  Merge branch 'pci/misc' (2024-01-15 12:10:41 -0600)

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

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)
