Merge branch 'pci/controller/kconfig' (2023-04-20 16:19:37 -0500)

You should see a trivial conflict between f195fc1e9715 ("x86/PCI: Add quirk
for AMD XHCI controller that loses MSI-X state in D3hot"), which you
already have, and 606012dddebb ("PCI: Fix up L1SS capability for Intel
Apollo Lake Root Port"), which is included here.

----------------------------------------------------------------

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.
