Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Print the actual delay time in pci_bridge_wait_for_secondary_bus()
instead of assuming it was 1000ms (Wilfred Mallawa)
- Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
devices', which broke resume from system sleep on AMD platforms and
has been fixed by other commits (Lukas Wunner)
Resource management:
- Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
and unnecessary (Philipp Stanner)
- Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
and related flags since all uses have been removed (Philipp
Stanner)
- Rework devres 'request' functions so they are no longer 'hybrid',
i.e., their behavior no longer depends on whether
pcim_enable_device or pci_enable_device() was used, and remove
related code (Philipp Stanner)
- Warn (not BUG()) about failure to assign optional resources (Ilpo
Järvinen)
Error handling:
- Log the DPC Error Source ID only when it's actually valid (when
ERR_FATAL or ERR_NONFATAL was received from a downstream device)
and decode into bus/device/function (Bjorn Helgaas)
- Determine AER log level once and save it so all related messages
use the same level (Karolina Stolarek)
- Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
Errors (Karolina Stolarek)
- Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
controls on interval and burst count, to avoid flooding logs and
RCU stall warnings (Jon Pan-Doh)
Power management:
- Increment PM usage counter when probing reset methods so we don't
try to read config space of a powered-off device (Alex Williamson)
- Set all devices to D0 during enumeration to ensure ACPI opregion is
connected via _REG (Mario Limonciello)
Power control:
- Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
the filename paths. Retain old deprecated symbols for
compatibility, except for the pwrctrl slot driver
(PCI_PWRCTRL_SLOT) (Johan Hovold)
- When unregistering pwrctrl, cancel outstanding rescan work before
cleaning up data structures to avoid use-after-free issues (Brian
Norris)
Bandwidth control:
- Simplify link bandwidth controller by replacing the count of Link
Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
flag (Ilpo Järvinen)
- Update the Link Speed after retraining, since the Link Speed may
have changed (Ilpo Järvinen)
PCIe native device hotplug:
- Ignore Presence Detect Changed caused by DPC.
pciehp already ignores Link Down/Up events caused by DPC, but on
slots using in-band presence detect, DPC causes a spurious Presence
Detect Changed event (Lukas Wunner)
- Ignore Link Down/Up caused by Secondary Bus Reset.
On hotplug ports using in-band presence detect, the reset causes a
Presence Detect Changed event, which mistakenly caused teardown and
re-enumeration of the device. Drivers may need to annotate code
that resets their device (Lukas Wunner)
Virtualization:
- Add an ACS quirk for Loongson Root Ports that don't advertise ACS
but don't allow peer-to-peer transactions between Root Ports; the
quirk allows each Root Port to be in a separate IOMMU group (Huacai
Chen)
Endpoint framework:
- For fixed-size BARs, retain both the actual size and the possibly
larger size allocated to accommodate iATU alignment requirements
(Jerome Brunet)
- Simplify ctrl/SPAD space allocation and avoid allocating more space
than needed (Jerome Brunet)
- Correct MSI-X PBA offset calculations for DesignWare and Cadence
endpoint controllers (Niklas Cassel)
- Align the return value (number of interrupts) encoding for
pci_epc_get_msi()/pci_epc_ops::get_msi() and
pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)
- Align the nr_irqs parameter encoding for
pci_epc_set_msi()/pci_epc_ops::set_msi() and
pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)
Common host controller library:
- Convert pci-host-common to a library so platforms that don't need
native host controller drivers don't need to include these helper
functions (Manivannan Sadhasivam)
Apple PCIe controller driver:
- Extract ECAM bridge creation helper from pci_host_common_probe() to
separate driver-specific things like MSI from PCI things (Marc
Zyngier)
- Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
varying capabilities (Marc Zyngier)
- Skip ports disabled in DT when setting up ports (Janne Grunau)
- Add t6020 compatible string (Alyssa Rosenzweig)
- Add T602x PCIe support (Hector Martin)
- Directly set/clear INTx mask bits because T602x dropped the
accessors that could do this without locking (Marc Zyngier)
- Move port PHY registers to their own reg items to accommodate
T602x, which moves them around; retain default offsets for existing
DTs that lack phy%d entries with the reg offsets (Hector Martin)
- Stop polling for core refclk, which doesn't work on T602x and the
bootloader has already done anyway (Hector Martin)
- Use gpiod_set_value_cansleep() when asserting PERST# in probe
because we're allowed to sleep there (Hector Martin)
Cadence PCIe controller driver:
- Drop a runtime PM 'put' to resolve a runtime atomic count underflow
(Hans Zhang)
- Make the cadence core buildable as a module (Kishon Vijay Abraham I)
- Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
loadable drivers when they are removed (Siddharth Vadapalli)
Freescale i.MX6 PCIe controller driver:
- Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
(Richard Zhu)
- Remove redundant dw_pcie_wait_for_link() from
imx_pcie_start_link(); since the DWC core does this, imx6 only
needs it when retraining for a faster link speed (Richard Zhu)
- Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)
- Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
some cases, the controller can't exit 'L23 Ready' through Beacon or
PERST# deassertion (Richard Zhu)
- Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
GT/s, causing timeouts in L1 (Richard Zhu)
- Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)
- Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)
Mobiveil PCIe controller driver:
- Return bool (not int) for link-up check in
mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
Zhang)
NVIDIA Tegra194 PCIe controller driver:
- Create debugfs directory for 'aspm_state_cnt' only when
CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
Zhang)
Qualcomm PCIe controller driver:
- Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
equalization presets (Krishna Chaitanya Chundru)
- Read Maximum Link Width from the Link Capabilities register if DT
lacks 'num-lanes' property (Krishna Chaitanya Chundru)
- Add Physical Layer 64 GT/s Capability ID and register offsets for
8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
Chundru)
- Add generic dwc support for configuring lane equalization presets
(Krishna Chaitanya Chundru)
- Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)
Renesas R-Car PCIe controller driver:
- Describe endpoint BAR 4 as being fixed size (Jerome Brunet)
- Document how to obtain R-Car V4H (r8a779g0) controller firmware
(Yoshihiro Shimoda)
Rockchip PCIe controller driver:
- Reorder rockchip_pci_core_rsts because
reset_control_bulk_deassert() deasserts in reverse order, to fix a
link training regression (Jensen Huang)
- Mark RK3399 as being capable of raising INTx interrupts (Niklas
Cassel)
Rockchip DesignWare PCIe controller driver:
- Check only PCIE_LINKUP, not LTSSM status, to determine whether the
link is up (Shawn Lin)
- Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
for Root Complex and Endpoint modes (Shawn Lin)
- Hide the broken ATS Capability in rockchip_pcie_ep_init() instead
of rockchip_pcie_ep_pre_init() so it stays hidden after PERST#
resets non-sticky registers (Shawn Lin)
- Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
(Diederik de Haas)
Synopsys DesignWare PCIe controller driver:
- Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training
more robust; this will not affect the intended link width if all
lanes are functional (Wenbin Yao)
- Return bool (not int) for link-up check in dw_pcie_ops.link_up()
and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay,
keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx,
tegra194, uniphier, visconti (Hans Zhang)
- Add debugfs support for exposing DWC device-specific PTM context
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Make j721e buildable as a loadable and removable module (Siddharth
Vadapalli)
- Fix j721e host/endpoint dependencies that result in link failures
in some configs (Arnd Bergmann)

