This series updates intel_vsec to improve const-correctness, decouple
helper APIs from PCI, enhance error handling, and plumb ACPI-based Intel
Platform Monitoring Technology (PMT) discovery through the vsec layer. It
is preparatory infrastructure for follow-on PMT core/telemetry and
PMC/SSRAM series that add ACPI discovery and support for new platforms.
The series is organized as follows:
Patches 1-2 refactor and improve const-correctness of base_addr handling.
Patch 1 makes base_addr an explicit parameter throughout the call chain,
clarifying ownership and removing conditional logic. Patch 2 then makes the
platform info data structure read-only, preventing unintended modifications
to shared driver data.
Patches 3-4 decouple the vsec layer from PCI-specific types, updating
helper APIs and data structures to use generic struct device instead of
struct pci_dev. This enables vsec to work with both PCI and ACPI parent
devices.
Patch 5 enhances error visibility by returning meaningful error codes from
the registration path instead of collapsing to boolean success/failure.
Patch 6 adds infrastructure for ACPI-based PMT discovery, allowing client
drivers to consume discovery data from either PCI or ACPI sources.
