Merge tag 'pci-v6.6-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
 "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 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

  Rockchip PCIe controller driver:
   - Use 64-bit mask on MSI 64-bit PCI address to avoid zeroing out the
     upper 32 bits

   - 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"

dt-bindings: PCI: qcom: ep: Add interconnects path
Some platforms may not boot if a device driver doesn't
initialize the interconnect path. Mostly it is handled
by the bootloader but we have starting to see cases
where bootloader simply ignores them.

Add the "pcie-mem" & "cpu-pcie" interconnect path as a required
property to the bindings.

dt-bindings: PCI: qcom: Fix SDX65 compatible
Commit c0aba9f328 ("dt-bindings: PCI: qcom: Add SDX65 SoC") adding
SDX65 was never tested and is clearly bogus.  The qcom,sdx65-pcie-ep
compatible is followed by a fallback in DTS, and there is no driver
matched by this compatible.  Driver matches by its fallback
qcom,sdx55-pcie-ep.  This also fixes dtbs_check warnings like:

  qcom-sdx65-mtp.dtb: pcie-ep@1c00000: compatible: ['qcom,sdx65-pcie-ep', 'qcom,sdx55-pcie-ep'] is too long

7cd8f2ab79 dt-bindings: PCI: dwc: rockchip: Add missing legacy-interrupt-controller
Rockchip RK356x and RK3588 handle legacy interrupts via a ganged
interrupts. The RK356x DT implements this via a sub-node named
"legacy-interrupt-controller", just like a couple of other PCIe
implementations. This adds proper documentation for this and updates
the example to avoid regressions.

ebce9f6623 dt-bindings: PCI: dwc: rockchip: Fix interrupt-names issue
The RK356x (and RK3588) have 5 ganged interrupts. For example the
"legacy" interrupt combines "inta/intb/intc/intd" with a register
providing the details, which specific interrupt triggered. The
interrupts from the second level are part of the Synopsys DW PCIe
System Information Interface (SII). Some of them are listed in the
Interrupt Signals section, the others are mostly common SII output
signals. The grouping and the ganged interrupt controllers are
specific to the Rockchip implementation.

Currently the binding is not specifying these interrupts resulting
in a bunch of errors for all rk356x/rk3588 boards using PCIe.

Fix this by specifying the interrupts and add them to the example
to prevent regressions.

This changes the reference from snps,dw-pcie.yaml to
snps,dw-pcie-common.yaml, since the interrupts are vendor
specific and should not be listed in the generic file. The
only other bit from the generic binding are the reg-names,
which are overwritten by this binding.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Export pcie_retrain_link() for use outside ASPM

   - Add Data Link Layer Link Active Reporting as another way for
     pcie_retrain_link() to determine the link is up

   - Work around link training failures (especially on the ASMedia
     ASM2824 switch) by training first at 2.5GT/s and then attempting
     higher rates

  Resource management:

   - When we coalesce host bridge windows, remove invalidated resources
     from the resource tree so future allocations work correctly

  Hotplug:

   - Cancel bringup sequence if card is not present, to keep from
     blinking Power Indicator indefinitely

   - Reassign bridge resources if necessary for ACPI hotplug

  Driver binding:

   - Convert platform_device .remove() callbacks to return void instead
     of a mostly useless int

  Power management:

   - Reduce wait time for secondary bus to be ready to speed up resume

   - Avoid putting EloPOS E2/S2/H2 (as well as Elo i2) PCIe Ports in
     D3cold

   - Call _REG when transitioning D-states so AML that uses the PCI
     config space OpRegion works, which fixes some ASMedia GPIO
     controllers after resume

  Virtualization:

   - Delay extra 250ms after FLR of Solidigm P44 Pro NVMe to avoid KVM
     hang when guest is rebooted

   - Add function 1 DMA alias quirk for Marvell 88SE9235

  Error handling:

   - Unexport pci_save_aer_state() since it's only used in drivers/pci/

   - Drop recommendation for drivers to configure AER Capability, since
     the PCI core does this for all devices

  ASPM:

