Merge tag 'pci-v7.3-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
"Resource management:

- Add hotplug reservation only once (not at each level of the
hierarchy) so bridge windows don't grow more than necessary (Ilpo
Järvinen)

Driver binding:

- Rework device matching so device ID lifetime only needs to cover
the probe path since dynamic IDs can be removed at any time (Gary
Guo)

Error handling:

- Update mappings of AER errors to agent & layer and log them for
each individual error when multiple errors detected (Lukas Wunner)

- Log Error Source only once, not twice in separate messages (Lukas
Wunner)

- Emit TLP Log only for unmasked errors (Lukas Wunner)

- Support Advisory Non-Fatal Errors (Lukas Wunner)

- Allow DPC on all Downstream Ports, not just Root Ports, when OS
controls AER (Darshit Shah)

ASPM:

- Program the same ASPM Control values for every function of
multi-function devices, as recommended by the PCIe spec (Krishna
Chaitanya Chundru)

- Avoid L0s for Realtek RTS525A, where it causes an AER interrupt
storm (Max Lee)

- Avoid ASPM L0s, L1, and L1 PM Substates based on 'aspm-no-l0s',
'aspm-no-l1' [1], and 'aspm-no-l1ss' DT properties (Krishna
Chaitanya Chundru)

Power management:

- Allow D3 for native hotplug-capable Root Ports on non-x86 platforms
(we avoid D3 for these ports on x86 because some old platforms
didn't validate it) (Manivannan Sadhasivam)

- Allow portdrv to claim Ports even if they don't support services
(AER, PME, DPC, hotplug, etc) so it can do power management (Brian
Norris)

Power control:

- Add support for PCIe WAKE# interrupt when described via DT (Krishna
Chaitanya Chundru)

- For the TC9563 PCIe switch:

- Take a reference on the I2C adapter to avoid uninterruptible
hang when unloading an I2C module while in-use (Johan Hovold)

- Update DT binding and driver to restrict Tx Amplitude, DFE and
N_FTS to USP, DSP1 and DSP2 (Manivannan Sadhasivam)

- Power off only external-facing ports (DSP1, DSP2), leaving USP
and DSP3 (aka VDSP) powered up (Manivannan Sadhasivam)

- Move integrated MAC Endpoint out of the list of internal ports
and configure it separately (Manivannan Sadhasivam)

Virtualization:

- Add ACS quirk for Pericom PI7C9X2G608 switches (Tim Harvey)

- Fix a long-standing bug in the Intel PCH Root Port MPC ACS quirk
that didn't update the intended INTEL_MPC_REG_IRBNCE bit because it
used a 16-bit config write when a 32-bit write was intended
(Mohamad Raizudeen)

Procfs:

- Avoid spurious runtime PM wakeup on config space accesses that are
outside config space and fail before reaching PCI (Krzysztof
Wilczyński)

- Warn on user-space writes to kernel-exclusive config space regions,
as we already do for sysfs (Krzysztof Wilczyński)

- Check credentials of opener, not reader, for config space reads, as
we already do for sysfs (Krzysztof Wilczyński)

Sysfs:

- In pci_write_legacy_io(), avoid out-of-bounds reads from the user
buffer and fix incorrect ioport write data (1-byte writes on
little-endian powerpc, 2- and 4-byte writes on big-endian powerpc)
(Krzysztof Wilczyński)

- In pci_read_legacy_io(), fix incorrect ioport read data for 2- and
4-byte reads on big-endian powerpc (Krzysztof Wilczyński)

- Fix I/O port accessor argument order in Alpha pci_legacy_write()
(Krzysztof Wilczyński)

- Avoid spurious runtime PM wakeup on config space accesses that are
outside config space and fail before reaching PCI (Krzysztof
Wilczyński)

- Return -EINVAL, not -ENODEV, for mmap of I/O BAR that fails because
the arch doesn't support it, as we do for procfs (Krzysztof
Wilczyński)

- Check for LOCKDOWN_PCI_ACCESS for legacy_io and legacy_mem, as we
do for other config space accessors (Krzysztof Wilczyński)

