Effectively all Tesla FSD and Google GS101 DTS patches go via Samsung
SoC maintainer, who applies the same rules as for Samsung SoC: DTS must
be fully DT bindings compliant (`dtbs_check W=1`). Existing sources
already are compliant, so just document that implicit rule by mentioning
respective maintainer profile in their entries.

analog to digital converter. The AD4170-4 design offers a flexible data
acquisition solution with crosspoint multiplexed analog inputs,
configurable ADC voltage reference inputs, ultra-low noise integrated PGA,
digital filtering, wide range of configurable output data rates, internal
oscillator and temperature sensor, four GPIOs, and integrated features for
interfacing with load cell weigh scales, RTD, and thermocouple sensors.
Add basic support for the AD4170-4 ADC with the following features:
- Single-shot read.
- Analog front end PGA configuration.
- Differential and pseudo-differential input configuration.

Merge series from Peng Fan <peng.fan@nxp.com>:
This patchset is a pick up of patch 1,2 from [1]. And I also collect
Linus's R-b for patch 2. After this patchset, there is only one user of
of_gpio.h left in sound driver(pxa2xx-ac97).
of_gpio.h is deprecated, update the driver to use GPIO descriptors.
Patch 1 is to drop legacy platform data which in-tree no users are using it
Patch 2 is to convert to GPIO descriptors
Checking the DTS that use the device, all are using GPIOD_ACTIVE_LOW
polarity for reset-gpios, so all should work as expected with this patch.

Root domains information is somewhat hard to access at runtime. Even
with sched_debug and sched_verbose, such information is only printed
on kernel console when domains are modified.

The UVC driver provides two metadata types V4L2_META_FMT_UVC, and
V4L2_META_FMT_D4XX. The only difference between the two of them is that
V4L2_META_FMT_UVC only copies PTS, SCR, size and flags, and
V4L2_META_FMT_D4XX copies the whole metadata section.
Now we only enable V4L2_META_FMT_D4XX for the Intel D4xx family of
devices, but it is useful to have the whole metadata payload for any
device where vendors include other metadata, such as the one described by
Microsoft:
https://learn.microsoft.com/en-us/windows-hardware/drivers/stream/mf-capture-metadata
This patch introduces a new format V4L2_META_FMT_UVC_MSXU_1_5, that is
identical to V4L2_META_FMT_D4XX.
Let the user enable this format with a quirk for now. This way they can
test if their devices provide useful metadata without rebuilding the
kernel. They can later contribute patches to auto-quirk their devices.
We will also work in methods to auto-detect devices compatible with this
new metadata format.

Microchip Azurite ZL3073x represents chip family providing DPLL
and optionally PHC (PTP) functionality. The chips can be connected
be connected over I2C or SPI bus.
They have the following characteristics:
* up to 5 separate DPLL units (channels)
* 5 synthesizers
* 10 input pins (references)
* 10 outputs
* 20 output pins (output pin pair shares one output)
* Each reference and output can operate in either differential or
single-ended mode (differential mode uses 2 pins)
* Each output is connected to one of the synthesizers
* Each synthesizer is driven by one of the DPLL unit
The device uses 7-bit addresses and 8-bits values. It exposes 8-, 16-,
32- and 48-bits registers in address range <0x000,0x77F>. Due to 7bit
addressing, the range is organized into pages of 128 bytes, with each
page containing a page selector register at address 0x7F.
For reading/writing multi-byte registers, the device supports bulk
transfers.
Add basic functionality to access device registers, probe functionality
both I2C and SPI cases and add devlink support to provide info and
to set clock ID parameter.

Each DPLL channel is used either to provide a pulse-per-clock signal or
to drive an Ethernet equipment clock.
The input and output pins have the following properties:
* label: specifies board label
* connection type: specifies its usage depending on wiring
* list of supported or allowed frequencies: depending on how the pin
is connected and where)
* embedded sync capability: indicates whether the pin supports this

This includes 2 fixes: one introduced in the current release cycle (v6.16-rc1)
and another introduced back in v6.4-rc1. Both have been in linux-next since
next-250701 and have passed the modules ci tests using kdevops. Finally, as Petr
and Luis mentioned in previous pull requests, add myself (Daniel Gomez) to the
list of modules maintainers.
The first was reported by Intel's kernel test robot, and it addresses a crash
exposed by Sebastian's commit c50d295c37 ("rds: Use nested-BH locking for
rds_page_remainder") by allowing relocations for the per-CPU section even if it
lacks the SHF_ALLOC flag. Petr and Sebastian went down to the archive history
(before Git) and found the commit that broke it b3b91325f3c7 ("Don't relocate
non-allocated regions in modules.").
The second fix, reported and fixed by Petr (with additional cleanup), resolves a
memory leak by ensuring proper deallocation if module loading fails. We couldn't
find a reproducer other than forcing it manually or leveraging eBPF. So, I
tested it by enabling error injection in the codetag functions through the error
path that produces the leak and made it fail until execmem is unable to allocate
more memory.

