  Merge branch 'pci/typos' (2024-11-25 13:41:00 -0600)


NB:

  - Rebased this morning to remove duplicate commits.  Result is git
    diff-identical to 0f3d0b32cf72, which has been in linux-next since
    Nov 22.

  - Conflict in drivers/pci/probe.c between existing 1d59d474e1cb ("PCI:
    Hold rescan lock while adding devices during host probe") and new
    dc421bb3c0db ("PCI: Enable runtime PM of the host bridge").

  - Conflict in drivers/pci/pwrctrl/pci-pwrctrl-pwrseq.c between existing
    ad783b9f8e78 ("PCI/pwrctl: Abandon QCom WCN probe on pre-pwrseq
    device-trees") and new 086bf79a4d45 ("PCI/pwrctrl: Rename pwrctl files
    to pwrctrl") and e826ea4c7f26 ("PCI/pwrctrl: Rename pwrctrl functions
    and structures").  Note the names in pci_pwrctrl_pwrseq_of_match[]
    that need to be updated but aren't flagged as a conflict.
 
----------------------------------------------------------------

Enumeration:

  - Make pci_stop_dev() and pci_destroy_dev() safe so concurrent callers
    can't stop a device multiple times, even as we migrate from the global
    pci_rescan_remove_lock to finer-grained locking (Keith Busch)

  - Improve pci_walk_bus() implementation by making it recursive and moving
    locking up to avoid need for a 'locked' parameter (Keith Busch)

  - Unexport pci_walk_bus_locked(), which is only used internally by the
    PCI core (Keith Busch)

  - Detect some Thunderbolt chips that are built-in and hence 'trustworthy'
    by a heuristic since the 'ExternalFacingPort' and 'usb4-host-interface'
    ACPI properties are not quite enough (Esther Shimanovich)

Resource management:

  - Use PCI bus addresses (not CPU addresses) in 'ranges' properties when
    building dynamic DT nodes so systems where PCI and CPU addresses differ
    work correctly (Andrea della Porta)

  - Tidy resource sizing and assignment with helpers to reduce redundancy
    (Ilpo Järvinen)

  - Improve pdev_sort_resources() 'bogus alignment' warning to be more
    specific (Ilpo Järvinen)

Driver binding:

  - Convert driver .remove_new() callbacks to .remove() again to finish the
    conversion from returning 'int' to being 'void' (Sergio Paracuellos)

  - Export pcim_request_all_regions(), a managed interface to request all
    BARs (Philipp Stanner)

  - Replace pcim_iomap_regions_request_all() with
    pcim_request_all_regions(), and pcim_iomap_table()[n] with
    pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
    octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
    (Philipp Stanner)

  - Remove the now unused pcim_iomap_regions_request_all() (Philipp
    Stanner)

  - Export pcim_iounmap_region(), a managed interface to unmap and release
    a PCI BAR (Philipp Stanner)

  - Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
    pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
    following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
    cavium (Philipp Stanner)

Error handling:

  - Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
    bridge; previously Secondary Bus Reset could only be used when there
    was a single device below a bridge (Keith Busch)

  - Warn if we reset a running device where the driver didn't register
    pci_error_handlers notification callbacks (Keith Busch)

ASPM:

  - Disable ASPM L1 before touching L1 PM Substates to follow the spec
    closer and avoid a CPU load timeout on some platforms (Ajay Agarwal)

  - Set devices below Intel VMD to D0 before enabling ASPM L1 Substates as
    required per spec for all L1 Substates changes (Jian-Hong Pan)

Power management:

  - Enable starfive controller runtime PM before probing host bridge
    (Mayank Rana)

  - Enable runtime power management for host bridges (Krishna chaitanya
    chundru)

Power control:

  - Use of_platform_device_create() instead of of_platform_populate() to
    create pwrctl platform devices so we can control it based on the child
    nodes (Manivannan Sadhasivam)

  - Create pwrctrl platform devices only if there's a relevant power supply
    property (Manivannan Sadhasivam)

