  Merge branch 'pci/misc' (2023-10-28 13:31:05 -0500)



  - Use acpi_evaluate_dsm_typed() instead of open-coding _DSM evaluation to
    learn device characteristics (Andy Shevchenko)

  - Tidy multi-function header checks using new PCI_HEADER_TYPE_MASK
    definition (Ilpo Järvinen)

  - Simplify config access error checking in various drivers (Ilpo

  - Use pcie_capability_clear_word() (not
    pcie_capability_clear_and_set_word()) when only clearing (Ilpo

  - Add pci_get_base_class() to simplify finding devices using base class
    only (ignoring subclass and programming interface) (Sui Jingfeng)

  - Add pci_is_vga(), which includes ancient PCI_CLASS_NOT_DEFINED_VGA
    devices from before the Class Code was added to PCI (Sui Jingfeng)

  - Use pci_is_vga() for vgaarb, sysfs "boot_vga", virtio, qxl to include
    ancient VGA devices (Sui Jingfeng)

Resource management:

  - Make pci_assign_unassigned_resources() non-init because sparc uses it
    after init (Randy Dunlap)

Driver binding:

  - Retain .remove() and .probe() callbacks (previously __init) because
    sysfs may cause them to be called later (Uwe Kleine-König)

  - Prevent xHCI driver from claiming AMD VanGogh USB3 DRD device, so it
    can be claimed by dwc3 instead (Vicki Pfau)

PCI device hotplug:

  - Add Ampere Altra Attention Indicator extension driver for acpiphp
    (D Scott Phillips)

Power management:

  - Quirk VideoPropulsion Torrent QN16e with longer delay after reset
    (Lukas Wunner)

  - Prevent users from overriding drivers that say we shouldn't use D3cold
    (Lukas Wunner)

  - Avoid PME from D3hot/D3cold for AMD Rembrandt and Phoenix USB4 because
    wakeup interrupts from those states don't work if amd-pmc has put the
    platform in a hardware sleep state (Mario Limonciello)


  - Disable ATS for Intel IPU E2000 devices with invalidation message
    endianness erratum (Bartosz Pawlowski)

Error handling:

  - Factor out interrupt enable/disable into helpers (Kai-Heng Feng)

Peer-to-peer DMA:

  - Fix flexible-array usage in struct pci_p2pdma_pagemap in case we ever
    use pagemaps with multiple entries (Gustavo A. R. Silva)


  - Revert a change that broke when drivers disabled L1 and users later
    enabled an L1.x substate via sysfs, and fix a similar issue when users
    disabled L1 via sysfs (Heiner Kallweit)

Endpoint framework:

  - Fix double free in __pci_epc_create() (Dan Carpenter)

  - Use IS_ERR_OR_NULL() to simplify endpoint core (Ruan Jinjie)

Cadence PCIe controller driver:

  - Drop unused "is_rc" member (Li Chen)

Freescale Layerscape PCIe controller driver:

  - Enable 64-bit addressing in endpoint mode (Guanhua Gao)

Intel VMD host bridge driver:

  - Fix multi-function header check (Ilpo Järvinen)

Microsoft Hyper-V host bridge driver:

  - Annotate struct hv_dr_state with __counted_by (Kees Cook)

NVIDIA Tegra194 PCIe controller driver:

  - Drop setting of LNKCAP_MLW (max link width) since dw_pcie_setup()
    already does this via dw_pcie_link_set_max_link_width() (Yoshihiro

Qualcomm PCIe controller driver:

  - Use PCIE_SPEED2MBS_ENC() to simplify encoding of link speed (Manivannan

  - Add a .write_dbi2() callback so DBI2 register writes, e.g., for setting
    the BAR size, work correctly (Manivannan Sadhasivam)

  - Enable ASPM for platforms that use 1.9.0 ops, because the PCI core
    doesn't enable ASPM states that haven't been enabled by the firmware
    (Manivannan Sadhasivam)

Renesas R-Car Gen4 PCIe controller driver:

  - Add DesignWare core support (set max link width, EDMA_UNROLL flag,
    .pre_init(), .deinit(), etc) for use by R-Car Gen4 driver (Yoshihiro

  - Add driver and DT schema for DesignWare-based Renesas R-Car Gen4
    controller in both host and endpoint mode (Yoshihiro Shimoda)

Xilinx NWL PCIe controller driver:

  - Update ECAM size to support 256 buses (Thippeswamy Havalige)

  - Stop setting bridge primary/secondary/subordinate bus numbers, since
    PCI core does this (Thippeswamy Havalige)

Xilinx XDMA controller driver:

  - Add driver and DT schema for Zynq UltraScale+ MPSoCs devices with
    Xilinx XDMA Soft IP (Thippeswamy Havalige)


  - Use FIELD_GET()/FIELD_PREP() to simplify and reduce use of _SHIFT
    macros (Ilpo Järvinen, Bjorn Helgaas)

  - Remove logic_outb(), _outw(), outl() duplicate declarations (John

  - Replace unnecessary UTF-8 in Kconfig help text because menuconfig
    doesn't render it correctly (Liu Song)
