Pull pci updates from Bjorn Helgaas: "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" * tag 'pci-v6.4-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci: (56 commits) PCI: xilinx: Drop obsolete dependency on COMPILE_TEST PCI: mobiveil: Sort Kconfig entries by vendor PCI: dwc: Sort Kconfig entries by vendor PCI: Sort controller Kconfig entries by vendor PCI: Use consistent controller Kconfig menu entry language PCI: xilinx-nwl: Add 'Xilinx' to Kconfig prompt PCI: hv: Add 'Microsoft' to Kconfig prompt PCI: meson: Add 'Amlogic' to Kconfig prompt PCI: Use of_property_present() for testing DT property presence PCI/PM: Extend D3hot delay for NVIDIA HDA controllers dt-bindings: PCI: qcom: Document msi-map and msi-map-mask properties PCI: qcom: Add SM8550 PCIe support dt-bindings: PCI: qcom: Add SM8550 compatible PCI: qcom: Add support for SDX55 SoC dt-bindings: PCI: qcom-ep: Fix the unit address used in example dt-bindings: PCI: qcom: Add SDX55 SoC dt-bindings: PCI: qcom: Update maintainers entry PCI: qcom: Enable async probe by default PCI: qcom: Add support for system suspend and resume PCI/PM: Drop pci_bridge_wait_for_secondary_bus() timeout parameter ...
