Bug Description
Feature: Correct uPEP support for all current ACPI _HID for AMD s2idle
Code:
Currently oem-5.10 carries hack ""platform/x86: force LPS0 functions for AMD"" which helps some RN platforms, but is not the correct solution.
The code that is the correct solution has been submitted to linux-acpi:
https://<email address hidden>/T/#t
This will fix RN properly and will also add support for the different variations used for CZN for uPEP.
Please replace hack in oem-5.10, and also apply this series for oem-5.13.