   - Disable ASPM on MFD function removal to avoid use-after-free

   - Tighten up pci_enable_link_state() and pci_disable_link_state()
     interfaces so they don't enable/disable states the driver didn't
     specify

   - Avoid link retraining race that can happen if ASPM sets link
     control parameters while the link is in the midst of training for
     some other reason

  Endpoint framework:

   - Change "PCI Endpoint Virtual NTB driver" Kconfig prompt to be
     different from "PCI Endpoint NTB driver"

   - Automatically create a function specific attributes group for
     endpoint drivers to avoid reference counting issues

   - Fix many EPC test issues

   - Return pci_epf_type_add_cfs() error if EPF has no driver

   - Add kernel-doc for pci_epc_raise_irq() and pci_epc_map_msi_irq()
     MSI vector parameters

   - Pass EPF device ID to driver probe functions

   - Return -EALREADY if EPC has already been started/stopped

   - Add linkdown notifier support and use it in qcom-ep

   - Add Bus Master Enable event support and use it in qcom-ep

   - Add Qualcomm Modem Host Interface (MHI) endpoint driver

   - Add Layerscape PME interrupt handling to manage link-up
     notification

  Cadence PCIe controller driver:

   - Wait for link retrain to complete when working around the J721E
     i2085 erratum with Gen2 mode

  Faraday FTPC100 PCI controller driver:

   - Release clock resources on error paths

  Freescale i.MX6 PCIe controller driver:

   - Save and restore Root Port MSI control to work around hardware defect

  Intel VMD host bridge driver:

   - Reset VMD config register between soft reboots

   - Capture pci_reset_bus() return value instead of printing junk when
     it fails

  Qualcomm PCIe controller driver:

   - Add SDX65 endpoint compatible string to DT binding

   - Disable register write access after init for IP v2.3.3, v2.9.0

   - Use DWC helpers for enabling/disabling writes to DBI registers

   - Hide slot hotplug capability for IP v1.0.0, v1.9.0, v2.1.0, v2.3.2,
     v2.3.3, v2.7.0, v2.9.0

   - Reuse v2.3.2 post-init sequence for v2.4.0

  Renesas R-Car PCIe controller driver:

   - Remove unused static pcie_base and pcie_dev

  Rockchip PCIe controller driver:

   - Remove writes to unused registers

   - Write endpoint Device ID using correct register

   - Assert PCI Configuration Enable bit after probe so endpoint
     responds instead of generating Request Retry Status messages

   - Poll waiting for PHY PLLs to lock

   - Update RK3399 example DT binding to be valid

   - Use RK3399 PCIE_CLIENT_LEGACY_INT_CTRL to generate INTx instead of
     manually generating PCIe message

   - Use multiple windows to avoid address translation conflicts

   - Use u32 (not u16) when accessing 32-bit registers

   - Hide MSI-X Capability, since RK3399 can't generate MSI-X

   - Set endpoint controller required alignment to 256

  Synopsys DesignWare PCIe controller driver:

   - Wait for link to come up only if we've initiated link training

  Miscellaneous:

   - Add pci_clear_master() stub for non-CONFIG_PCI"

6c1561fb90 ARM: SoC devicetree updates for 6.5
The biggest change this time is for the 32-bit devicetree files, which
 are all moved to a new location, using separate subdirectories for each
 SoC vendor, following the same scheme that is used on arm64, mips and
 riscv. This has been discussed for many years, but so far we never did
 this as there was a plan to move the files out of the kernel entirely,
 which has never happened.
 
 The impact of this will be that all external patches no longer apply,
 and anything depending on the location of the dtb files in the build
 directory will have to change. The installed files after 'make
 dtbs_install' keep the current location.
 
 There are six added SoCs here that are largely variants of previously
 added chips. Two other chips are added in a separate branch along
 with their device drivers.
 
 * The Samsung Exynos 4212 makes its return after the Samsung Galaxy
   Express phone is addded at last. The SoC support was originally
   added in 2012 but removed again in 2017 as it was unused at the time.
 
