Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Use acpi_evaluate_dsm_typed() instead of open-coding _DSM
     evaluation to learn device characteristics (Andy Shevchenko)

   - Tidy multi-function header checks using new PCI_HEADER_TYPE_MASK
     definition (Ilpo Järvinen)

   - Simplify config access error checking in various drivers (Ilpo
     Järvinen)

   - Use pcie_capability_clear_word() (not
     pcie_capability_clear_and_set_word()) when only clearing (Ilpo
     Järvinen)

   - Add pci_get_base_class() to simplify finding devices using base
     class only (ignoring subclass and programming interface) (Sui
     Jingfeng)

   - Add pci_is_vga(), which includes ancient PCI_CLASS_NOT_DEFINED_VGA
     devices from before the Class Code was added to PCI (Sui Jingfeng)

   - Use pci_is_vga() for vgaarb, sysfs "boot_vga", virtio, qxl to
     include ancient VGA devices (Sui Jingfeng)

  Resource management:

   - Make pci_assign_unassigned_resources() non-init because sparc uses
     it after init (Randy Dunlap)

  Driver binding:

   - Retain .remove() and .probe() callbacks (previously __init) because
     sysfs may cause them to be called later (Uwe Kleine-König)

   - Prevent xHCI driver from claiming AMD VanGogh USB3 DRD device, so
     it can be claimed by dwc3 instead (Vicki Pfau)

  PCI device hotplug:

   - Add Ampere Altra Attention Indicator extension driver for acpiphp
     (D Scott Phillips)

  Power management:

   - Quirk VideoPropulsion Torrent QN16e with longer delay after reset
     (Lukas Wunner)

   - Prevent users from overriding drivers that say we shouldn't use
     D3cold (Lukas Wunner)

   - Avoid PME from D3hot/D3cold for AMD Rembrandt and Phoenix USB4
     because wakeup interrupts from those states don't work if amd-pmc
     has put the platform in a hardware sleep state (Mario Limonciello)

  IOMMU:

   - Disable ATS for Intel IPU E2000 devices with invalidation message
     endianness erratum (Bartosz Pawlowski)

  Error handling:

   - Factor out interrupt enable/disable into helpers (Kai-Heng Feng)

  Peer-to-peer DMA:

   - Fix flexible-array usage in struct pci_p2pdma_pagemap in case we
     ever use pagemaps with multiple entries (Gustavo A. R. Silva)

  ASPM:

   - Revert a change that broke when drivers disabled L1 and users later
     enabled an L1.x substate via sysfs, and fix a similar issue when
     users disabled L1 via sysfs (Heiner Kallweit)

  Endpoint framework:

   - Fix double free in __pci_epc_create() (Dan Carpenter)

   - Use IS_ERR_OR_NULL() to simplify endpoint core (Ruan Jinjie)

  Cadence PCIe controller driver:

   - Drop unused "is_rc" member (Li Chen)

  Freescale Layerscape PCIe controller driver:

   - Enable 64-bit addressing in endpoint mode (Guanhua Gao)

  Intel VMD host bridge driver:

   - Fix multi-function header check (Ilpo Järvinen)

  Microsoft Hyper-V host bridge driver:

   - Annotate struct hv_dr_state with __counted_by (Kees Cook)

  NVIDIA Tegra194 PCIe controller driver:

   - Drop setting of LNKCAP_MLW (max link width) since dw_pcie_setup()
     already does this via dw_pcie_link_set_max_link_width() (Yoshihiro
     Shimoda)

  Qualcomm PCIe controller driver:

   - Use PCIE_SPEED2MBS_ENC() to simplify encoding of link speed
     (Manivannan Sadhasivam)

   - Add a .write_dbi2() callback so DBI2 register writes, e.g., for
     setting the BAR size, work correctly (Manivannan Sadhasivam)

   - Enable ASPM for platforms that use 1.9.0 ops, because the PCI core
     doesn't enable ASPM states that haven't been enabled by the
     firmware (Manivannan Sadhasivam)

  Renesas R-Car Gen4 PCIe controller driver:

   - Add DesignWare core support (set max link width, EDMA_UNROLL flag,
     .pre_init(), .deinit(), etc) for use by R-Car Gen4 driver
     (Yoshihiro Shimoda)

   - Add driver and DT schema for DesignWare-based Renesas R-Car Gen4
     controller in both host and endpoint mode (Yoshihiro Shimoda)

  Xilinx NWL PCIe controller driver:

   - Update ECAM size to support 256 buses (Thippeswamy Havalige)

   - Stop setting bridge primary/secondary/subordinate bus numbers,
     since PCI core does this (Thippeswamy Havalige)

  Xilinx XDMA controller driver:

   - Add driver and DT schema for Zynq UltraScale+ MPSoCs devices with
     Xilinx XDMA Soft IP (Thippeswamy Havalige)

  Miscellaneous:

   - Use FIELD_GET()/FIELD_PREP() to simplify and reduce use of _SHIFT
     macros (Ilpo Järvinen, Bjorn Helgaas)

   - Remove logic_outb(), _outw(), outl() duplicate declarations (John
     Sanpe)

   - Replace unnecessary UTF-8 in Kconfig help text because menuconfig
     doesn't render it correctly (Liu Song)"
