LPS0 constraints can be useful to other parts of the kernel to make
decisions what state to put devices into.

In v14 this series has been split into 3 parts.
 part A: Immediate fix for AMD issue.
 part B: LPS0 export improvements
 part C: Long term solution for all vendors

This is part B, it can be applied and reviewed independently from part A.

Andy Shevchenko (1):
  ACPI: x86: s2idle: Add for_each_lpi_constraint() helper

Mario Limonciello (6):
  ACPI: Adjust #ifdef for *_lps0_dev use
  ACPI: x86: s2idle: Post-increment variables when getting constraints
  ACPI: x86: s2idle: Catch multiple ACPI_TYPE_PACKAGE objects
  ACPI: x86: s2idle: Fix a logic error parsing AMD constraints table
  ACPI: x86: s2idle: Add more debugging for AMD constraints parsing
  ACPI: x86: s2idle: Add a function to get constraints for a device

All applied as 6.6 material, but I rewrote the last patch my way, so
please see the result in the bleeding-edge branch and let me know if
there's anything wrong with it.

Thanks!
