Subject: Re: hwmon: xgene: Add support for X-Gene hwmon driver

Hi Hoan,

I didn't mention in my previous post, though I think I'm using fairly 
recent version of Tianocore F/W, and I can confirm there's the PCCT table,

[    0.000000] ACPI: PCCT 0x00000047FA826000 000300 (v01 APM    XGENE 
00000003      01000013)

is this still not enough? If that's the case, I'll talk to APM for
their latest development Tianocore version.
Also, if you or your folks can fold your patch set into APM's xgene-next
GitHub repo, that would help me to keep up with the development.

Itaru
