Merge tag 'pci-v7.0-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
"Enumeration:

- Don't try to enable Extended Tags on VFs since that bit is Reserved
and causes misleading log messages (Håkon Bugge)

- Initialize Endpoint Read Completion Boundary to match Root Port,
regardless of ACPI _HPX (Håkon Bugge)

- Apply _HPX PCIe Setting Record only to AER configuration, and only
when OS owns PCIe hotplug but not AER, to avoid clobbering Extended
Tag and Relaxed Ordering settings (Håkon Bugge)

Resource management:

- Move CardBus code to setup-cardbus.c and only build it when
CONFIG_CARDBUS is set (Ilpo Järvinen)

- Fix bridge window alignment with optional resources, where
additional alignment requirement was previously lost (Ilpo
Järvinen)

- Stop over-estimating bridge window size since they are now assigned
without any gaps between them (Ilpo Järvinen)

- Increase resource MAX_IORES_LEVEL to avoid /proc/iomem flattening
for nested bridges and endpoints (Ilpo Järvinen)

- Add pbus_mem_size_optional() to handle sizes of optional resources
(SR-IOV VF BARs, expansion ROMs, bridge windows) (Ilpo Järvinen)

- Don't claim disabled bridge windows to avoid spurious claim
failures (Ilpo Järvinen)

Driver binding:

- Fix device reference leak in pcie_port_remove_service() (Uwe
Kleine-König)

- Move pcie_port_bus_match() and pcie_port_bus_type to PCIe-specific
portdrv.c (Uwe Kleine-König)

- Convert portdrv to use pcie_port_bus_type.probe() and .remove()
callbacks so .probe() and .remove() can eventually be removed from
struct device_driver (Uwe Kleine-König)

Error handling:

- Clear stale errors on reporting agents upon probe so they don't
look like recent errors (Lukas Wunner)

- Add generic RAS tracepoint for hotplug events (Shuai Xue)

- Add RAS tracepoint for link speed changes (Shuai Xue)

Power management:

- Avoid redundant delay on transition from D3hot to D3cold if the
device was already in D3hot (Brian Norris)

- Prevent runtime suspend until devices are fully initialized to
avoid saving incompletely configured device state (Brian Norris)

Power control:

- Add power_on/off callbacks with generic signature to pwrseq,
tc9563, and slot drivers so they can be used by pwrctrl core
(Manivannan Sadhasivam)

- Add PCIe M.2 connector support to the slot pwrctrl driver
(Manivannan Sadhasivam)

- Switch to pwrctrl interfaces to create, destroy, and power on/off
devices, calling them from host controller drivers instead of the
PCI core (Manivannan Sadhasivam)

- Drop qcom .assert_perst() callbacks since this is now done by the
controller driver instead of the pwrctrl driver (Manivannan
Sadhasivam)

Virtualization:

- Remove an incorrect unlock in pci_slot_trylock() error handling
(Jinhui Guo)

- Lock the bridge device for slot reset (Keith Busch)

- Enable ACS after IOMMU configuration on OF platforms so ACS is
enabled an all devices; previously the first device enumerated
(typically a Root Port) didn't have ACS enabled (Manivannan
Sadhasivam)

- Disable ACS Source Validation for IDT 0x80b5 and 0x8090 switches to
work around hardware erratum; previously ACS SV was only
temporarily disabled, which worked for enumeration but not after
reset (Manivannan Sadhasivam)

Peer-to-peer DMA:

- Release per-CPU pgmap ref when vm_insert_page() fails to avoid hang
when removing the PCI device (Hou Tao)

- Remove incorrect p2pmem_alloc_mmap() warning about page refcount
(Hou Tao)

Endpoint framework:

- Add configfs sub-groups synchronously to avoid NULL pointer
dereference when racing with removal (Liu Song)

- Fix swapped parameters in pci_{primary/secondary}_epc_epf_unlink()
functions (Manikanta Maddireddy)

ASPEED PCIe controller driver:

- Add ASPEED Root Complex DT binding and driver (Jacky Chou)

Freescale i.MX6 PCIe controller driver:

- Add DT binding and driver support for an optional external refclock
in addition to the refclock from the internal PLL (Richard Zhu)

- Fix CLKREQ# control so host asserts it during enumeration and
Endpoints can use it afterwards to exit the L1.2 link state
(Richard Zhu)

NVIDIA Tegra PCIe controller driver:

- Export irq_domain_free_irqs() to allow PCI/MSI drivers that tear
down MSI domains to be built as modules (Aaron Kling)

- Allow pci-tegra to be built as a module (Aaron Kling)

NVIDIA Tegra194 PCIe controller driver:

- Relax Kconfig so tegra194 can be built for platforms beyond
Tegra194 (Vidya Sagar)

