Subject: [PATCH 00/11] Intel pmc_core: Enable telemetry

On Intel SoCs, registers for the Power Management Controller are available
in the PCI BAR of the SSRAM device, 0000:14.2. On Meteor Lake, these
registers are structured in Intel PMT Telemetry regions which could be
handled by the pmt_telemetry driver. This series adds APIs to the
intel_vsec and pmt_telemetry drivers so that pmc_core driver can both
create the telemetry instance from the SSRAM device and register for a
handle to read the telemetry which contains the low power mode requirements
for the S0ix states supported by Meteor Lake. The series also adds some
fixes.

David E. Box (6):
  platform/x86/intel/vsec: Explicitly enable capabilities
  platform/x86/intel/vsec: Add base address field
  platform/x86/intel/pmt: Add INTEL_PMT module namespace
  platform/x86/intel/pmt: telemetry: Add telemetry read functions
  platform/x86/intel/pmt/telemetry: Add driver version
  platform/x86/intel/pmc: Add Intel PMT support for MTL PMC

Gayatri Kammela (1):
  platform/x86/intel/vsec: Add intel_vsec_register

Rajvi Jingar (1):
  platform/x86/intel/pmc: Alder Lake slp_s0_residency fix

Xi Pardee (3):
  platform/x86:intel/pmc: Combine core_init and core_configure function
  platform/x86:intel/pmc: Move get_low_power_modes function
  platform/x86/intel/pmc/mtl: get LPM information using Intel PMT
