  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.

Just a heads-up that this pull request doesn't include the following
topic branches in pci.git:

    controller/endpoint
    controller/cadence
    controller/vmd

... as well as the following commit on the controller/dt branch:

    661a7e9aa551 ("dt-bindings: PCI: qcom: Add SDX65 SoC")

Perhaps you intend to submit them in a second pull request this
merge window, but I just wanted to make sure they're not forgotten.
The patches applied to those topic branches are marked "Accepted"
in patchwork, so if the topic branches are deleted when the 6.5
cycle begins, the patches would seem to have been merged even though
they're not.

Thanks,

Lukas

Yeah, thanks, this was unfortunate timing.  I did the last updates for
the v6.4 pull request on Apr 20, left for a long weekend, and Lorenzo
merged the branches you mentioned on Apr 21.

If they were critical, maybe a second pull request could work, but I
don't plan on that because they haven't had any time in -next yet.

I'll try not to delete them before v6.5; here are the heads in case I
forget:

  eac223e85208 remotes/pci/controller/cadence
  661a7e9aa551 remotes/pci/controller/dt
  604de32d55a2 remotes/pci/controller/endpoint
  e06720c1d9e1 remotes/pci/controller/vmd

I rebased these branches on top of v6.4-rc1 and pushed them out.

Thanks,
