Subject: [PATCH 0/4] MFD: intel_pmt: Split OOBMSM from intel_pmt driver

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.

David E. Box (4):
  PCI: Add #defines for accessing PCIE DVSEC fields
  MFD: intel_pmt: Remove OOBMSM device for placement in own driver
  MFD: Add the Intel Out of Band Management Services Module (OOBMSM)
    driver
  MFD: intel-extended-cap: Add support for PCIe VSEC structures