The GICv5 architecture implements Interrupt Translation Service
(ITS) components in order to translate events coming from peripherals
into interrupt events delivered to the connected IRSes.
Events (ie MSI memory writes to ITS translate frame), are translated
by the ITS using tables kept in memory.
ITS translation tables for peripherals is kept in memory storage
(device table [DT] and Interrupt Translation Table [ITT]) that
is allocated by the driver on boot.
Both tables can be 1- or 2-level; the structure is chosen by the
driver after probing the ITS HW parameters and checking the
allowed table splits and supported {device/event}_IDbits.
DT table entries are allocated on demand (ie when a device is
probed); the DT table is sized using the number of supported
deviceID bits in that that's a system design decision (ie the
number of deviceID bits implemented should reflect the number
of devices expected in a system) therefore it makes sense to
allocate a DT table that can cater for the maximum number of
devices.
DT and ITT tables are allocated using the kmalloc interface;
the allocation size may be smaller than a page or larger,
and must provide contiguous memory pages.
LPIs INTIDs backing the device events are allocated one-by-one
and only upon Linux IRQ allocation; this to avoid preallocating
a large number of LPIs to cover the HW device MSI vector
size whereas few MSI entries are actually enabled by a device.
ITS cacheability/shareability attributes are programmed
according to the provided firmware ITS description.
The GICv5 partially reuses the GICv3 ITS MSI parent infrastructure
and adds functions required to retrieve the ITS translate frame
addresses out of msi-map and msi-parent properties to implement
the GICv5 ITS MSI parent callbacks.

The GICv5 CPU interface implements support for PE-Private Peripheral
Interrupts (PPI), that are handled (enabled/prioritized/delivered)
entirely within the CPU interface hardware.
To enable PPI interrupts, implement the baseline GICv5 host kernel
driver infrastructure required to handle interrupts on a GICv5 system.
Add the exception handling code path and definitions for GICv5
instructions.
Add GICv5 PPI handling code as a specific IRQ domain to:
- Set-up PPI priority
- Manage PPI configuration and state
- Manage IRQ flow handler
- IRQs allocation/free
- Hook-up a PPI specific IRQchip to provide the relevant methods
PPI IRQ priority is chosen as the minimum allowed priority by the
system design (after probing the number of priority bits implemented
by the CPU interface).

The GICv5 interrupt controller architecture is composed of:
- one or more Interrupt Routing Service (IRS)
- zero or more Interrupt Translation Service (ITS)
- zero or more Interrupt Wire Bridge (IWB)
Describe a GICv5 implementation by specifying a top level node
corresponding to the GICv5 system component.
IRS nodes are added as GICv5 system component children.
An ITS is associated with an IRS so ITS nodes are described
as IRS children - use the hierarchy explicitly in the device
tree to define the association.
IWB nodes are described as a separate schema.
An IWB is connected to a single ITS, the connection is made explicit
through the msi-parent property and therefore is not required to be
explicit through a parent-child relationship in the device tree.

This driver has long outlived it's utility, and it's broken and unloved.
The main use case for this was direct mount with UDF of cd-rw drives
that required 32kb packets. It would collect writes into that size and
write them out in multiples of that. That's not a common use case
anymore, the world has moved on from those kinds of media. To make
matters worse, it's actively breaking setups where it's not even
required or useful.

io_uring commands provide an ioctl style interface for files to
implement file specific operations. io_uring provides many features and
advanced api to commands, and it's getting hard to test as it requires
specific files/devices.
Add basic infrastucture for creating special mock files that will be
implementing the cmd api and using various io_uring features we want to
test. It'll also be useful to test some more obscure read/write/polling
edge cases in the future.

