Merge tag 'pci-v4.11-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI updates from Bjorn Helgaas: - add ASPM L1 substate support - enable PCIe Extended Tags when supported - configure PCIe MPS settings on iProc, Versatile, X-Gene, and Xilinx - increase VPD access timeout - add ACS quirks for Intel Union Point, Qualcomm QDF2400 and QDF2432 - use new pci_irq_alloc_vectors() in more drivers - fix MSI affinity memory leak - remove unused MSI interfaces and update documentation - remove unused AER .link_reset() callback - avoid pci_lock / p->pi_lock deadlock seen with perf - serialize sysfs enable/disable num_vfs operations - move DesignWare IP from drivers/pci/host/ to drivers/pci/dwc/ and refactor so we can support both hosts and endpoints - add DT ECAM-like support for HiSilicon Hip06/Hip07 controllers - add Rockchip system power management support - add Thunder-X cn81xx and cn83xx support - add Exynos 5440 PCIe PHY support * tag 'pci-v4.11-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: (93 commits) PCI: dwc: Remove dependency of designware on CONFIG_PCI PCI: dwc: Add CONFIG_PCIE_DW_HOST to enable PCI dwc host PCI: dwc: Split pcie-designware.c into host and core files PCI: dwc: designware: Fix style errors in pcie-designware.c PCI: dwc: designware: Parse "num-lanes" property in dw_pcie_setup_rc() PCI: dwc: all: Split struct pcie_port into host-only and core structures PCI: dwc: designware: Get device pointer at the start of dw_pcie_host_init() PCI: dwc: all: Rename cfg_read/cfg_write to read/write PCI: dwc: all: Use platform_set_drvdata() to save private data PCI: dwc: designware: Move register defines to designware header file PCI: dwc: Use PTR_ERR_OR_ZERO to simplify code PCI: dra7xx: Group PHY API invocations PCI: dra7xx: Enable MSI and legacy interrupts simultaneously PCI: dra7xx: Add support to force RC to work in GEN1 mode PCI: dra7xx: Simplify probe code with devm_gpiod_get_optional() PCI: Move DesignWare IP support to new drivers/pci/dwc/ directory PCI: exynos: Support the PHY generic framework Documentation: binding: Modify the exynos5440 PCIe binding phy: phy-exynos-pcie: Add support for Exynos PCIe PHY Documentation: samsung-phy: Add exynos-pcie-phy binding ...
