Pull pci updates from Bjorn Helgaas: "Enumeration: - Reserve ECAM so we don't assign it to PCI BARs; this works around bugs where BIOS included ECAM in a PNP0A03 host bridge window, didn't reserve it via a PNP0C02 motherboard device, and didn't allocate space for SR-IOV VF BARs (Bjorn Helgaas) - Add MMCONFIG/ECAM debug logging (Bjorn Helgaas) - Rename 'MMCONFIG' to 'ECAM' to match spec usage (Bjorn Helgaas) - Log device type (Root Port, Switch Port, etc) during enumeration (Bjorn Helgaas) - Log bridges before downstream devices so the dmesg order is more logical (Bjorn Helgaas) - Log resource names (BAR 0, VF BAR 0, bridge window, etc) consistently instead of a mix of names and "reg 0x10" (Puranjay Mohan, Bjorn Helgaas) - Fix 64GT/s effective data rate calculation to use 1b/1b encoding rather than the 8b/10b or 128b/130b used by lower rates (Ilpo Järvinen) - Use PCI_HEADER_TYPE_* instead of literals in x86, powerpc, SCSI lpfc (Ilpo Järvinen) - Clean up open-coded PCIBIOS return code mangling (Ilpo Järvinen) Resource management: - Restructure pci_dev_for_each_resource() to avoid computing the address of an out-of-bounds array element (the bounds check was performed later so the element was never actually *read*, but it's nicer to avoid even computing an out-of-bounds address) (Andy Shevchenko) Driver binding: - Convert pci-host-common.c platform .remove() callback to .remove_new() returning 'void' since it's not useful to return error codes here (Uwe Kleine-König) - Convert exynos, keystone, kirin from .remove() to .remove_new(), which returns void instead of int (Uwe Kleine-König) - Drop unused struct pci_driver.node member (Mathias Krause) Virtualization: - Add ACS quirk for more Zhaoxin Root Ports (LeoLiuoc) Error handling: - Log AER errors as "Correctable" (not "Corrected") or "Uncorrectable" to match spec terminology (Bjorn Helgaas) - Decode Requester ID when no error info found instead of printing the raw hex value (Bjorn Helgaas) Endpoint framework: - Use a unique test pattern for each BAR in the pci_endpoint_test to make it easier to debug address translation issues (Niklas Cassel) Broadcom STB PCIe controller driver: - Add DT property "brcm,clkreq-mode" and driver support for different CLKREQ# modes to make ASPM L1.x states possible (Jim Quinlan) Freescale Layerscape PCIe controller driver: - Add suspend/resume support for Layerscape LS1043a and LS1021a, including software-managed PME_Turn_Off and transitions between L0, L2/L3_Ready Link states (Frank Li) MediaTek PCIe controller driver: - Clear MSI interrupt status before handler to avoid missing MSIs that occur after the handler (qizhong cheng) MediaTek PCIe Gen3 controller driver: - Update mediatek-gen3 translation window setup to handle MMIO space that is not a power of two in size (Jianjun Wang) Qualcomm PCIe controller driver: - Increase qcom iommu-map maxItems to accommodate SDX55 (five entries) and SDM845 (sixteen entries) (Krzysztof Kozlowski) - Describe qcom,pcie-sc8180x clocks and resets accurately (Krzysztof Kozlowski) - Describe qcom,pcie-sm8150 clocks and resets accurately (Krzysztof Kozlowski) - Correct the qcom "reset-name" property, previously incorrectly called "reset-names" (Krzysztof Kozlowski) - Document qcom,pcie-sm8650, based on qcom,pcie-sm8550 (Neil Armstrong) Renesas R-Car PCIe controller driver: - Replace of_device.h with explicit of.h include to untangle header usage (Rob Herring) - Add DT and driver support for optional miniPCIe 1.5v and 3.3v regulators on KingFisher (Wolfram Sang) SiFive FU740 PCIe controller driver: - Convert fu740 CONFIG_PCIE_FU740 dependency from SOC_SIFIVE to ARCH_SIFIVE (Conor Dooley) Synopsys DesignWare PCIe controller driver: - Align iATU mapping for endpoint MSI-X (Niklas Cassel) - Drop "host_" prefix from struct dw_pcie_host_ops members (Yoshihiro Shimoda) - Drop "ep_" prefix from struct dw_pcie_ep_ops members (Yoshihiro Shimoda) - Rename struct dw_pcie_ep_ops.func_conf_select() to .get_dbi_offset() to be more descriptive (Yoshihiro Shimoda) - Add Endpoint DBI accessors to encapsulate offset lookups (Yoshihiro Shimoda) TI J721E PCIe driver: - Add j721e DT and driver support for 'num-lanes' for devices that support x1, x2, or x4 Links (Matt Ranostay) - Add j721e DT compatible strings and driver support for j784s4 (Matt Ranostay) - Make TI J721E Kconfig depend on ARCH_K3 since the hardware is specific to those TI SoC parts (Peter Robinson) TI Keystone PCIe controller driver: - Hold power management references to all PHYs while enabling them to avoid a race when one provides clocks to others (Siddharth Vadapalli) Xilinx XDMA PCIe controller driver: - Remove redundant dev_err(), since platform_get_irq() and platform_get_irq_byname() already log errors (Yang Li) - Fix uninitialized symbols in xilinx_pl_dma_pcie_setup_irq() (Krzysztof Wilczyński) - Fix xilinx_pl_dma_pcie_init_irq_domain() error return when irq_domain_add_linear() fails (Harshit Mogalapalli) MicroSemi Switchtec management driver: - Do dma_mrpc cleanup during switchtec_pci_remove() to match its devm ioremapping in switchtec_pci_probe(). Previously the cleanup was done in stdev_release(), which used stale pointers if stdev->cdev happened to be open when the PCI device was removed (Daniel Stodden) Miscellaneous: - Convert interrupt terminology from "legacy" to "INTx" to be more specific and match spec terminology (Damien Le Moal) - In dw-xdata-pcie, pci_endpoint_test, and vmd, replace usage of deprecated ida_simple_*() API with ida_alloc() and ida_free() (Christophe JAILLET)" * tag 'pci-v6.8-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci: (97 commits) PCI: Fix kernel-doc issues PCI: brcmstb: Configure HW CLKREQ# mode appropriate for downstream device dt-bindings: PCI: brcmstb: Add property "brcm,clkreq-mode" PCI: mediatek-gen3: Fix translation window size calculation PCI: mediatek: Clear interrupt status before dispatching handler PCI: keystone: Fix race condition when initializing PHYs PCI: xilinx-xdma: Fix error code in xilinx_pl_dma_pcie_init_irq_domain() PCI: xilinx-xdma: Fix uninitialized symbols in xilinx_pl_dma_pcie_setup_irq() PCI: rcar-gen4: Fix -Wvoid-pointer-to-enum-cast error PCI: iproc: Fix -Wvoid-pointer-to-enum-cast warning PCI: dwc: Add dw_pcie_ep_{read,write}_dbi[2] helpers PCI: dwc: Rename .func_conf_select to .get_dbi_offset in struct dw_pcie_ep_ops PCI: dwc: Rename .ep_init to .init in struct dw_pcie_ep_ops PCI: dwc: Drop host prefix from struct dw_pcie_host_ops members misc: pci_endpoint_test: Use a unique test pattern for each BAR PCI: j721e: Make TI J721E depend on ARCH_K3 PCI: j721e: Add TI J784S4 PCIe configuration PCI/AER: Use explicit register sizes for struct members PCI/AER: Decode Requester ID when no error info found PCI/AER: Use 'Correctable' and 'Uncorrectable' spec terms for errors ...
