Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Skip E820 checks for MCFG ECAM regions for new (2016+) machines,
     since there's no requirement to describe them in E820 and some
     platforms require ECAM to work (Bjorn Helgaas)

   - Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more specific (Damien
     Le Moal)

   - Remove last user and pci_enable_device_io() (Heiner Kallweit)

   - Wait for Link Training==0 to avoid possible race (Ilpo Järvinen)

   - Skip waiting for devices that have been disconnected while
     suspended (Ilpo Järvinen)

   - Clear Secondary Status errors after enumeration since Master Aborts
     and Unsupported Request errors are an expected part of enumeration
     (Vidya Sagar)

  MSI:

   - Remove unused IMS (Interrupt Message Store) support (Bjorn Helgaas)

  Error handling:

   - Mask Genesys GL975x SD host controller Replay Timer Timeout
     correctable errors caused by a hardware defect; the errors cause
     interrupts that prevent system suspend (Kai-Heng Feng)

   - Fix EDR-related _DSM support, which previously evaluated revision 5
     but assumed revision 6 behavior (Kuppuswamy Sathyanarayanan)

  ASPM:

   - Simplify link state definitions and mask calculation (Ilpo
     Järvinen)

  Power management:

   - Avoid D3cold for HP Pavilion 17 PC/1972 PCIe Ports, where BIOS
     apparently doesn't know how to put them back in D0 (Mario
     Limonciello)

  CXL:

   - Support resetting CXL devices; special handling required because
     CXL Ports mask Secondary Bus Reset by default (Dave Jiang)

  DOE:

   - Support DOE Discovery Version 2 (Alexey Kardashevskiy)

  Endpoint framework:

   - Set endpoint BAR to be 64-bit if the driver says that's all the
     device supports, in addition to doing so if the size is >2GB
     (Niklas Cassel)

   - Simplify endpoint BAR allocation and setting interfaces (Niklas
     Cassel)

  Cadence PCIe controller driver:

   - Drop DT binding redundant msi-parent and pci-bus.yaml (Krzysztof
     Kozlowski)

  Cadence PCIe endpoint driver:

   - Configure endpoint BARs to be 64-bit based on the BAR type, not the
     BAR value (Niklas Cassel)

  Freescale Layerscape PCIe controller driver:

   - Convert DT binding to YAML (Frank Li)

  MediaTek MT7621 PCIe controller driver:

   - Add DT binding missing 'reg' property for child Root Ports
     (Krzysztof Kozlowski)

   - Fix theoretical string truncation in PHY name (Sergio Paracuellos)

  NVIDIA Tegra194 PCIe controller driver:

   - Return success for endpoint probe instead of falling through to the
     failure path (Vidya Sagar)

  Renesas R-Car PCIe controller driver:

   - Add DT binding missing IOMMU properties (Geert Uytterhoeven)

   - Add DT binding R-Car V4H compatible for host and endpoint mode
     (Yoshihiro Shimoda)

  Rockchip PCIe controller driver:

   - Configure endpoint BARs to be 64-bit based on the BAR type, not the
     BAR value (Niklas Cassel)

   - Add DT binding missing maxItems to ep-gpios (Krzysztof Kozlowski)

   - Set the Subsystem Vendor ID, which was previously zero because it
     was masked incorrectly (Rick Wertenbroek)

  Synopsys DesignWare PCIe controller driver:

   - Restructure DBI register access to accommodate devices where this
     requires Refclk to be active (Manivannan Sadhasivam)

   - Remove the deinit() callback, which was only need by the
     pcie-rcar-gen4, and do it directly in that driver (Manivannan
     Sadhasivam)

   - Add dw_pcie_ep_cleanup() so drivers that support PERST# can clean
     up things like eDMA (Manivannan Sadhasivam)

   - Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit() to make it parallel
     to dw_pcie_ep_init() (Manivannan Sadhasivam)

   - Rename dw_pcie_ep_init_complete() to dw_pcie_ep_init_registers() to
     reflect the actual functionality (Manivannan Sadhasivam)

   - Call dw_pcie_ep_init_registers() directly from all the glue
     drivers, not just those that require active Refclk from the host
     (Manivannan Sadhasivam)

   - Remove the "core_init_notifier" flag, which was an obscure way for
     glue drivers to indicate that they depend on Refclk from the host
     (Manivannan Sadhasivam)

  TI J721E PCIe driver:

   - Add DT binding J784S4 SoC Device ID (Siddharth Vadapalli)

   - Add DT binding J722S SoC support (Siddharth Vadapalli)

  TI Keystone PCIe controller driver:

   - Add DT binding missing num-viewport, phys and phy-name properties
     (Jan Kiszka)

  Miscellaneous:

   - Constify and annotate with __ro_after_init (Heiner Kallweit)

   - Convert DT bindings to YAML (Krzysztof Kozlowski)

   - Check for kcalloc() failure in of_pci_prop_intr_map() (Duoming
     Zhou)"
