David E. Box 104f74943f platform/x86/intel/pmc: Find and register PMC telemetry entries 
The PMC SSRAM device contains counters that are structured in Intel
Platform Monitoring Technology (PMT) telemetry regions. Look for and
register these telemetry regions from the driver so that they may be read
using the Intel PMT ABI.

Intel x86 Platform-Specific Drivers

config INTEL_PMC_CORE tristate "Intel PMC Core driver" depends on PCI depends on ACPI depends on INTEL_PMT_TELEMETRY help The Intel Platform Controller Hub for Intel Core SoCs provides access to Power Management Controller registers via various interfaces. This driver can utilize debugging capabilities and supported features as exposed by the Power Management Controller. It also may perform some tasks in the PMC in order to enable transition into the SLPS0 state. It should be selected on all Intel platforms supported by the driver.

  Supported features:
	- SLP_S0_RESIDENCY counter
	- PCH IP Power Gating status
	- LTR Ignore / LTR Show
	- MPHY/PLL gating status (Sunrisepoint PCH only)
	- SLPS0 Debug registers (Cannonlake/Icelake PCH)
	- Low Power Mode registers (Tigerlake and beyond)
	- PMC quirks as needed to enable SLPS0/S0ix