link-specific events) for ipq8074, ipq8074-gen3, ipq6018, sa8775p,
sc7280, sc8180x sdm845, sm8150, sm8250, sm8350 (Manivannan
Sadhasivam)

and IPQ9574 (Varadarajan Narayanan)
- Convert v3,v360epc-pci from text to DT schema binding (Rob Herring)
- Change microchip,pcie-host DT binding to be 'dma-noncoherent' since
PolarFire may be configured that way (Conor Dooley)
Miscellaneous:
- Drop 'pci' suffix from intel_mid_pci.c filename to match similar
files (Andy Shevchenko)
- All platforms with PCI have an MMU, so add PCI Kconfig dependency
on MMU to simplify build testing and avoid inadvertent build
regressions (Arnd Bergmann)

Pull IPMI updates from Corey Minyard:
"Restructure the IPMI driver.
This is a restructure of the IPMI driver, mostly to remove SRCU. The
locking had issues, and they were not going to be straightforward to
fix. Plus it used tons of memory and was generally a pain.
Most of this moves handling of messages out of bh and interrupt
context and runs it in thread context. Then getting rid of SRCU is
easy.
This also has a minor cleanup to remove a warning on newer GCCs and to
fix some documentation"

Pull gpio updates from Bartosz Golaszewski:
"We have three new drivers, some refactoring in the GPIO core, lots of
various changes across many drivers, new configfs interface for the
virtual gpio-aggregator module and DT-bindings updates.
The treewide conversion of GPIO drivers to using the new value setter
callbacks is ongoing with another round of GPIO drivers updated. You
will also see these commits coming in from other subsystems as with
the relevant changes merged into mainline last cycle, I've started
converting GPIO providers located elsewhere than drivers/gpio/.
GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where
applicable which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which
will take off the burden from GPIO drivers of checking this down
the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter
callbacks
- convert more drivers to making the irq_chip immutable as is
recommended by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built
with COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that
makes the setup easier for user-space than the existing
driver-level sysfs attributes and also adds more advanced
configuration features (such as referring to aggregated lines by
their original names or modifying their names as exposed by the
aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the
global GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x

Pull documentation updates from Jonathan Corbet:
"A moderately busy cycle for documentation this time around:
- The most significant change is the replacement of the old
kernel-doc script (a monstrous collection of Perl regexes that
predates the Git era) with a Python reimplementation. That, too, is
a horrifying collection of regexes, but in a much cleaner and more
maintainable structure that integrates far better with the Sphinx
build system.
This change has been in linux-next for the full 6.15 cycle; the
small number of problems that turned up have been addressed,
seemingly to everybody's satisfaction. The Perl kernel-doc script
remains in tree (as scripts/kernel-doc.pl) and can be used with a
command-line option if need be. Unless some reason to keep it
around materializes, it will probably go away in 6.17.
Credit goes to Mauro Carvalho Chehab for doing all this work.
- Some RTLA documentation updates
- A handful of Chinese translations
- The usual collection of typo fixes, general updates, etc"

Board files are deprecated by DT, and the last user of
nvmem_add_cell_table() was removed by commit 2af4fcc0d3574482 ("ARM:
davinci: remove unused board support") in v6.3. Hence remove all
support for nvmem cell tables, and update the documentation.
Device drivers can still register a single cell using
nvmem_add_one_cell() (which was not documented before).

pmem.c regs.c mbox.c identifiers were missing. Add them to
memory-devices.rst following their respective DOC comment includes.
Two acpi.c identifiers were available, but not used in kernel-doc's:
1) Add add_cxl_resources to memory-devices.rst and fix up the Sphinx
complaint on the ascii art by escaping it.
2) Add cxl_acpi_evaluate_qtg_dsm to access-coordinates.rst.
core/features.c is new. Add a "DOC: cxl features" comment to the
