare the patch or should I?

Thanks
Rudolf

I will take care of sensors-detect and the wiki, and would appreciate
if you could write the patch for the it87 driver.

Hi all,

I developed the patch and I need a test from the Martin. In fact I found small 
typo (no code impact) which I will fix in the first patch, second patch just 
adds documentation and it87 will treat the IT8623E as it would be IT8603E 
similar way as we do for 8716/26 pair.

I will start new thread with my patches.

Thanks
Rudolf

For the record: the IT8620E turns out to be a custom chipset made by
ITE for Gigabyte, so it is no surprise that Asus had no information
about it. It also explains why the part number doesn't show up on ITE's
website.

Do we know enough about the chip to add support for it ?

I have a patch adding experimental support for it, but of course
there is a lot of guesswork involved.

Is this still an open issue that needs testing? I have a gigabyte mainboard
with the IT8620E and am very willing to test this if it is helpful.

Cheers
Sebastian

Hi Sebastian,

Additional tests results are always welcome. Please try the driver at
https://github.com/groeck/it87.

Thanks,
Guenter