 * Amlogic C3 is a Cortex-A35 based smart IP camera chip
 
 * Qualcomm MSM8939 (Snapdragon 615) is a more featureful variant of
   the still common MSM8916 (Snapdragon 410) phone chip that has been
   supported for a long time.
 
 * Qualcomm SC8180x (Snapdragon 8cx) is one of their earlier high-end
   laptop chips, used in the Lenovo Flex 5G, which is added along with
   the reference board.
 
 * Qualcomm SDX75 is the latest generation modem chip that is used
   as a peripherial in phones but can also run a standalone Linux.  Unlike
   the prior 32-bit SDX65 and SDX55, this now has a 64-bit Cortex-A55.
 
 * Alibaba T-Head TH1520 is a quad-core RISC-V chip based on the Xuantie
   C910 core, a step up from all previously added rv64 chips.
 
 All of the above come with reference board implementations, those included
 there are 39 new board files, but only five more 32-bit this time, probably
 a new low:
 
 * Marantec Maveo board based on dhcor imx6ull module
 
 * Endian 4i Edge 200, based on the armv5 Marvell Kirkwood chip
 
 * Epson Moverio BT-200 AR glasses based on TI OMAP4
 
 * PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM
 
 * ICnova ADB4006 board based on Allwinner A20
 
 On the 64-bit side, there are also fewer addded machines than
 we had in the recent releases:
 
 * Three boards based on NXP i.MX8: Emtop SoM & Baseboard,
   NXP i.MX8MM EVKB board and i.MX8MP based Gateworks Venice
   gw7905-2x device.
 
 * NVIDIA IGX Orin and Jetson Orin Nano boards, both based on
   tegra234
 
 * Qualcomm gains support for 6 reference boards on various members
   of their IPQ networking SoC series, as well as the Sony Xperia M4
   Aqua phone, the Acer Aspire 1 laptop, and the Fxtec Pro1X board
   on top of the various reference platforms for their new chips.

Merge tag 'soc-dt-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC devicetree updates from Arnd Bergmann:
 "The biggest change this time is for the 32-bit devicetree files, which
  are all moved to a new location, using separate subdirectories for
  each SoC vendor, following the same scheme that is used on arm64, mips
  and riscv. This has been discussed for many years, but so far we never
  did this as there was a plan to move the files out of the kernel
  entirely, which has never happened.

  The impact of this will be that all external patches no longer apply,
  and anything depending on the location of the dtb files in the build
  directory will have to change. The installed files after 'make
  dtbs_install' keep the current location.

  There are six added SoCs here that are largely variants of previously
  added chips. Two other chips are added in a separate branch along with
  their device drivers.

   - The Samsung Exynos 4212 makes its return after the Samsung Galaxy
     Express phone is addded at last. The SoC support was originally
     added in 2012 but removed again in 2017 as it was unused at the
     time.

   - Amlogic C3 is a Cortex-A35 based smart IP camera chip

   - Qualcomm MSM8939 (Snapdragon 615) is a more featureful variant of
     the still common MSM8916 (Snapdragon 410) phone chip that has been
     supported for a long time.

   - Qualcomm SC8180x (Snapdragon 8cx) is one of their earlier high-end
     laptop chips, used in the Lenovo Flex 5G, which is added along with
     the reference board.

   - Qualcomm SDX75 is the latest generation modem chip that is used as
     a peripherial in phones but can also run a standalone Linux. Unlike
     the prior 32-bit SDX65 and SDX55, this now has a 64-bit Cortex-A55.

   - Alibaba T-Head TH1520 is a quad-core RISC-V chip based on the
     Xuantie C910 core, a step up from all previously added rv64 chips.

  All of the above come with reference board implementations, those
  included there are 39 new board files, but only five more 32-bit this
  time, probably a new low:

   - Marantec Maveo board based on dhcor imx6ull module

   - Endian 4i Edge 200, based on the armv5 Marvell Kirkwood chip

   - Epson Moverio BT-200 AR glasses based on TI OMAP4

   - PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM

   - ICnova ADB4006 board based on Allwinner A20

  On the 64-bit side, there are also fewer addded machines than we had
  in the recent releases:

   - Three boards based on NXP i.MX8: Emtop SoM & Baseboard, NXP i.MX8MM
     EVKB board and i.MX8MP based Gateworks Venice gw7905-2x device.

