[PATCH V3 0/6] Auxiliary bus driver support for Intel PCIe VSEC/DVSEC

This series makes changes to the current intel_pmt driver to give it
broader support for Intel defined PCIe VSEC and DVSEC features. It
moves the implementation from MFD to the auxiliary bus and creates a
generic framework for enumerating the extended capabilities. It also
adds support for a new VSEC, Software Defined Silicon (SDSi).

David E. Box (6):
PCI: Add #defines for accessing PCIe DVSEC fields
driver core: auxiliary bus: Add driver data helpers
platform/x86/intel: Move intel_pmt from MFD to Auxiliary Bus
platform/x86: Add Intel Software Defined Silicon driver
tools arch x86: Add Intel SDSi provisiong tool
selftests: sdsi: test sysfs setup