  - Add device link from the pwrctl supplier to the PCI dev to ensure
    pwrctl drivers are probed before the PCI dev driver; this avoids a race
    where pwrctl could change device power state while the PCI driver was
    active (Manivannan Sadhasivam)

  - Find pwrctl device for removal with of_find_device_by_node() instead of
    searching all children of the parent (Manivannan Sadhasivam)

  - Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
    ('bwctrl') and hotplug files (Bjorn Helgaas)

Bandwidth control:

  - Add read/modify/write locking for Link Control 2, which is used to
    manage Link speed (Ilpo Järvinen)

  - Extract Link Bandwidth Management Status check into pcie_lbms_seen(),
    where it can be shared between the bandwidth controller and quirks that
    use it to help retrain failed links (Ilpo Järvinen)

  - Re-add Link Bandwidth notification support with updates to address the
    reasons it was previously reverted (Alexandru Gagniuc, Ilpo Järvinen)

  - Add pcie_set_target_speed() and related functionality so drivers can
    manage PCIe Link speed based on thermal or other constraints (Ilpo
    Järvinen)

  - Add a thermal cooling driver to throttle PCIe Links via the existing
    thermal management framework (Ilpo Järvinen)

  - Add a userspace selftest for the PCIe bandwidth controller (Ilpo
    Järvinen)

PCI device hotplug:

  - Add hotplug controller driver for Marvell OCTEON multi-function device
    where function 0 has a management console interface to enable/disable
    and provision various personalities for the other functions (Shijith
    Thotton)

  - Retain a reference to the pci_bus for the lifetime of a pci_slot to
    avoid a use-after-free when the thunderbolt driver resets USB4 host
    routers on boot, causing hotplug remove/add of downstream docks or
    other devices (Lukas Wunner)

  - Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
    (Guilherme Giacomo Simoes)

  - Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)

  - Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
    detection in cpqphp (Ilpo Järvinen)

  - Simplify cpqphp enumeration, which is already simple-minded and doesn't
    handle devices below hot-added bridges (Ilpo Järvinen)

Virtualization:

  - Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
    capability but do isolate functions as though PCI_ACS_RR and PCI_ACS_CR
    were set, so the functions can be in independent IOMMU groups (Mengyuan
    Lou)

TLP Processing Hints (TPH):

  - Add and document TLP Processing Hints (TPH) support so drivers can
    enable and disable TPH and the kernel can save/restore TPH
    configuration (Wei Huang)

  - Add TPH Steering Tag support so drivers can retrieve Steering Tag
    values associated with specific CPUs via an ACPI _DSM to improve
    performance by directing DMA writes closer to their consumers (Wei
    Huang)

Data Object Exchange (DOE):

  - Wait up to 1 second for DOE Busy bit to clear before writing a request
    to the mailbox to avoid failures if the mailbox is still busy from a
    previous transfer (Gregory Price)

Endpoint framework:

  - Skip attempts to allocate from endpoint controller memory window if the
    requested size is larger than the window (Damien Le Moal)

  - Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to handle
    controller-specific size and alignment constraints, and add test cases
    to the endpoint test driver (Damien Le Moal)

  - Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can observe
    DWC-specific alignment requirements (Damien Le Moal)

  - Synchronously cancel command handler work in endpoint test before
    cleaning up DMA and BARs (Damien Le Moal)

  - Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas Cassel)

  - Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
    dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
    (Niklas Cassel)

  - Avoid NULL dereference if Modem Host Interface Endpoint lacks 'mmio' DT
    property (Zhongqiu Han)

  - Release PCI domain ID of Endpoint controller parent (not controller
    itself) and before unregistering the controller, to avoid
    use-after-free (Zijun Hu)

  - Clear secondary (not primary) EPC in pci_epc_remove_epf() when removing
    the secondary controller associated with an NTB (Zijun Hu)

Cadence PCIe controller driver:

  - Lower severity of 'phy-names' message (Bartosz Wawrzyniak)

Freescale i.MX6 PCIe controller driver:

  - Fix suspend/resume support on i.MX6QDL, which has a hardware erratum
    that prevents use of L2 (Stefan Eichenberger)

