+	help
+	  This PCI driver discovers PMC SSRAM telemetry regions through the
+	  PMC's MMIO interface 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.
