The 'msi' child node schema is missing constraints on additional properties.
It turns out it is incomplete and properties for it are documented in the
parent node by mistake. Move the reference to msi-controller.yaml and
the custom properties to the 'msi' node. Adding 'unevaluatedProperties'
ensures all the properties in the 'msi' node are documented.
With the schema corrected, a minimal interrupt controller node is needed
to properly decode the interrupt properties since the example has
multiple interrupt parents.

Drop the unnecessary listing of properties already defined in

The example's indentation is off. While fixing this, the 'bus' node
is unnecessary and can be dropped. It is also preferred to split up
unrelated examples to their own entries.

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

- 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
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

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.

Commit c0aba9f32801 ("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

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.

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

- 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:

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

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
- significant additions to existing SoC support on mediatek,
qualcomm, ti k3 family, starfive jh71xx, NXP i.MX6 and i.MX8, ST
STM32MP1
As usual, a lot more detail is available in the individual merge

Update the example in the documentation to a valid example.
Address for mem-base was invalid, it pointed to address
0x8000'0000 which is the upper region of the DDR which
is not necessarily populated depending on the board.
This address should point to the base of the memory
window region of the controller which is 0xfa00'0000.
Add missing pinctrl.

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.

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.

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

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

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.

MSM8996 and MSM8998 use the same clocks, so use one order to make the
binding simpler.

Instead of "oneOf:" choices, use "allOf:" and "if:" to define reg, clocks,
resets, and their names that can be taken by the compatible string.
The order of their names doesn't change here.

Convert the Rockchip RK3399 PCIe Host/Endpoint controller to DT schema
format. Like most dual mode PCI controllers, we need to split the schema
into common, host and endpoint schemas.
