  Merge branch 'pci/misc' (2023-08-29 11:03:57 -0500)

----------------------------------------------------------------

Enumeration:

  - Add locking to read/modify/write PCIe Capability Register accessors for
    Link Control and Root Control

  - Use pci_dev_id() when possible instead of manually composing ID from
    dev->bus->number and dev->devfn

Resource management:

  - Move prototypes for __weak sysfs resource files to linux/pci.h to fix
    "no previous prototype" warnings

  - Make more I/O port accesses depend on HAS_IOPORT

  - Use devm_platform_get_and_ioremap_resource() instead of open-coding
    platform_get_resource() followed by devm_ioremap_resource()

Power management:

  - Ensure devices are powered up while accessing VPD

  - If device is powered-up, keep it that way while polling for PME

  - Only read PCI_PM_CTRL register when available, to avoid reading the
    wrong register and corrupting dev->current_state

Virtualization:

  - Avoid Secondary Bus Reset on NVIDIA T4 GPUs

Error handling:

  - Remove unused pci_disable_pcie_error_reporting()

  - Unexport pci_enable_pcie_error_reporting(), used only by aer.c

  - Unexport pcie_port_bus_type, used only by PCI core

VGA:

  - Simplify and clean up typos in VGA arbiter

Apple PCIe controller driver:

  - Initialize pcie->nvecs (number of available MSIs) before use

Broadcom iProc PCIe controller driver:

  - Use of_property_read_bool() instead of low-level accessors for boolean
    properties

Broadcom STB PCIe controller driver:

  - Assert PERST# when probing BCM2711 because some bootloaders don't do it

Freescale i.MX6 PCIe controller driver:

  - Add .host_deinit() callback so we can clean up things like regulators
    on probe failure or driver unload

Freescale Layerscape PCIe controller driver:

  - Add support for link-down notification so the endpoint driver can
    process LINK_DOWN events

  - Add suspend/resume support, including manual PME_Turn_off/PME_TO_Ack
    handshake

  - Save Link Capabilities during probe so they can be restored when
    handling a link-up event, since the controller loses the Link Width and
    Link Speed values during reset

Intel VMD host bridge driver:

  - Fix disable of bridge windows during domain reset; previously we
    cleared the base/limit registers, which actually left the windows
    enabled

Marvell MVEBU PCIe controller driver:

  - Remove unused busn member

Microchip PolarFlare PCIe controller driver:

  - Fix interrupt bit definitions so the SEC and DED interrupt handlers
    work correctly

  - Make driver buildable as a module

  - Read FPGA MSI configuration parameters from hardware instead of
    hard-coding them

Microsoft Hyper-V host bridge driver:

  - To avoid a NULL pointer dereference, skip MSI restore after hibernate
    if MSI/MSI-X hasn't been enabled

NVIDIA Tegra194 PCIe controller driver:

  - Revert "PCI: tegra194: Enable support for 256 Byte payload" because
    Linux doesn't know how to reduce MPS from to 256 to 128 bytes for
    Endpoints below a Switch (because other devices below the Switch might
    already be operating), which leads to Malformed TLP errors

Qualcomm PCIe controller driver:

  - Add DT and driver support for interconnect bandwidth voting for
    "pcie-mem" and "cpu-pcie" interconnects

  - Fix broken SDX65 "compatible" DT property

  - Configure controller so MHI bus master clock will be switched off while
    in ASPM L1.x states

  - Use alignment restriction from EPF core in EPF MHI driver

  - Add Endpoint eDMA support

  - Add MHI eDMA support

  - Add Snapdragon SM8450 support to the EPF MHI driversupport

  - Add MHI eDMA support

  - Add Snapdragon SM8450 support to the EPF MHI driversupport

  - Add MHI eDMA support

  - Add Snapdragon SM8450 support to the EPF MHI driversupport

  - Add MHI eDMA support

  - Add Snapdragon SM8450 support to the EPF MHI driver

  - Use iATU for EPF MHI transfers smaller than 4K to avoid eDMA setup
    latency

  - Add sa8775p DT binding and driver support

Rockchip PCIe controller driver:

  - Use 64-bit mask on MSI 64-bit PCI address to avoid zeroing out the
    upper 32 bits

SiFive FU740 PCIe controller driver:

  - Set the supported number of MSI vectors so we can use all available MSI
    interrupts

Synopsys DesignWare PCIe controller driver:

  - Add generic dwc suspend/resume APIs (dw_pcie_suspend_noirq() and
    dw_pcie_resume_noirq()) to be called by controller driver
    suspend/resume ops, and a controller callback to send PME_Turn_Off

MicroSemi Switchtec management driver:

  - Add support for PCIe Gen5 devices

Miscellaneous:

  - Reorder and compress to reduce size of struct pci_dev

  - Fix race in DOE destroy_work_on_stack()

  - Add stubs to avoid casts between incompatible function types

  - Explicitly include correct DT includes to untangle headers
