[v2,0/3] Uncore frequency scaling using TPMI

Message

Implement support of uncore frequency control via TPMI (Topology Aware
Register and PM Capsule Interface). This driver provides the similar
functionality as the current uncore frequency driver using MSRs.

Previously I posted only 1/3 and got reviewed and addressed with
this submission. The other two patches were links in the submission.

But it is better that all three patches considered together.
I know this is close to merge window for 6.4, so it is fine to differ.

Thank you for your patch-series, I've applied the series
(with the updated 1/3) to my review-hans branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
