Merge tag 'pci-v6.11-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
"Enumeration:

- Define PCIE_RESET_CONFIG_DEVICE_WAIT_MS for the generic 100ms
required after reset before config access (Kevin Xie)

- Define PCIE_T_RRS_READY_MS for the generic 100ms required after
reset before config access (probably should be unified with
PCIE_RESET_CONFIG_DEVICE_WAIT_MS) (Damien Le Moal)

Resource management:

- Rename find_resource() to find_resource_space() to be more
descriptive (Ilpo Järvinen)

- Export find_resource_space() for use by PCI core, which needs to
learn whether there is available space for a bridge window (Ilpo
Järvinen)

- Prevent double counting of resources so window size doesn't grow on
each remove/rescan cycle (Ilpo Järvinen)

- Relax bridge window sizing algorithm so a device doesn't break
simply because it was removed and rescanned (Ilpo Järvinen)

- Evaluate the ACPI PRESERVE_BOOT_CONFIG _DSM in
pci_register_host_bridge() (not acpi_pci_root_create()) so we can
unify it with similar DT functionality (Vidya Sagar)

per-host bridge as well as globally (Vidya Sagar)

- Unify support for ACPI PRESERVE_BOOT_CONFIG _DSM and the DT
"linux,pci-probe-only" property in pci_preserve_config() (Vidya
Sagar)

Driver binding:

BAR resources (Philipp Stanner)

- Deprecate pcim_iomap_table() because uses like
"pcim_iomap_table()[0]" have no good way to return errors (Philipp
Stanner)

- Add an always-managed pcim_request_region() for use instead of
pci_request_region() and similar, which are sometimes managed
depending on whether pcim_enable_device() has been called
previously (Philipp Stanner)

- Reimplement pcim_set_mwi() so it doesn't need to keep store MWI
state (Philipp Stanner)

managed depending on whether pcim_enable_device() has been called
previously (Philipp Stanner)

Merge tag 'pci-v6.8-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
"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)

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)

Shimoda)

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

Merge tag 'pci-v6.7-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
"Enumeration:

- 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
Järvinen)

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

- 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)

IOMMU:

- 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)

ASPM:

- 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
Shimoda)

Qualcomm PCIe controller driver:

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

- 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 Shimoda)

- 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)

Miscellaneous:

- 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
Sanpe)

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