   - NVIDIA IGX Orin and Jetson Orin Nano boards, both based on tegra234

   - Qualcomm gains support for 6 reference boards on various members of
     their IPQ networking SoC series, as well as the Sony Xperia M4 Aqua
     phone, the Acer Aspire 1 laptop, and the Fxtec Pro1X board on top
     of the various reference platforms for their new chips.

   - Rockchips support for several newer boards: Indiedroid Nova
     (rk3588), Edgeble Neural Compute Module 6B (rk3588), FriendlyARM
     NanoPi R2C Plus (rk3328), Anbernic RG353PS (rk3566), Lunzn
     Fastrhino R66S/R68S (rk3568)

   - TI K3/AM625 based PHYTEC phyBOARD-Lyra-AM625 board and Toradex
     Verdin family with AM62 COM, carrier and dev boards

  Other changes to existing boards contain the usual minor improvements
  along with

   - continued updates to clean up dts files based on dtc warnings and
     binding checks, in particular cache properties and node names

   - support for devicetree overlays on at91, bcm283x

8bbec86ce6 dt-bindings: PCI: fsl,imx6q: fix assigned-clocks warning
assigned-clocks are a dependency of clocks, however the dtschema has
limitation and expects clocks to be present in the binding using
assigned-clocks, not in other referenced bindings.  The clocks were
defined in common fsl,imx6q-pcie-common.yaml, which is referenced by
fsl,imx6q-pcie-ep.yaml.  The fsl,imx6q-pcie-ep.yaml used assigned-clocks
thus leading to warnings:

  Documentation/devicetree/bindings/pci/fsl,imx6q-pcie-ep.example.dtb: pcie-ep@33800000:
    Unevaluated properties are not allowed ('assigned-clock-parents', 'assigned-clock-rates', 'assigned-clocks' were unexpected)
  From schema: Documentation/devicetree/bindings/pci/fsl,imx6q-pcie-ep.yaml

Fix this by moving clocks to each specific schema from the common one
and narrowing them to strictly match what is expected for given device.

Pull pci updates from Bjorn Helgaas:
 "Resource management:

   - Add pci_dev_for_each_resource() and pci_bus_for_each_resource()
     iterators

  PCIe native device hotplug:

   - Fix AB-BA deadlock between reset_lock and device_lock

  Power management:

   - Wait longer for devices to become ready after resume (as we do for
     reset) to accommodate Intel Titan Ridge xHCI devices

   - Extend D3hot delay for NVIDIA HDA controllers to avoid
     unrecoverable devices after a bus reset

  Error handling:

   - Clear PCIe Device Status after EDR since generic error recovery now
     only clears it when AER is native

  ASPM:

   - Work around Chromebook firmware defect that clobbers Capability
     list (including ASPM L1 PM Substates Cap) when returning from
     D3cold to D0

  Freescale i.MX6 PCIe controller driver:

c025c7e5db dt-bindings: PCI: qcom: Document msi-map and msi-map-mask properties
The Qcom PCIe controller is capable of using either internal MSI controller
or the external GIC-ITS for signaling MSIs sent by endpoint devices.
Currently, the binding only documents the internal MSI implementation.

Let's document the GIC-ITS imeplementation by making use of msi-map and
msi-map-mask properties. Only one of the implementation should be used
at a time and the drivers can choose the preferred one.

