Subject: [PATCH v1 0/5] Enable SSRAM support in PTL and LNL

This series enables SSRAM support, including achieving PMC information
and low power mode substate requirements from telemetry region, in Lunar
Lake and Panther Lake platforms for Intel PMC Core driver. 

The first patch enables SSRAM support for Lunar Lake. The next three
patches introduces a new table in telemetry region to get substate
requirement information for platforms starting from Panther Lake. The
last patch enables SSRAM support for Panther Lake.

Xi Pardee (5):
  platform/x86:intel/pmc: Enable SSRAM support for Lunar Lake
  platform/x86:intel/pmc: Move telemetry endpoint register handling
  platform/x86:intel/pmc: Improve function to show substate header
  platform/x86:intel/pmc: Show substate requirement for S0ix blockers
  platform/x86:intel/pmc: Enable SSRAM support for Panther Lake
