Merge tag 'pci-v5.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull pci updates from Bjorn Helgaas: "Enumeration: - Conserve IRQs by setting up portdrv IRQs only when there are users (Jan Kiszka) - Rework and simplify _OSC negotiation for control of PCIe features (Joerg Roedel) - Remove struct pci_dev.driver pointer since it's redundant with the struct device.driver pointer (Uwe Kleine-König) Resource management: - Coalesce contiguous host bridge apertures from _CRS to accommodate BARs that cover more than one aperture (Kai-Heng Feng) Sysfs: - Check CAP_SYS_ADMIN before parsing user input (Krzysztof Wilczyński) - Return -EINVAL consistently from "store" functions (Krzysztof Wilczyński) - Use sysfs_emit() in endpoint "show" functions to avoid buffer overruns (Kunihiko Hayashi) PCIe native device hotplug: - Ignore Link Down/Up caused by resets during error recovery so endpoint drivers can remain bound to the device (Lukas Wunner) Virtualization: - Avoid bus resets on Atheros QCA6174, where they hang the device (Ingmar Klein) - Work around Pericom PI7C9X2G switch packet drop erratum by using store and forward mode instead of cut-through (Nathan Rossi) - Avoid trying to enable AtomicOps on VFs; the PF setting applies to all VFs (Selvin Xavier) MSI: - Document that /sys/bus/pci/devices/.../irq contains the legacy INTx interrupt or the IRQ of the first MSI (not MSI-X) vector (Barry Song) VPD: - Add pci_read_vpd_any() and pci_write_vpd_any() to access anywhere in the possible VPD space; use these to simplify the cxgb3 driver (Heiner Kallweit) Peer-to-peer DMA: - Add (not subtract) the bus offset when calculating DMA address (Wang Lu) ASPM: - Re-enable LTR at Downstream Ports so they don't report Unsupported Requests when reset or hot-added devices send LTR messages (Mingchuang Qiao) Apple PCIe controller driver: - Add driver for Apple M1 PCIe controller (Alyssa Rosenzweig, Marc Zyngier) Cadence PCIe controller driver: - Return success when probe succeeds instead of falling into error path (Li Chen) HiSilicon Kirin PCIe controller driver: - Reorganize PHY logic and add support for external PHY drivers (Mauro Carvalho Chehab) - Support PERST# GPIOs for HiKey970 external PEX 8606 bridge (Mauro Carvalho Chehab) - Add Kirin 970 support (Mauro Carvalho Chehab) - Make driver removable (Mauro Carvalho Chehab) Intel VMD host bridge driver: - If IOMMU supports interrupt remapping, leave VMD MSI-X remapping enabled (Adrian Huang) - Number each controller so we can tell them apart in /proc/interrupts (Chunguang Xu) - Avoid building on UML because VMD depends on x86 bare metal APIs (Johannes Berg) Marvell Aardvark PCIe controller driver: - Define macros for PCI_EXP_DEVCTL_PAYLOAD_* (Pali Rohár) - Set Max Payload Size to 512 bytes per Marvell spec (Pali Rohár) - Downgrade PIO Response Status messages to debug level (Marek Behún) - Preserve CRS SV (Config Request Retry Software Visibility) bit in emulated Root Control register (Pali Rohár) - Fix issue in configuring reference clock (Pali Rohár) - Don't clear status bits for masked interrupts (Pali Rohár) - Don't mask unused interrupts (Pali Rohár) - Avoid code repetition in advk_pcie_rd_conf() (Marek Behún) - Retry config accesses on CRS response (Pali Rohár) - Simplify emulated Root Capabilities initialization (Pali Rohár) - Fix several link training issues (Pali Rohár) - Fix link-up checking via LTSSM (Pali Rohár) - Fix reporting of Data Link Layer Link Active (Pali Rohár) - Fix emulation of W1C bits (Marek Behún) - Fix MSI domain .alloc() method to return zero on success (Marek Behún) - Read entire 16-bit MSI vector in MSI handler, not just low 8 bits (Marek