Peer-to-peer DMA:

of defining driver-private duplicates (Thierry Reding)

Generic host bridge driver:

- Fix NULL pointer dereference that caused enumeration failures on
32-bit CAM systems (Steffen Persvold)

Amlogic Meson PCIe controller driver:

- Correct the PERST# GPIO state so it remains asserted until power
and REFCLK become stable to fix enumeration failure (Ronald
Claveau)

ASPEED PCIe controller driver:

the host bridge (Sherry Sun)

- Fix build issues when PCI_PWRCTRL_GENERIC or PCI_HOST_COMMON is a
module (Arnd Bergmann)

- Create pwrctrl devices only once by doing it from imx_pcie_probe()
instead of imx_pcie_host_init(), which is used during both probe
and resume (Sherry Sun)

during suspend to preserve wakeup capability (Sherry Sun)

- Add runtime PM support for i.MX95 to allow dynamic power management
when the link is idle (Richard Zhu)

Intel VMD host bridge driver:

- Support device ID 0x28C1 and assume that BIOS has already
enumerated the hierarchy below VMD and stored bus range info for OS
to use (Nirmal Patel)

- Add support for VMCONFIG BUS_RESTRICT_CFG=3, which makes it
possible to enumerate downstream devices on Intel Arrow Lake-HX
systems and probably others (Ali Alaei)

- Add missing MODULE_DEVICE_TABLE() to generate module alias info for
OF-based module autoloading (Pengpeng Hou)

StarFive PCIe controller driver:

- Fix resource leaks on error paths in host_init() (Ali Tariq)

- Fix runtime PM handling and teardown ordering to avoid register
access while power or clocks are disabled (Ali Tariq)

- Check for runtime PM resume failure to avoid register access while
power or clocks are disabled (Ali Tariq)

Synopsys DesignWare PCIe controller driver:

- Add LECARC PMU IDs to the DWC RAS/DES VSEC list so it can take
advantage of the existing debugfs support for silicon debug, error
injection, and event counters (Brett Zhou)

- Factor pcie_valid_speed() and pci_bus_speed2lnkctl2() out of bwctrl
so they can be shared by the DWC core (Hans Zhang)

- Flush MSI writes from endpoint before unmapping the iATU, as we
already do for MSI-X writes (Niklas Cassel)

- Unmap MSI iATU window before mapping MSI-X window, to avoid a
subsequent MSI write using a disabled aperture and losing the
interrupt (Niklas Cassel)

- Change endpoint .pre_init() and .init() callbacks to return errors
and handle them (Marek Vasut)

UltraRISC PCIe controller driver:

- Add 'core', 'dbi', and 'aux' clocks to DT binding and manage them
in the driver (Jia Wang)

PCI: cadence: Fix host/endpoint dependencies for cadence-plat driver

The cadence-plat driver has a single platform driver that can be built-in
or a loadable module, but it calls two separate backend drivers depending
on whether it is a host or endpoint.

If one of the mode is build as built-in and another as loadable module,
we end up with a situation where the built-in pcie-cadence-plat driver
tries to call the modular host or endpoint driver, which causes a link
failure:

ld: error: undefined symbol: cdns_pcie_ep_setup
>>> referenced by pcie-cadence-plat.c
>>> drivers/pci/controller/cadence/pcie-cadence-plat.o:(cdns_plat_pcie_probe) in archive vmlinux.a

ld: error: undefined symbol: cdns_pcie_host_setup
>>> referenced by pcie-cadence-plat.c
>>> drivers/pci/controller/cadence/pcie-cadence-plat.o:(cdns_plat_pcie_probe) in archive vmlinux.a

Fix this by moving the 'select' of PCIE_CADENCE_HOST and PCIE_CADENCE_EP
from the individual PLAT_HOST/PLAT_EP symbols into the common PCIE_CADENCE_PLAT
symbol, conditioned on which backends (modes) are enabled.

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:

driver to support both (Manivannan Sadhasivam)

Apple PCIe controller driver:

- Move struct pci_host_bridge allocation from pci_host_common_init()
to callers, which significantly simplifies pcie-apple (Marc
Zyngier)

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

- 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)"
