Merge tag 'pci-v4.18-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI updates from Bjorn Helgaas: - unify AER decoding for native and ACPI CPER sources (Alexandru Gagniuc) - add TLP header info to AER tracepoint (Thomas Tai) - add generic pcie_wait_for_link() interface (Oza Pawandeep) - handle AER ERR_FATAL by removing and re-enumerating devices, as Downstream Port Containment does (Oza Pawandeep) - factor out common code between AER and DPC recovery (Oza Pawandeep) - stop triggering DPC for ERR_NONFATAL errors (Oza Pawandeep) - share ERR_FATAL recovery path between AER and DPC (Oza Pawandeep) - disable ASPM L1.2 substate if we don't have LTR (Bjorn Helgaas) - respect platform ownership of LTR (Bjorn Helgaas) - clear interrupt status in top half to avoid interrupt storm (Oza Pawandeep) - neaten pci=earlydump output (Andy Shevchenko) - avoid errors when extended config space inaccessible (Gilles Buloz) - prevent sysfs disable of device while driver attached (Christoph Hellwig) - use core interface to report PCIe link properties in bnx2x, bnxt_en, cxgb4, ixgbe (Bjorn Helgaas) - remove unused pcie_get_minimum_link() (Bjorn Helgaas) - fix use-before-set error in ibmphp (Dan Carpenter) - fix pciehp timeouts caused by Command Completed errata (Bjorn Helgaas) - fix refcounting in pnv_php hotplug (Julia Lawall) - clear pciehp Presence Detect and Data Link Layer Status Changed on resume so we don't miss hotplug events (Mika Westerberg) - only request pciehp control if we support it, so platform can use ACPI hotplug otherwise (Mika Westerberg) - convert SHPC to be builtin only (Mika Westerberg) - request SHPC control via _OSC if we support it (Mika Westerberg) - simplify SHPC handoff from firmware (Mika Westerberg) - fix an SHPC quirk that mistakenly included *all* AMD bridges as well as devices from any vendor with device ID 0x7458 (Bjorn Helgaas) - assign a bus number even to non-native hotplug bridges to leave space for acpiphp additions, to fix a common Thunderbolt xHCI hot-add failure (Mika Westerberg) - keep acpiphp from scanning native hotplug bridges, to fix common Thunderbolt hot-add failures (Mika Westerberg) - improve "partially hidden behind bridge" messages from core (Mika Westerberg) - add macros for PCIe Link Control 2 register (Frederick Lawler) - replace IB/hfi1 custom macros with PCI core versions (Frederick Lawler) - remove dead microblaze and xtensa code (Bjorn Helgaas) - use dev_printk() when possible in xtensa and mips (Bjorn Helgaas) - remove unused pcie_port_acpi_setup() and portdrv_acpi.c (Bjorn Helgaas) - add managed interface to get PCI host bridge resources from OF (Jan Kiszka) - add support for unbinding generic PCI host controller (Jan Kiszka) - fix memory leaks when unbinding generic PCI host controller (Jan Kiszka) - request legacy VGA framebuffer only for VGA devices to avoid false device conflicts (Bjorn Helgaas) - turn on PCI_COMMAND_IO & PCI_COMMAND_MEMORY in pci_enable_device() like everybody else, not in pcibios_fixup_bus() (Bjorn Helgaas) - add generic enable function for simple SR-IOV hardware (Alexander Duyck) - use generic SR-IOV enable for ena, nvme (Alexander Duyck) - add ACS quirk for Intel 7th & 8th Gen mobile (Alex Williamson) - add ACS quirk for Intel 300 series (Mika Westerberg) - enable register clock for Armada 7K/8K (Gregory CLEMENT) - reduce Keystone "link already up" log level (Fabio Estevam) - move private DT functions to drivers/pci/ (Rob Herring) - factor out dwc CONFIG_PCI Kconfig dependencies (Rob Herring) - add DesignWare support to the endpoint test driver (Gustavo Pimentel) - add DesignWare support for endpoint mode (Gustavo Pimentel) - use devm_ioremap_resource() instead of devm_ioremap() in dra7xx and artpec6 (Gustavo Pimentel) - fix Qualcomm bitwise NOT issue (Dan Carpenter) - add Qualcomm runtime PM support (Srinivas Kandagatla) - fix DesignWare enumeration below bridges (Koen Vandeputte) - use usleep() instead of mdelay() in endpoint test (Jia-Ju Bai) - add configfs entries for pci_epf_driver device IDs (Kishon Vijay Abraham I) -
