Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Revert sysfs "rescan" renames that broke apps (Kelsey Skunberg)

   - Add more 32 GT/s link speed decoding and improve the implementation
     (Yicong Yang)

  Resource management:

   - Add support for sizing programmable host bridge apertures and fix a
     related alpha Nautilus regression (Ivan Kokshaysky)

  Interrupts:

   - Add boot interrupt quirk mechanism for Xeon chipsets and document
     boot interrupts (Sean V Kelley)

  PCIe native device hotplug:

   - When possible, disable in-band presence detect and use PDS
     (Alexandru Gagniuc)

   - Add DMI table for devices that don't use in-band presence detection
     but don't advertise that correctly (Stuart Hayes)

   - Fix hang when powering slots up/down via sysfs (Lukas Wunner)

   - Fix an MSI interrupt race (Stuart Hayes)

  Virtualization:

   - Add ACS quirks for Zhaoxin devices (Raymond Pang)

  Error handling:

   - Add Error Disconnect Recover (EDR) support so firmware can report
     devices disconnected via DPC and we can try to recover (Kuppuswamy
     Sathyanarayanan)

  Peer-to-peer DMA:

   - Add Intel Sky Lake-E Root Ports B, C, D to the whitelist (Andrew
     Maier)

  ASPM:

   - Reduce severity of common clock config message (Chris Packham)

   - Clear the correct bits when enabling L1 substates, so we don't go
     to the wrong state (Yicong Yang)

  Endpoint framework:

   - Replace EPF linkup ops with notifier call chain and improve locking
     (Kishon Vijay Abraham I)

   - Fix concurrent memory allocation in OB address region (Kishon Vijay
     Abraham I)

     function creation methods (Kishon Vijay Abraham I)

   - Fix issue with clearing configfs "start" entry (Kunihiko Hayashi)

   - Fix issue with endpoint MSI-X ignoring BAR Indicator and Table
     Offset (Kishon Vijay Abraham I)

   - Add support for testing DMA transfers (Kishon Vijay Abraham I)

   - Add support for tests to clear IRQ (Kishon Vijay Abraham I)

   - Add common DT schema for endpoint controllers (Kishon Vijay Abraham I)

  Amlogic Meson PCIe controller driver:

   - Add DT bindings for AXG PCIe PHY, shared MIPI/PCIe analog PHY (Remi
     Pommarel)

     Kalakota)

  Mobiveil PCIe controller driver:

   - Refactor and modularize mobiveil driver (Hou Zhiqiang)

     PCI_BUS_RELATIONS2 (Long Li)

   - Refactor to prepare for virtual PCI on non-x86 architectures (Boqun
     Feng)

   - Fix memory leak in hv_pci_probe()'s error path (Dexuan Cui)

   - Use pci_parse_request_of_pci_ranges() (Rob Herring)

   - Add support for endpoint mode and related DT updates (Vidya Sagar)

   - Reduce -EPROBE_DEFER error message log level (Thierry Reding)

  Qualcomm PCIe controller driver:

   - Restrict class fixup to specific Qualcomm devices (Bjorn Andersson)

  Synopsys DesignWare PCIe controller driver:

   - Refactor core initialization code for endpoint mode (Vidya Sagar)

   - Fix endpoint MSI-X to use correct table address (Kishon Vijay
     Abraham I)

  TI DRA7xx PCIe controller driver:

   - Fix MSI IRQ handling (Vignesh Raghavendra)

  TI Keystone PCIe controller driver:

   - Allow AM654 endpoint to raise MSI-X interrupt (Kishon Vijay Abraham I)

  Miscellaneous:

   - Quirk ASMedia XHCI USB to avoid "PME# from D0" defect (Kai-Heng
     Feng)

   - Use ioremap(), not phys_to_virt(), for platform ROM to fix video
     ROM mapping with CONFIG_HIGHMEM (Mikel Rychliski)"
