Merge tag 'pci-v6.17-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
"Enumeration:

- Allow built-in drivers, not just modular drivers, to use async
initial probing (Lukas Wunner)

- Support Immediate Readiness even on devices with no PM Capability
(Sean Christopherson)

- Consolidate definition of PCIE_RESET_CONFIG_WAIT_MS (100ms), the
required delay between a reset and sending config requests to a
device (Niklas Cassel)

- Add pci_is_display() to check for "Display" base class and use it
in ALSA hda, vfio, vga_switcheroo, vt-d (Mario Limonciello)

- Allow 'isolated PCI functions' (multi-function devices without a
function 0) for LoongArch, similar to s390 and jailhouse (Huacai
Chen)

Power control:

- Add ability to enable optional slot clock for cases where the PCIe
host controller and the slot are supplied by different clocks
(Marek Vasut)

PCIe native device hotplug:

- Fix runtime PM ref imbalance on Hot-Plug Capable ports caused by
misinterpreting a config read failure after a device has been
removed (Lukas Wunner)

- Avoid creating a useless PCIe port service device for pciehp if the
slot is handled by the ACPI hotplug driver (Lukas Wunner)

- Ignore ACPI hotplug slots when calculating depth of pciehp hotplug
ports (Lukas Wunner)

Virtualization:

- Save VF resizable BAR state and restore it after reset (Michał
Winiarski)

- Allow IOV resources (VF BARs) to be resized (Michał Winiarski)

- Add pci_iov_vf_bar_set_size() so drivers can control VF BAR size
(Michał Winiarski)

Endpoint framework:

- Add RC-to-EP doorbell support using platform MSI controller,
including a test case (Frank Li)

- Allow BAR assignment via configfs so platforms have flexibility in
determining BAR usage (Jerome Brunet)

Native PCIe controller drivers:

- Convert amazon,al-alpine-v[23]-pcie, apm,xgene-pcie,
axis,artpec6-pcie, marvell,armada-3700-pcie, st,spear1340-pcie to
DT schema format (Rob Herring)

- Use dev_fwnode() instead of of_fwnode_handle() to remove OF
dependency in altera (fixes an unused variable), designware-host,
mediatek, mediatek-gen3, mobiveil, plda, xilinx, xilinx-dma,
xilinx-nwl (Jiri Slaby, Arnd Bergmann)

- Convert aardvark, altera, brcmstb, designware-host, iproc,
mediatek, mediatek-gen3, mobiveil, plda, rcar-host, vmd, xilinx,
xilinx-dma, xilinx-nwl from using pci_msi_create_irq_domain() to
using msi_create_parent_irq_domain() instead; this makes the
interrupt controller per-PCI device, allows dynamic allocation of
vectors after initialization, and allows support of IMS (Nam Cao)

APM X-Gene PCIe controller driver:

- Rewrite MSI handling to MSI CPU affinity, drop useless CPU hotplug
bits, use device-managed memory allocations, and clean things up
(Marc Zyngier)

- Probe xgene-msi as a standard platform driver rather than a
subsys_initcall (Marc Zyngier)

Broadcom STB PCIe controller driver:

- Add optional DT 'num-lanes' property and if present, use it to
override the Maximum Link Width advertised in Link Capabilities
(Jim Quinlan)

Cadence PCIe controller driver:

- Use PCIe Message routing types from the PCI core rather than
defining private ones (Hans Zhang)

Freescale i.MX6 PCIe controller driver:

- Add IMX8MQ_EP third 64-bit BAR in epc_features (Richard Zhu)

- Add IMX8MM_EP and IMX8MP_EP fixed 256-byte BAR 4 in epc_features
(Richard Zhu)

- Configure LUT for MSI/IOMMU in Endpoint mode so Root Complex can
trigger doorbel on Endpoint (Frank Li)

- Remove apps_reset (LTSSM_EN) from
imx_pcie_{assert,deassert}_core_reset(), which fixes a hotplug
regression on i.MX8MM (Richard Zhu)

- Delay Endpoint link start until configfs 'start' written (Richard
Zhu)

Intel VMD host bridge driver:

- Add Intel Panther Lake (PTL)-H/P/U Vendor ID (George D Sworo)

Qualcomm PCIe controller driver:

- Add DT binding and driver support for SA8255p, which supports ECAM
for Configuration Space access (Mayank Rana)

- Update DT binding and driver to describe PHYs and per-Root Port
resets in a Root Port stanza and deprecate describing them in the
host bridge; this makes it possible to support multiple Root Ports
in the future (Krishna Chaitanya Chundru)

- Add Qualcomm QCS615 to SM8150 DT binding (Ziyue Zhang)

- Add Qualcomm QCS8300 to SA8775p DT binding (Ziyue Zhang)

- Drop TBU and ref clocks from Qualcomm SM8150 and SC8180x DT
bindings (Konrad Dybcio)

- Document 'link_down' reset in Qualcomm SA8775P DT binding (Ziyue
Zhang)

- Add required PCIE_RESET_CONFIG_WAIT_MS delay after Link up IRQ
(Niklas Cassel)

Rockchip PCIe controller driver:

- Drop unused PCIe Message routing and code definitions (Hans Zhang)

- Remove several unused header includes (Hans Zhang)

- Use standard PCIe config register definitions instead of
rockchip-specific redefinitions (Geraldo Nascimento)

- Set Target Link Speed to 5.0 GT/s before retraining so we have a
chance to train at a higher speed (Geraldo Nascimento)

Rockchip DesignWare PCIe controller driver:

- Prevent race between link training and register update via DBI by
inhibiting link training after hot reset and link down (Wilfred
Mallawa)

- Add required PCIE_RESET_CONFIG_WAIT_MS delay after Link up IRQ
(Niklas Cassel)

Sophgo PCIe controller driver:

- Add DT binding and driver for Sophgo SG2044 PCIe controller driver
in Root Complex mode (Inochi Amaoto)

Synopsys DesignWare PCIe controller driver:

- Add required PCIE_RESET_CONFIG_WAIT_MS after waiting for Link up on
Ports that support > 5.0 GT/s. Slower Ports still rely on the
not-quite-correct PCIE_LINK_WAIT_SLEEP_MS 90ms default delay while
waiting for the Link (Niklas Cassel)"