Qualcomm PCIe controller driver:

- Merge SC8180x DT binding into SM8150 (Krzysztof Kozlowski)

- Move SDX55, SDM845, QCS404, IPQ5018, IPQ6018, IPQ8074 Gen3,
IPQ8074, IPQ4019, IPQ9574, APQ8064, MSM8996, APQ8084 to dedicated
schema (Krzysztof Kozlowski)

- Add DT binding and driver support for SA8255p Endpoint being
configured by firmware (Mrinmay Sarkar)

- Parse PERST# from all PCIe bridge nodes for future platforms that
will have PERST# in Switch Downstream Ports as well as in Root
Ports (Manivannan Sadhasivam)

Renesas RZ/G3S PCIe controller driver:

- Use pci_generic_config_write() since the writability provided by
the custom wrapper is unnecessary (Claudiu Beznea)

SOPHGO PCIe controller driver:

- Disable ASPM L0s and L1 on Sophgo 2044 PCIe Root Ports (Inochi
Amaoto)

Synopsys DesignWare PCIe controller driver:

- Extend PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() to return a
pointer to the preceding Capability, to allow removal of
Capabilities that are advertised but not fully implemented (Qiang
Yu)

- Remove MSI and MSI-X Capabilities in platforms that can't support
them, so the PCI core automatically falls back to INTx (Qiang Yu)

- Add ASPM L1.1 and L1.2 Substates context to debugfs ltssm_status
for drivers that support this (Shawn Lin)

- Skip PME_Turn_Off broadcast and L2/L3 transition during suspend if
link is not up to avoid an unnecessary timeout (Manivannan
Sadhasivam)

- Revert dw-rockchip, qcom, and DWC core changes that used link-up
IRQs to trigger enumeration instead of waiting for link to be up
because the PCI core doesn't allocate bus number space for
hierarchies that might be attached (Niklas Cassel)

- Make endpoint iATU entry for MSI permanent instead of programming
it dynamically, which is slow and racy with respect to other
concurrent traffic, e.g., eDMA (Koichiro Den)

- Use iMSI-RX MSI target address when possible to fix endpoints using
32-bit MSI (Shawn Lin)

- Allow DWC host controller driver probe to continue if device is not
found or found but inactive; only fail when there's an error with
the link (Manivannan Sadhasivam)

- For controllers like NXP i.MX6QP and i.MX7D, where LTSSM registers
are not accessible after PME_Turn_Off, simply wait 10ms instead of
polling for L2/L3 Ready (Richard Zhu)

- Use multiple iATU entries to map large bridge windows and DMA
ranges when necessary instead of failing (Samuel Holland)

- Add EPC dynamic_inbound_mapping feature bit for Endpoint
Controllers that can update BAR inbound address translation without
requiring EPF driver to clear/reset the BAR first, and advertise it
for DWC-based Endpoints (Koichiro Den)

- Add EPC subrange_mapping feature bit for Endpoint Controllers that
can map multiple independent inbound regions in a single BAR,
implement subrange mapping, advertise it for DWC-based Endpoints,
and add Endpoint selftests for it (Koichiro Den)

- Make resizable BARs work for Endpoint multi-PF configurations;
previously it only worked for PF 0 (Aksh Garg)

- Fix Endpoint non-PF 0 support for BAR configuration, ATU mappings,
and Address Match Mode (Aksh Garg)

- Set up iATU when ECAM is enabled; previously IO and MEM outbound
windows weren't programmed, and ECAM-related iATU entries weren't
restored after suspend/resume, so config accesses failed (Krishna
Chaitanya Chundru)

Miscellaneous:

- Use system_percpu_wq and WQ_PERCPU to explicitly request per-CPU
work so WQ_UNBOUND can eventually be removed (Marco Crivellari)"

PCI: rcar-host: Add OF Kconfig dependency to avoid objtool no-cfi warning

After commit 894af4a1cde6 ("objtool: Validate kCFI calls"), compile
testing pcie-rcar-host.c with CONFIG_FINEIBT=y and CONFIG_OF=n results
in a no-cfi objtool warning in rcar_pcie_probe():

$ cat allno.config
CONFIG_CFI=y
CONFIG_COMPILE_TEST=y
CONFIG_CPU_MITIGATIONS=y
CONFIG_GENERIC_PHY=y
CONFIG_MITIGATION_RETPOLINE=y
CONFIG_MODULES=y
CONFIG_PCI=y
CONFIG_PCI_MSI=y

CONFIG_X86_KERNEL_IBT=y

$ make -skj"$(nproc)" ARCH=x86_64 KCONFIG_ALLCONFIG=1 LLVM=1 clean allnoconfig vmlinux
vmlinux.o: warning: objtool: rcar_pcie_probe+0x191: no-cfi indirect call!