Intel VMD host bridge driver:

  - Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)

MediaTek PCIe Gen3 controller driver:

  - Update mediatek-gen3 DT binding to require the exact number of clocks
    for each SoC (Fei Shao)

  - Add support for DT 'max-link-speed' and 'num-lanes' properties to
    restrict the link speed and width (AngeloGioacchino Del Regno)

Microchip PolarFlare PCIe controller driver:

  - Add DT and driver support for using either of the two PolarFire Root
    Ports (Conor Dooley)

NVIDIA Tegra194 PCIe controller driver:

  - Move endpoint controller cleanups that depend on refclk from the host
    to the notifier that tells us the host has deasserted PERST#, when
    refclk should be valid (Manivannan Sadhasivam)

Qualcomm PCIe controller driver:

  - Add qcom SAR2130P DT binding with an additional clock (Dmitry
    Baryshkov)

  - Enable MSI interrupts if 'global' IRQ is supported, since a previous
    commit unintentionally masked them (Manivannan Sadhasivam)

  - Move endpoint controller cleanups that depend on refclk from the host
    to the notifier that tells us the host has deasserted PERST#, when
    refclk should be valid (Manivannan Sadhasivam)

  - Add DT binding and driver support for IPQ9574, with Synopsys IP v5.80a
    and Qcom IP 1.27.0 (devi priya)

  - Move the OPP "operating-points-v2" table from the qcom,pcie-sm8450.yaml
    DT binding to qcom,pcie-common.yaml, where it can be used by other Qcom
    platforms (Qiang Yu)

  - Add 'global' SPI interrupt for events like link-up, link-down to
    qcom,pcie-x1e80100 DT binding so we can start enumeration when the link
    comes up (Qiang Yu)

  - Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned to
    support this (Qiang Yu)

  - Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
    'iommu-map' DT property and doesn't need BDF-to-SID translation (Qiang
    Yu)

Rockchip PCIe controller driver:

  - Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint .align
    value (Damien Le Moal)

  - When unmapping an endpoint window, compute the region index instead of
    searching for it, and verify that the address was mapped (Damien Le
    Moal)

  - When mapping an endpoint window, verify that the address hasn't been
    mapped already (Damien Le Moal)

  - Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)

  - Fix MSI IRQ data mapping to observe the alignment constraint, which
    fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
    (Damien Le Moal)

  - Rename rockchip_pcie_parse_ep_dt() to rockchip_pcie_ep_get_resources()
    for consistency with similar DT interfaces (Damien Le Moal)

  - Skip the unnecessary link train in rockchip_pcie_ep_probe() and do it
    only in the endpoint start operation (Damien Le Moal)

  - Implement pci_epc_ops.stop_link() to disable link training and
    controller configuration (Damien Le Moal)

  - Attempt link training at 5 GT/s when both partners support it (Damien
    Le Moal)

  - Add a handler for PERST# signal so we can detect host-initiated resets
    and start link training after PERST# is deasserted (Damien Le Moal)

Synopsys DesignWare PCIe controller driver:

  - Clear outbound address on unmap so dw_pcie_find_index() won't match an
    ATU index that was already unmapped (Damien Le Moal)

  - Use of_property_present() instead of of_property_read_bool() when
    testing for presence of non-boolean DT properties (Rob Herring)

  - Advertise 1MB size if endpoint supports Resizable BARs, which was
    inadvertently lost in v6.11 (Niklas Cassel)

TI J721E PCIe driver:

  - Add PCIe support for J722S SoC (Siddharth Vadapalli)

  - Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100 us),
    before deasserting PERST# to ensure power and refclk are stable
    (Siddharth Vadapalli)

TI Keystone PCIe controller driver:

  - Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root Complex
    mode (Kishon Vijay Abraham I)

  - Try to avoid unrecoverable SError for attempts to issue config
    transactions when the link is down; this is racy but the best we can do
    (Kishon Vijay Abraham I)

Miscellaneous:

  - Reorganize kerneldoc parameter names to match order in function
    signature (Julia Lawall)