Currently CONFIG_GENERIC_ENTRY enables both the generic exception
entry logic and the generic syscall entry logic, which are otherwise
loosely coupled.
Introduce separate config options for these so that architectures can
select the two independently. This will make it easier for
architectures to migrate to generic entry code.

[Linus Walleij: rebase onto v6.16-rc1]
Rework how lib/crc/ supports arch-optimized code. First, instead of the
arch-optimized CRC code being in arch/$(SRCARCH)/lib/, it will now be in
lib/crc/$(SRCARCH)/. Second, the API functions (e.g. crc32c()),
arch-optimized functions (e.g. crc32c_arch()), and generic functions
(e.g. crc32c_base()) will now be part of a single module for each CRC
type, allowing better inlining and dead code elimination. The second
change is made possible by the first.
As an example, consider CONFIG_CRC32=m on x86. We'll now have just
crc32.ko instead of both crc32-x86.ko and crc32.ko. The two modules
were already coupled together and always both got loaded together via
direct symbol dependency, so the separation provided no benefit.
Note: later I'd like to apply the same design to lib/crypto/ too, where
often the API functions are out-of-line so this will work even better.
In those cases, for each algorithm we currently have 3 modules all
coupled together, e.g. libsha256.ko, libsha256-generic.ko, and
sha256-x86.ko. We should have just one, inline things properly, and
rely on the compiler's dead code elimination to decide the inclusion of
the generic code instead of manually setting it via kconfig.
Having arch-specific code outside arch/ was somewhat controversial when
Zinc proposed it back in 2018. But I don't think the concerns are
warranted. It's better from a technical perspective, as it enables the
improvements mentioned above. This model is already successfully used
in other places in the kernel such as lib/raid6/. The community of each
architecture still remains free to work on the code, even if it's not in
arch/. At the time there was also a desire to put the library code in
the same files as the old-school crypto API, but that was a mistake; now
that the library is separate, that's no longer a constraint either.

The commit d391c58271 ("drivers/firmware: move x86 Generic System
Framebuffers support") moved the sysfb*.c source files from arch/x86
to drivers/firmware, because the logic wasn't x86 specific and could
be used by other architectures.
But the drivers/firmware path is not listed in MAINTAINERS, which led
to the files being orphaned and scripts/get_maintainer.pl not listing
a mailing list to Cc anymore.
Now that we have an entry for all the firmware-provided framebuffer code,
add the missing sysfb files to make sure correct folks and list is Cc'ed.

In addition to GPIO synchronization, The AD7768-1 also supports
synchronization over SPI, which use is recommended when the GPIO
cannot provide a pulse synchronous with the base MCLK signal. It
consists of looping back the SYNC_OUT to the SYNC_IN pin and send
a command via SPI to trigger the synchronization.
Introduce the 'trigger-sources' property to enable SPI-based
synchronization via SYNC_OUT pin, along with additional optional
entries for GPIO3 and DRDY pins.
Also create #trigger-source-cells property to differentiate the trigger
sources provided by the ADC. To improve readability, create a
adi,ad7768-1.h header with the macros for the cell values.
While at it, add description to the interrupts property.

The OLDI transmitters (TXes) do not have registers of their own, and are
dependent on the source video-ports (VPs) from the DSS to provide
configuration data. This hardware doesn't directly sit on the internal
bus of the SoC, but does so via the DSS. Hence, the OLDI TXes are
supposed to be child nodes under the DSS, and not independent devices.
Two of the OLDI TXes can function in tandem to output dual-link OLDI
output, or cloned single-link outputs. In these cases, one OLDI will be
the primary OLDI, and the other one, a companion. The following diagram
represents such a configuration.
+-----+-----+ +-------+
| | | | |
| | VP1 +----+--->+ OLDI0 | (Primary - may need companion)
| | | | | |
| DSS +-----+ | +-------+
| | | |
| | VP2 | | +-------+
| | | | | |
+-----+-----+ +--->+ OLDI1 | (Companion OLDI)
| |
+-------+
The DSS in AM625 SoC has a configuration like the one above. The AM625
DSS VP1 (port@0) can connect and control 2 OLDI TXes, to use them in
dual-link or cloned single-link OLDI modes. It is only the VP1 that can
connect to either OLDI TXes for the AM625 DSS, and not the VP2.
Alternatively, on some future TI SoCs, along with the above
configuration, the OLDI TX can _also_ connect to separate video sources,
making them work entirely independent of each other. In this case,
neither of the OLDIs are "companion" or "secondary" OLDIs, and nor do
they require one. They both are independent and primary OLDIs. The
following diagram represents such a configuration.
+-----+-----+ +-------+
| | | | |
| | VP1 +--+----------->+ OLDI0 | (Primary - may need companion)
| | | | | |
| +-----+ | +-------+
| | | |
| | VP2 | |
| | | |
| DSS +-----+ | +---+ +-------+
| | | +-->+ M | | |
| | VP3 +----->+ U +--->+ OLDI1 | (Companion or Primary)
| | | | X | | |
| +-----+ +---+ +-------+
| | |
| | VP4 |
| | |
+-----+-----+
Note that depending on the mux configuration, the OLDIs can either be
working together in tandem - sourced by VP1, OR, they could be working
independently sourced by VP1 and VP3 respectively.
The idea is to support all the configurations with this OLDI TX schema.
The OLDI functionality is further supported by a system-control module,
which contains a few registers to control OLDI IO power and other
electrical characteristics of the IO lanes.
Add devicetree binding schema for the OLDI TXes to support various
configurations, and extend their support to the AM625 DSS.

