Merge tag 'pci-v5.2-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI updates from Bjorn Helgaas: "Enumeration changes: - Add _HPX Type 3 settings support, which gives firmware more influence over device configuration (Alexandru Gagniuc) - Support fixed bus numbers from bridge Enhanced Allocation capabilities (Subbaraya Sundeep) - Add "external-facing" DT property to identify cases where we require IOMMU protection against untrusted devices (Jean-Philippe Brucker) - Enable PCIe services for host controller drivers that use managed host bridge alloc (Jean-Philippe Brucker) - Log PCIe port service messages with pci_dev, not the pcie_device (Frederick Lawler) - Convert pciehp from pciehp_debug module parameter to generic dynamic debug (Frederick Lawler) Peer-to-peer DMA: - Add whitelist of Root Complexes that support peer-to-peer DMA between Root Ports (Christian König) Native controller drivers: - Add PCI host bridge DMA ranges for bridges that can't DMA everywhere, e.g., iProc (Srinath Mannam) - Add Amazon Annapurna Labs PCIe host controller driver (Jonathan Chocron) - Fix Tegra MSI target allocation so DMA doesn't generate unwanted MSIs (Vidya Sagar) - Fix of_node reference leaks (Wen Yang) - Fix Hyper-V module unload & device removal issues (Dexuan Cui) - Cleanup R-Car driver (Marek Vasut) - Cleanup Keystone driver (Kishon Vijay Abraham I) - Cleanup i.MX6 driver (Andrey Smirnov) Significant bug fixes: - Reset Lenovo ThinkPad P50 GPU so nouveau works after reboot (Lyude Paul) - Fix Switchtec firmware update performance issue (Wesley Sheng) - Work around Pericom switch link retraining erratum (Stefan Mätje)" * tag 'pci-v5.2-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: (141 commits) MAINTAINERS: Add Karthikeyan Mitran and Hou Zhiqiang for Mobiveil PCI PCI: pciehp: Remove pointless MY_NAME definition PCI: pciehp: Remove pointless PCIE_MODULE_NAME definition PCI: pciehp: Remove unused dbg/err/info/warn() wrappers PCI: pciehp: Log messages with pci_dev, not pcie_device PCI: pciehp: Replace pciehp_debug module param with dyndbg PCI: pciehp: Remove pciehp_debug uses PCI/AER: Log messages with pci_dev, not pcie_device PCI/DPC: Log messages with pci_dev, not pcie_device PCI/PME: Replace dev_printk(KERN_DEBUG) with dev_info() PCI/AER: Replace dev_printk(KERN_DEBUG) with dev_info() PCI: Replace dev_printk(KERN_DEBUG) with dev_info(), etc PCI: Replace printk(KERN_INFO) with pr_info(), etc PCI: Use dev_printk() when possible PCI: Cleanup setup-bus.c comments and whitespace PCI: imx6: Allow asynchronous probing PCI: dwc: Save root bus for driver remove hooks PCI: dwc: Use devm_pci_alloc_host_bridge() to simplify code PCI: dwc: Free MSI in dw_pcie_host_init() error path PCI: dwc: Free MSI IRQ page in dw_pcie_free_msi() ...