Merge tag 'pci-v6.3-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Rework portdrv shutdown so it disables interrupts but doesn't
     disable bus mastering, which leads to hangs on Loongson LS7A

   - Add mechanism to prevent Max_Read_Request_Size (MRRS) increases,
     again to avoid hardware issues on Loongson LS7A (and likely other
     devices based on DesignWare IP)

   - Ignore devices with a firmware (DT or ACPI) node that says the
     device is disabled

  Resource management:

   - Distribute spare resources to unconfigured hotplug bridges at
     boot-time (not just when hot-adding such a bridge), which makes
     hot-adding devices to docks work better. Tried this in v6.1 but had
     to revert for regressions, so try again

   - Fix root bus issue that dropped resources that happened to end
     at 0, e.g., [bus 00]

  PCI device hotplug:

   - Remove device locking when marking device as disconnected so this
     doesn't have to wait for concurrent driver bind/unbind to complete

   - Quirk more Qualcomm bridges that don't fully implement the PCIe
     Slot Status 'Command Completed' bit

  Power management:

   - Account for _S0W of the target bridge in acpi_pci_bridge_d3() so we
     don't miss hot-add notifications for USB4 docks, Thunderbolt, etc

  Reset:

   - Observe delay after reset, e.g., resuming from system sleep,
     regardless of whether a bridge can suspend to D3cold at runtime

   - Wait for secondary bus to become ready after a bridge reset

  Virtualization:

   - Avoid FLR on some AMD FCH AHCI adapters where it doesn't work

   - Allow independent IOMMU groups for some Wangxun NICs that prevent
     peer-to-peer transactions but don't advertise an ACS Capability

  Error handling:

   - Configure End-to-End-CRC (ECRC) only if Linux owns the AER
     Capability

   - Remove redundant Device Control Error Reporting Enable in the AER
     service driver since this is already done for all devices during
     enumeration

  ASPM:

   - Add pci_enable_link_state() interface to allow drivers to enable
     ASPM link state

  Endpoint framework:

   - Move dra7xx and tegra194 linkup processing from hard IRQ to
     threaded IRQ handler

   - Add a separate lock for endpoint controller list of endpoint
     function drivers to prevent deadlock in callbacks

   - Pass events from endpoint controller to endpoint function drivers
     via callbacks instead of notifiers

  Synopsys DesignWare eDMA controller driver (acked by Vinod):

   - Fix CPU vs PCI address issues

   - Fix source vs destination address issues

   - Fix issues with interleaved transfer semantics

   - Fix channel count initialization issue (issue still exists in
     several other drivers)

   - Clean up and improve debugfs usage so it will work on platforms
     with several eDMA devices

  Baikal T-1 PCIe controller driver:

   - Set a 64-bit DMA mask

  Freescale i.MX6 PCIe controller driver:

   - Add i.MX8MM, i.MX8MQ, i.MX8MP endpoint mode DT binding and driver
     support

  Intel VMD host bridge driver:

   - Add quirk to configure PCIe ASPM and LTR. This is normally done by
     BIOS, and will be for future products

  Marvell MVEBU PCIe controller driver:

   - Mark this driver as broken in Kconfig since bugs prevent its daily
     usage

  MediaTek MT7621 PCIe controller driver:

   - Delay PHY port initialization to improve boot reliability for ZBT
     WE1326, ZBT WF3526-P, and some Netgear models

  Qualcomm PCIe controller driver:

   - Add MSM8998 DT compatible string

   - Unify MSM8996 and MSM8998 clock orderings

   - Add SM8350 DT binding and driver support

   - Add IPQ8074 Gen3 DT binding and driver support

   - Correct qcom,perst-regs in DT binding

     regulators and clocks are disabled on late host-init errors

  Socionext UniPhier Pro5 controller driver:

   - Clean up uniphier-ep reg, clocks, resets, and their names in DT
     binding

  Synopsys DesignWare PCIe controller driver:

   - Restrict coherent DMA mask to 32 bits for MSI, but allow controller
     drivers to set 64-bit streaming DMA mask

   - Add eDMA engine support in both Root Port and Endpoint controllers

  Miscellaneous:

   - Remove MODULE_LICENSE from boolean drivers so they don't look like
     modules so modprobe can complain about them"

89a7adad3c dt-bindings: PCI: qcom: Add SM8350
Add bindings for two PCIe hosts on SM8350 platform. The only difference
between them is in the aggre0 clock, which warrants the oneOf clause for
the clocks properties.

resets, and their names that can be taken by the compatible string.

The order of their names doesn't change here.