involved in nova-core development, and brings valuable Rust expertise.
In addition to his technical contributions, Alex is actively engaged with
the broader community. He works closely with contributors and
stakeholders to identify and solve issues, fosters collaboration, and
helps ensure that the Nova driver evolves in alignment with the
community.
I trust him to take a key role in making the Nova driver a successful
upstream solution for NVIDIA GPUs in the Linux kernel.

Introduce the pwrseq-thead-gpu driver, a power sequencer provider for
the Imagination BXM-4-64 GPU on the T-HEAD TH1520 SoC. This driver
controls an auxiliary device instantiated by the AON power domain.
The TH1520 GPU requires a specific sequence to correctly initialize and
power down its resources:
- Enable GPU clocks (core and sys).
- De-assert the GPU clock generator reset (clkgen_reset).
- Introduce a short hardware-required delay.
- De-assert the GPU core reset. The power-down sequence performs these
steps in reverse.
Implement this sequence via the pwrseq_power_on and pwrseq_power_off
callbacks.
Crucially, the driver's match function is called when a consumer (the
Imagination GPU driver) requests the "gpu-power" target. During this
match, the sequencer uses clk_bulk_get() and
reset_control_get_exclusive() on the consumer's device to obtain handles
to the GPU's "core" and "sys" clocks, and the GPU core reset. These,
along with clkgen_reset obtained from parent aon node, allow it to
perform the complete sequence.

The ath12k fix to avoid FW crashes requires adding support for a

Brett Creeley is taking ownership of AMD/Pensando drivers while I wander
off into the sunset with my retirement this month. I'll still keep an
eye out on a few topics for awhile, and maybe do some free-lance work in
the future.
Meanwhile, thank you all for the fun and support and the many learning

Special thanks go to DaveM for merging my first patch long ago, the big
ionic patchset a few years ago, and my last patchset last week.

Commit c7f005f70d ("rust: cpu: Add CpuId::current() to retrieve current
CPU ID") adds the file rust/helpers/cpu.c, and intends to add a file entry
for that file in the MAINTAINERS section CPU HOTPLUG. However, the added
file entry is rust/helper/cpu.c; note the subtle difference between the two
file names. Hence, ./scripts/get_maintainer.pl --self-test=patterns
complains about a broken reference.

Accessing device properties is currently done via methods on `Device`
itself, using bindings to device_property_* functions. This is
sufficient for the existing method property_present. However, it's not
sufficient for other device properties we want to access. For example,
iterating over child nodes of a device will yield a fwnode_handle.
That's not a device, so it wouldn't be possible to read the properties
of that child node. Thus, we need an abstraction over fwnode_handle and
methods for reading its properties.
Add a struct FwNode which abstracts over the C struct fwnode_handle.
Implement its reference counting analogous to other Rust abstractions
over reference-counted C structs.
Subsequent patches will add functionality to access FwNode and read
properties with it.

Introduce `CpuId::current()`, a constructor that wraps the C function
`raw_smp_processor_id()` to retrieve the current CPU identifier without
guaranteeing stability.
This function should be used only when the caller can ensure that
the CPU ID won't change unexpectedly due to preemption or migration.

