Most of the devices in the intel_pmt driver are PMT only devices. However,
the Out of Band Management Services Module (OOBMSM) can also be used
access non-PMT devices. In order to better support this without the
confusion of a dependency on MFD_INTEL_PMT, this patch set rewrites the
intel_pmt driver to split the functionality into 3 components:
1. intel_pmt - driver for PMT only devices
2. intel-oobmsm - driver for devices using the OOBMSM IP which can
support multiple types of capabilities, including PMT
3. intel-extended-cap - symbols to handle adding platform device
for both drivers
Additionally, this patch set provides additional DVSEC macros in the PCI
header as well as support for reading capabilities from a VSEC structure.
Patch 1 - Adds PCI defines for DVSEC registers
Patch 2 - Removes OOBMSM from intel_pmt and creates intel-extended-cap.c
support the creation of platform devices for capabilities from
both intel_pmt and intel-oobmsm (Patch 3)
Patch 2 - Creates a separate driver for OOBMSM
Patch 3 - Adds support for reading capabilities from PCIe VSEC structures
For submission through MFD branch.
