+         This driver discovers PMC SSRAM telemetry regions through the PMC's
+         MMIO interface (PCI) or ACPI _DSD properties and registers them with
+         the Intel VSEC framework as Intel PMT telemetry devices.
+
+         It probes the PMC SSRAM device, extracts DVSEC information from MMIO,
+         reads device IDs and base addresses for multiple PMCs (main, IOE, PCH),
+         and exposes the discovered telemetry through Intel PMT interfaces
+         (including sysfs).
+
+         This option is selected by INTEL_PMC_CORE.