This commit introduces a new vmtest.sh runner for vsock.
It uses virtme-ng/qemu to run tests in a VM. The tests validate G2H,
H2G, and loopback. The testing tools from tools/testing/vsock/ are
reused. Currently, only vsock_test is used.
VMCI and hyperv support is included in the config file to be built with
the -b option, though not used in the tests.
Only tested on x86.
To run:
$ make -C tools/testing/selftests TARGETS=vsock
$ tools/testing/selftests/vsock/vmtest.sh
or
$ make -C tools/testing/selftests TARGETS=vsock run_tests
Example runs (after make -C tools/testing/selftests TARGETS=vsock):
$ ./tools/testing/selftests/vsock/vmtest.sh
1..3
ok 0 vm_server_host_client
ok 1 vm_client_host_server

Future work can include vsock_diag_test.
Because vsock requires a VM to test anything other than loopback, this
patch adds vmtest.sh as a kselftest itself. This is different than other
systems that have a "vmtest.sh", where it is used as a utility script to
spin up a VM to run the selftests as a guest (but isn't hooked into
kselftest).

semi-coherent set of changes, and got all of the different major
subsystems to agree on how this should be implemented both with
changes to their code as well as userspace apis, AND wrangled the
hardware companies into agreeing to go forward with this, despite
making them all redo work they had already done in their private
device trees. This feature offers major power savings on embedded
devices where a USB audio stream can continue to flow while the rest
of the system is sleeping, something that devices running on battery
power really care about. There are still some more small tweaks
left to be done here, and those patches are still out for review and
arguing among the different hardware companies, but this is a major
step forward and a great example of how to do upstream development
well.
- small number of thunderbolt fixes and updates, things seem to be
slowing down here (famous last words...)
- xhci refactors and reworking to try to handle some rough corner
cases in some hardware implementations where things don't always
work properly
- typec driver updates
- USB3 power management reworking and updates
- Removal of some old and orphaned UDC gadget drivers that had not
been used in a very long time, dropping over 11 thousand lines from
the tree, always a nice thing, making up for the 12k lines added for
the USB offload feature.
- lots of little updates and fixes in different drivers
All of these have been in linux-next for over 2 weeks, the USB offload
logic has been in there for 8 weeks now, with no reported issues

Pull USB / Thunderbolt updates from Greg KH:
"Here is the big set of USB and Thunderbolt changes for 6.16-rc1.
Included in here are the following:
- USB offload support for audio devices.
I think this takes the record for the most number of patch series
(30+) over the longest period of time (2+ years) to get merged
properly.
Many props go to Wesley Cheng for seeing this effort through, they
took a major out-of-tree hacked-up-monstrosity that was created by
multiple vendors for their specific devices, got it all merged into
a semi-coherent set of changes, and got all of the different major
subsystems to agree on how this should be implemented both with

Here is the big set of tty and serial driver changes for 6.16-rc1.
A little more churn than normal in this portion of the kernel for this
development cycle, Jiri and Nicholas were busy with cleanups and reviews
and fixes for the vt unicode handling logic which composed most of the
overall work in here.
Major changes are:
- vt unicode changes/reverts/changes from Nicholas. This should help
out a lot with screen readers and others that rely on vt console
support
- lock guard additions to the core tty/serial code to clean up lots of
error handling logic
- 8250 driver updates and fixes
- device tree conversions to yaml
- sh-sci driver updates
- other small cleanups and updates for serial drivers and tty core
portions

