Merge tag 'pci-v6.3-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Rework portdrv shutdown so it disables interrupts but doesn't
     disable bus mastering, which leads to hangs on Loongson LS7A

   - Add mechanism to prevent Max_Read_Request_Size (MRRS) increases,
     again to avoid hardware issues on Loongson LS7A (and likely other
     devices based on DesignWare IP)

   - Ignore devices with a firmware (DT or ACPI) node that says the
     device is disabled

  Resource management:

   - Distribute spare resources to unconfigured hotplug bridges at
     boot-time (not just when hot-adding such a bridge), which makes
     hot-adding devices to docks work better. Tried this in v6.1 but had
     to revert for regressions, so try again

   - Fix root bus issue that dropped resources that happened to end
     at 0, e.g., [bus 00]

  PCI device hotplug:

   - Remove device locking when marking device as disconnected so this
     doesn't have to wait for concurrent driver bind/unbind to complete

   - Quirk more Qualcomm bridges that don't fully implement the PCIe
     Slot Status 'Command Completed' bit

  Power management:

   - Account for _S0W of the target bridge in acpi_pci_bridge_d3() so we
     don't miss hot-add notifications for USB4 docks, Thunderbolt, etc

  Reset:

   - Observe delay after reset, e.g., resuming from system sleep,
     regardless of whether a bridge can suspend to D3cold at runtime

   - Wait for secondary bus to become ready after a bridge reset

  Virtualization:

   - Avoid FLR on some AMD FCH AHCI adapters where it doesn't work

   - Allow independent IOMMU groups for some Wangxun NICs that prevent
     peer-to-peer transactions but don't advertise an ACS Capability

  Error handling:

   - Configure End-to-End-CRC (ECRC) only if Linux owns the AER
     Capability

   - Remove redundant Device Control Error Reporting Enable in the AER
     service driver since this is already done for all devices during
     enumeration

  ASPM:

   - Add pci_enable_link_state() interface to allow drivers to enable
     ASPM link state

  Endpoint framework:

   - Move dra7xx and tegra194 linkup processing from hard IRQ to
     threaded IRQ handler

   - Add a separate lock for endpoint controller list of endpoint
     function drivers to prevent deadlock in callbacks

   - Pass events from endpoint controller to endpoint function drivers
     via callbacks instead of notifiers

  Synopsys DesignWare eDMA controller driver (acked by Vinod):

   - Fix CPU vs PCI address issues

   - Fix source vs destination address issues

   - Fix issues with interleaved transfer semantics

   - Fix channel count initialization issue (issue still exists in
     several other drivers)

   - Clean up and improve debugfs usage so it will work on platforms
     with several eDMA devices

  Baikal T-1 PCIe controller driver:

   - Set a 64-bit DMA mask

  Freescale i.MX6 PCIe controller driver:

   - Add i.MX8MM, i.MX8MQ, i.MX8MP endpoint mode DT binding and driver
     support

  Intel VMD host bridge driver:

   - Add quirk to configure PCIe ASPM and LTR. This is normally done by
     BIOS, and will be for future products

  Marvell MVEBU PCIe controller driver:

   - Mark this driver as broken in Kconfig since bugs prevent its daily
     usage

  MediaTek MT7621 PCIe controller driver:

   - Delay PHY port initialization to improve boot reliability for ZBT
     WE1326, ZBT WF3526-P, and some Netgear models

  Qualcomm PCIe controller driver:

   - Add MSM8998 DT compatible string

   - Unify MSM8996 and MSM8998 clock orderings

   - Add SM8350 DT binding and driver support

   - Add IPQ8074 Gen3 DT binding and driver support

   - Correct qcom,perst-regs in DT binding

   - Add qcom_pcie_host_deinit() so the PHY is powered off and
     regulators and clocks are disabled on late host-init errors

  Socionext UniPhier Pro5 controller driver:

   - Clean up uniphier-ep reg, clocks, resets, and their names in DT
     binding

  Synopsys DesignWare PCIe controller driver:

   - Restrict coherent DMA mask to 32 bits for MSI, but allow controller
     drivers to set 64-bit streaming DMA mask

   - Add eDMA engine support in both Root Port and Endpoint controllers

  Miscellaneous:

   - Remove MODULE_LICENSE from boolean drivers so they don't look like
     modules so modprobe can complain about them"