Behún) - Clear Root Port I/O Space, Memory Space, and Bus Master Enable bits at startup; PCI core will set those as necessary (Pali Rohár) - When operating as a Root Port, set class code to "PCI Bridge" instead of the default "Mass Storage Controller" (Pali Rohár) - Add emulation for PCI_BRIDGE_CTL_BUS_RESET since aardvark doesn't implement this per spec (Pali Rohár) - Add emulation of option ROM BAR since aardvark doesn't implement this per spec (Pali Rohár) MediaTek MT7621 PCIe controller driver: - Add MediaTek MT7621 PCIe host controller driver and DT binding (Sergio Paracuellos) Qualcomm PCIe controller driver: - Add SC8180x compatible string (Bjorn Andersson) - Add endpoint controller driver and DT binding (Manivannan Sadhasivam) - Restructure to use of_device_get_match_data() (Prasad Malisetty) - Add SC7280-specific pcie_1_pipe_clk_src handling (Prasad Malisetty) Renesas R-Car PCIe controller driver: - Remove unnecessary includes (Geert Uytterhoeven) Rockchip DesignWare PCIe controller driver: - Add DT binding (Simon Xue) Socionext UniPhier Pro5 controller driver: - Serialize INTx masking/unmasking (Kunihiko Hayashi) Synopsys DesignWare PCIe controller driver: - Run dwc .host_init() method before registering MSI interrupt handler so we can deal with pending interrupts left by bootloader (Bjorn Andersson) - Clean up Kconfig dependencies (Andy Shevchenko) - Export symbols to allow more modular drivers (Luca Ceresoli) TI DRA7xx PCIe controller driver: - Allow host and endpoint drivers to be modules (Luca Ceresoli) - Enable external clock if present (Luca Ceresoli) TI J721E PCIe driver: - Disable PHY when probe fails after initializing it (Christophe JAILLET) MicroSemi Switchtec management driver: - Return error to application when command execution fails because an out-of-band reset has cleared the device BARs, Memory Space Enable, etc (Kelvin Cao) - Fix MRPC error status handling issue (Kelvin Cao) - Mask out other bits when reading of management VEP instance ID (Kelvin Cao) - Return EOPNOTSUPP instead of ENOTSUPP from sysfs show functions (Kelvin Cao) - Add check of event support (Logan Gunthorpe) Miscellaneous: - Remove unused pci_pool wrappers, which have been replaced by dma_pool (Cai Huoqing) - Use 'unsigned int' instead of bare 'unsigned' (Krzysztof Wilczyński) - Use kstrtobool() directly, sans strtobool() wrapper (Krzysztof Wilczyński) - Fix some sscanf(), sprintf() format mismatches (Krzysztof Wilczyński) - Update PCI subsystem information in MAINTAINERS (Krzysztof Wilczyński) - Correct some misspellings (Krzysztof Wilczyński)" * tag 'pci-v5.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: (137 commits) PCI: Add ACS quirk for Pericom PI7C9X2G switches PCI: apple: Configure RID to SID mapper on device addition iommu/dart: Exclude MSI doorbell from PCIe device IOVA range PCI: apple: Implement MSI support PCI: apple: Add INTx and per-port interrupt support PCI: kirin: Allow removing the driver PCI: kirin: De-init the dwc driver PCI: kirin: Disable clkreq during poweroff sequence PCI: kirin: Move the power-off code to a common routine PCI: kirin: Add power_off support for Kirin 960 PHY PCI: kirin: Allow building it as a module PCI: kirin: Add MODULE_* macros PCI: kirin: Add Kirin 970 compatible PCI: kirin: Support PERST# GPIOs for HiKey970 external PEX 8606 bridge PCI: apple: Set up reference clocks when probing PCI: apple: Add initial hardware bring-up PCI: of: Allow matching of an interrupt-map local to a PCI device of/irq: Allow matching of an interrupt-map local to an interrupt controller irqdomain: Make of_phandle_args_to_fwspec() generally available PCI: Do not enable AtomicOps on VFs ...