Toolchain and infrastructure:
- KUnit '#[test]'s:
- Support KUnit-mapped 'assert!' macros.
The support that landed last cycle was very basic, and the
'assert!' macros panicked since they were the standard library
ones. Now, they are mapped to the KUnit ones in a similar way to
how is done for doctests, reusing the infrastructure there.
With this, a failing test like:
#[test]
fn my_first_test() {
assert_eq!(42, 43);
}
will report:
# my_first_test: ASSERTION FAILED at rust/kernel/lib.rs:251
Expected 42 == 43 to be true, but is false
# my_first_test.speed: normal
not ok 1 my_first_test
- Support tests with checked 'Result' return types.
The return value of test functions that return a 'Result' will be
checked, thus one can now easily catch errors when e.g. using the
'?' operator in tests.
With this, a failing test like:
#[test]
fn my_test() -> Result {
f()?;
Ok(())
}
will report:
# my_test: ASSERTION FAILED at rust/kernel/lib.rs:321
Expected is_test_result_ok(my_test()) to be true, but is false
# my_test.speed: normal
not ok 1 my_test
- Add 'kunit_tests' to the prelude.
- Clarify the remaining language unstable features in use.
- Compile 'core' with edition 2024 for Rust >= 1.87.
- Workaround 'bindgen' issue with forward references to 'enum' types.
- objtool: relax slice condition to cover more 'noreturn' functions.
- Use absolute paths in macros referencing 'core' and 'kernel' crates.
- Skip '-mno-fdpic' flag for bindgen in GCC 32-bit arm builds.
- Clean some 'doc_markdown' lint hits -- we may enable it later on.
'kernel' crate:
- 'alloc' module:
- 'Box': support for type coercion, e.g. 'Box<T>' to 'Box<dyn U>' if
'T' implements 'U'.
- 'Vec': implement new methods (prerequisites for nova-core and
binder): 'truncate', 'resize', 'clear', 'pop',
'push_within_capacity' (with new error type 'PushError'),
'drain_all', 'retain', 'remove' (with new error type
'RemoveError'), insert_within_capacity' (with new error type
'InsertError').
In addition, simplify 'push' using 'spare_capacity_mut', split
'set_len' into 'inc_len' and 'dec_len', add type invariant
'len <= capacity' and simplify 'truncate' using 'dec_len'.
- 'time' module:
- Morph the Rust hrtimer subsystem into the Rust timekeeping
subsystem, covering delay, sleep, timekeeping, timers. This new
subsystem has all the relevant timekeeping C maintainers listed in
the entry.
- Replace 'Ktime' with 'Delta' and 'Instant' types to represent a
duration of time and a point in time.
- Temporarily add 'Ktime' to 'hrtimer' module to allow 'hrtimer' to
delay converting to 'Instant' and 'Delta'.
- 'xarray' module:
- Add a Rust abstraction for the 'xarray' data structure. This
abstraction allows Rust code to leverage the 'xarray' to store
types that implement 'ForeignOwnable'. This support is a dependency
for memory backing feature of the Rust null block driver, which is
waiting to be merged.
- Set up an entry in 'MAINTAINERS' for the XArray Rust support.
Patches will go to the new Rust XArray tree and then via the Rust
subsystem tree for now.
- Allow 'ForeignOwnable' to carry information about the pointed-to
type. This helps asserting alignment requirements for the pointer
passed to the foreign language.
- 'container_of!': retain pointer mut-ness and add a compile-time check
of the type of the first parameter ('$field_ptr').
- Support optional message in 'static_assert!'.
- Add C FFI types (e.g. 'c_int') to the prelude.
- 'str' module: simplify KUnit tests 'format!' macro, convert
'rusttest' tests into KUnit, take advantage of the '-> Result'
support in KUnit '#[test]'s.
- 'list' module: add examples for 'List', fix path of 'assert_pinned!'
(so far unused macro rule).
- 'workqueue' module: remove 'HasWork::OFFSET'.
- 'page' module: add 'inline' attribute.
'macros' crate:
- 'module' macro: place 'cleanup_module()' in '.exit.text' section.
'pin-init' crate:
- Add 'Wrapper<T>' trait for creating pin-initializers for wrapper
structs with a structurally pinned value such as 'UnsafeCell<T>' or
'MaybeUninit<T>'.
- Add 'MaybeZeroable' derive macro to try to derive 'Zeroable', but
not error if not all fields implement it. This is needed to derive
'Zeroable' for all bindgen-generated structs.
- Add 'unsafe fn cast_[pin_]init()' functions to unsafely change the
initialized type of an initializer. These are utilized by the
'Wrapper<T>' implementations.
- Add support for visibility in 'Zeroable' derive macro.
- Add support for 'union's in 'Zeroable' derive macro.
- Upstream dev news: streamline CI, fix some bugs. Add new workflows
to check if the user-space version and the one in the kernel tree
have diverged. Use the issues tab [1] to track them, which should
help folks report and diagnose issues w.r.t. 'pin-init' better.

Documentation:
- Testing: add docs on the new KUnit '#[test]' tests.
- Coding guidelines: explain that '///' vs. '//' applies to private
items too. Add section on C FFI types.
- Quick Start guide: update Ubuntu instructions and split them into
"25.04" and "24.04 LTS and older".
And a few other cleanups and improvements.

Merge tag 'pci-v6.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
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)
