Pull pci updates from Bjorn Helgaas: "Enumeration: - Move the VGA arbiter from drivers/gpu to drivers/pci because it's PCI-specific, not GPU-specific (Bjorn Helgaas) - Select the default VGA device consistently whether it's enumerated before or after VGA arbiter init, which fixes arches that enumerate PCI devices late (Huacai Chen) Resource management: - Support BAR sizes up to 8TB (Dongdong Liu) PCIe native device hotplug: - Fix "Command Completed" tracking to avoid spurious timouts when powering off empty slots (Liguang Zhang) - Quirk Qualcomm devices that don't implement Command Completed correctly, again to avoid spurious timeouts (Manivannan Sadhasivam) Peer-to-peer DMA: - Add Intel 3rd Gen Intel Xeon Scalable Processors to whitelist (Michael J. Ruhl) APM X-Gene PCIe controller driver: - Revert generic DT parsing changes that broke some machines in the field (Marc Zyngier) Freescale i.MX6 PCIe controller driver: - Allow controller probe to succeed even when no devices currently present to allow hot-add later (Fabio Estevam) - Enable power management on i.MX6QP (Richard Zhu) - Assert CLKREQ# on i.MX8MM so enumeration doesn't hang when no device is connected (Richard Zhu) Marvell Aardvark PCIe controller driver: - Fix MSI and MSI-X support (Marek Behún, Pali Rohár) - Add support for ERR and PME interrupts (Pali Rohár) Marvell MVEBU PCIe controller driver: - Add DT binding and support for "num-lanes" (Pali Rohár) - Add support for INTx interrupts (Pali Rohár) Microsoft Hyper-V host bridge driver: - Avoid unnecessary hypercalls when unmasking IRQs on ARM64 (Boqun Feng) Qualcomm PCIe controller driver: - Add SM8450 DT binding and driver support (Dmitry Baryshkov) Renesas R-Car PCIe controller driver: - Help the controller get to the L1 state since the hardware can't do it on its own (Marek Vasut) - Return PCI_ERROR_RESPONSE (~0) for reads that fail on PCIe (Marek Vasut) SiFive FU740 PCIe controller driver: - Drop redundant '-gpios' from DT GPIO lookup (Ben Dooks) - Force 2.5GT/s for initial device probe (Ben Dooks) Socionext UniPhier Pro5 controller driver: - Add NX1 DT binding and driver support (Kunihiko Hayashi) Synopsys DesignWare PCIe controller driver: - Restore MSI configuration so MSI works after resume (Jisheng Zhang)" * tag 'pci-v5.18-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: (94 commits) x86/PCI: Add #includes to asm/pci_x86.h PCI: ibmphp: Remove unused assignments PCI: cpqphp: Remove unused assignments PCI: fu740: Remove unused assignments PCI: kirin: Remove unused assignments PCI: Remove unused assignments PCI: Declare pci_filp_private only when HAVE_PCI_MMAP PCI: Avoid broken MSI on SB600 USB devices PCI: fu740: Force 2.5GT/s for initial device probe PCI: xgene: Revert "PCI: xgene: Fix IB window setup" PCI: xgene: Revert "PCI: xgene: Use inbound resources for setup" PCI: imx6: Assert i.MX8MM CLKREQ# even if no device present PCI: imx6: Invoke the PHY exit function after PHY power off PCI: rcar: Use PCI_SET_ERROR_RESPONSE after read which triggered an exception PCI: rcar: Finish transition to L1 state in rcar_pcie_config_access() PCI: dwc: Restore MSI Receiver mask during resume PCI: fu740: Drop redundant '-gpios' from DT GPIO lookup PCI/VGA: Replace full MIT license text with SPDX identifier PCI/VGA: Use unsigned format string to print lock counts PCI/VGA: Log bridge control messages when adding devices ...
