+ 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.
