Merge tag 'pci-v6.4-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
 "Resource management:

   - Add pci_dev_for_each_resource() and pci_bus_for_each_resource()
     iterators

  PCIe native device hotplug:

   - Fix AB-BA deadlock between reset_lock and device_lock

  Power management:

   - Wait longer for devices to become ready after resume (as we do for
     reset) to accommodate Intel Titan Ridge xHCI devices

   - Extend D3hot delay for NVIDIA HDA controllers to avoid
     unrecoverable devices after a bus reset

  Error handling:

   - Clear PCIe Device Status after EDR since generic error recovery now
     only clears it when AER is native

  ASPM:

   - Work around Chromebook firmware defect that clobbers Capability
     list (including ASPM L1 PM Substates Cap) when returning from
     D3cold to D0

  Freescale i.MX6 PCIe controller driver:

   - Install imprecise external abort handler only when DT indicates
     PCIe support

  Freescale Layerscape PCIe controller driver:

   - Add ls1028a endpoint mode support

  Qualcomm PCIe controller driver:

   - Add SM8550 DT binding and driver support

   - Add SDX55 DT binding and driver support

   - Use bulk APIs for clocks of IP 1.0.0, 2.3.2, 2.3.3

   - Use bulk APIs for reset of IP 2.1.0, 2.3.3, 2.4.0

   - Add DT "mhi" register region for supported SoCs

   - Expose link transition counts via debugfs to help debug low power
     issues

   - Support system suspend and resume; reduce interconnect bandwidth
     and turn off clock and PHY if there are no active devices

   - Enable async probe by default to reduce boot time

  Miscellaneous:

   - Sort controller Kconfig entries by vendor"