When CONFIG_OF is unset, of_device_get_match_data() returns NULL, so
LLVM knows this indirect call has no valid destination and drops the
kCFI setup before the call, triggering the objtool check that makes sure
all indirect calls have kCFI setup.

This driver depends on OF for probing with non-NULL data for every match
so this call will never be NULL in practice. Add a hard Kconfig
dependency on OF to avoid the warning.

Merge tag 'pci-v6.19-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
"Enumeration:

- Enable host bridge emulation for PCI_DOMAINS_GENERIC platforms (Dan
Williams)

- Switch vmd from custom domain number allocator to the common
allocator to prevent a potential race with new non-VMD buses (Dan
Williams)

- Enable Precision Time Measurement (PTM) only if device advertises
support for a relevant role, to prevent invalid PTM Requests that
cause ACS violations that are reported as AER Uncorrectable
Non-Fatal errors (Mika Westerberg)

Resource management:

- Prevent resource tree corruption when BAR resize fails (Ilpo
Järvinen)

- Restore BARs to the original size if a BAR resize fails (Ilpo
Järvinen)

- Remove BAR release from BAR resize attempts by the xe, i915, and
amdgpu drivers so the PCI core can restore BARs if the resize fails
(Ilpo Järvinen)

- Move Resizable BAR code to rebar.c (Ilpo Järvinen)

- Add pci_rebar_size_supported() and use it in i915 and xe (Ilpo
Järvinen)

- Add pci_rebar_get_max_size() and use it in xe and amdgpu (Ilpo
Järvinen)

Power management and error handling:

- For drivers using PCI legacy suspend, save config state at suspend
so that state (not any earlier state from enumeration, probe, or
error recovery) will be restored when resuming (Lukas Wunner)

- For devices with no driver or a driver that lacks power management,
save config state at hibernate so that state (not any earlier state
from enumeration, probe, or error recovery) will be restored when
resuming (Lukas Wunner)

- Save device config space on device addition, before driver binding,
so error recovery works more reliably (Lukas Wunner)

- Drop pci_save_state() from several drivers that no longer need it
since the PCI core always does it and pci_restore_state() no longer
invalidates the saved state (Lukas Wunner)

- Document use of pci_save_state() by drivers to capture the state
they want restored during error recovery (Lukas Wunner)

Power control:

- Add a struct pci_ops.assert_perst() function pointer to
assert/deassert PCIe PERST# and implement it for the qcom driver
(Krishna Chaitanya Chundru)

- Add DT binding and pwrctrl driver for the Toshiba TC9563 PCIe
switch, which must be held in reset after poweron so the pwrctrl
driver can configure the switch via I2C before bringing up the
links (Krishna Chaitanya Chundru)

Endpoint framework:

- Convert the endpoint doorbell test to use a threaded IRQ to fix a
'sleeping while atomic' issue (Bhanu Seshu Kumar Valluri)

- Add endpoint VNTB MSI doorbell support to reduce latency between
host and endpoint (Frank Li)

Broadcom STB PCIe controller driver:

- Disable advertising ASPM L0s support correctly (Jim Quinlan)

- Add a panic/die handler to print diagnostic info in case PCIe
caused an unrecoverable abort (Jim Quinlan)

Cadence PCIe controller driver:

- Add module support for Cadence platform host and endpoint
controller driver (Manikandan K Pillai)

- Split headers into 'legacy' (LGA) and 'high perf' (HPA) to prepare
for new CIX Sky1 driver (Manikandan K Pillai)

so RPMh votes can account for both (Krishna Chaitanya Chundru)

Rockchip DesignWare PCIe controller driver:

- Add Rockchip RK3528 compatible strings in DT binding (Yao Zi)

STMicroelectronics STM32MP25 PCIe controller driver:

- Fix a race between link training and endpoint register
initialization (Christian Bruel)

- Align endpoint allocations to match the ATU requirements (Christian
Bruel)

Synopsys DesignWare PCIe controller driver:

- Clear L1 PM Substate Capability 'Supported' bits unless glue driver
says it's supported, which prevents users from enabling non-working
L1SS. Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)

- Remove now-superfluous L1SS disable code from tegra194 (Bjorn
Helgaas)

- Configure L1SS support in dw-rockchip when DT says
'supports-clkreq' (Shawn Lin)

TI Keystone PCIe controller driver:

- Fail the probe instead of silently succeeding if ks_pcie_of_data
didn't specify Root Complex or Endpoint mode (Siddharth Vadapalli)

- Make keystone buildable as a loadable module, except on ARM32 where
hook_fault_code() is __init (Siddharth Vadapalli)"

PCI: rcar-gen2: Drop ARM dependency from PCI_RCAR_GEN2

Since the reliance on ARM-specific struct pci_sys_data was removed, this
