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.
