Pull driver core updates from Danilo Krummrich:
"Deferred probe:
- Fix race where deferred probe timeout work could be permanently
canceled by using mod_delayed_work()
- Fix missing jiffies conversion in deferred_probe_extend_timeout()
- Guard timeout extension with delayed_work_pending() to prevent
premature firing
- Use system_percpu_wq instead of the deprecated system_wq
- Update deferred_probe_timeout documentation
device:
- Replace direct struct device bitfield access (can_match, dma_iommu,
dma_skip_sync, dma_ops_bypass, state_synced, dma_coherent,
of_node_reused, offline, offline_disabled) with flag-based
accessors using bit operations
- Reject devices with unregistered buses
- Delete unused DEVICE_ATTR_PREALLOC()
- Add low-level device attribute macros with const show/store
callbacks, allowing device attributes to reside in read-only memory
- Move core device attributes to read-only memory
- Constify group array pointers in driver_add_groups() /
driver_remove_groups(), struct bus_type, and struct device_driver
device property:
- Fix fwnode reference leak in fwnode_graph_get_endpoint_by_id()
- Initialize all fields of fwnode_handle in fwnode_init()
- Provide swnode_get()/swnode_put() wrappers around kobject_get/put()
- Allow passing struct software_node_ref_args pointers directly to
PROPERTY_ENTRY_REF()
driver_override:
- Migrate amba, cdx, vmbus, and rpmsg to the generic driver_override
infrastructure, fixing a UAF from unsynchronized access to
driver_override in bus match() callbacks
- Remove the now-unused driver_set_override()
firmware loader:
- Fix recursive lock deadlock in device_cache_fw_images() when async
work falls back to synchronous execution
- Fix device reference leak in firmware_upload_register()
platform:
- Pass KBUILD_MODNAME through the platform driver registration macro
to create module symlinks in sysfs for built-in drivers; move
module_kset initialization to a pure_initcall and tegra cbb
registration to core_initcall to ensure correct ordering
- Pass THIS_MODULE implicitly through a coresight_init_driver() macro
sysfs:
- Upgrade OOB write detection in sysfs_kf_seq_show() from printk to
WARN
- Add return value clamping to sysfs_kf_read()
Rust:
- ACPI:
Fix missing match data for PRP0001 by exporting
acpi_of_match_device()
- Auxiliary:
Replace drvdata() with dedicated registration data on
auxiliary_device. drvdata() exposed the driver's bus device private
data beyond the driver's own scope, creating ordering constraints
and forcing the data to outlive all registrations that access it.
Registration data is instead scoped structurally to the
Registration object, making lifecycle ordering enforced by
construction rather than convention.
- Rust-native device driver lifetimes (HRT):
Allow Rust device drivers to carry a lifetime parameter on their
bus device private data, tied to the device binding scope -- the
interval during which a bus device is bound to a driver. Device
resources like pci::Bar<'a> and IoMem<'a> can be stored directly in
the driver's bus device private data with a lifetime bounded by the
binding scope, so the compiler enforces at build time that they do
not outlive the binding. This removes Devres indirection from every
access site and eliminates try_access() failure paths in
destructors.
Bus driver traits use a Generic Associated Type (GAT) Data<'bound>
to introduce the lifetime on the private data, rather than
parameterizing the Driver trait itself. Auxiliary registration
data, where the lifetime is not introduced by a trait callback but
must be threaded through Registration, uses the ForLt trait (a
type-level abstraction for types generic over a lifetime).
Misc:
- Fix DT overlayed devices not probing by reverting the broken
treewide overlay fix and re-running fw_devlink consumer pickup when
an overlay is applied to a bound device
- Use root_device_register() for faux bus root device; add sanity
check for failed bus init
- Fix dev_has_sync_state() data race with READ_ONCE() and move it to
base.h
- Avoid spurious device_links warning when removing a device while
its supplier is unbinding
- Switch ISA bus to dynamic root device
- Fix suspicious RCU usage in kernfs_put()
- Remove devcoredump exit callback
- Constify devfreq_event_class"

Make the Data struct lifetime-parameterized, storing a reference to the
parent pci::Device<Bound>. This demonstrates that registration data can
hold device resources tied to the parent driver's lifetime.
In connect(), retrieve the parent PCI device from the registration data

Device::registration_data<F: ForLt>() to return Pin<&F::Of<'_>>.
The stored 'static lifetime is shortened to the borrow lifetime of &self

Convert the sample driver to SampleDriver<'bound>, taking advantage of
the lifetime-parameterized Driver trait.
The driver struct holds &'bound pci::Device directly instead of
ARef<pci::Device>, and pci::Bar<'bound> directly instead of
Devres<pci::Bar>. This removes PinnedDrop, pin_init_scope, and runtime
revocation checks on BAR access.

Convert pci::Bar<SIZE> to pci::Bar<'a, SIZE>, storing &'a Device<Bound>
to tie the BAR mapping lifetime to the device.
iomap_region_sized() now returns Result<Bar<'a, SIZE>> directly instead
of impl PinInit<Devres<Bar<SIZE>>, Error>.
Since the lifetime ties the mapping to the device's bound state, callers
no longer need Devres for the common case where the Bar lives in the
driver's private data.
Add Bar::into_devres() to consume the bar and register it as a
device-managed resource, returning Devres<Bar<'static, SIZE>>. The
lifetime is erased to 'static because Devres guarantees the bar does not
actually outlive the device -- access is revoked on unbind.

Add a type Data<'bound> associated type to all bus driver traits,
decoupling the driver's bus device private data type from the driver
struct itself.
In the context of adding a 'bound lifetime, making this an associated
type has the advantage that it allows us to avoid a driver trait global
lifetime and it avoids the need for ForLt for bus device private data;
both of which make the subsequent implementation by buses much simpler.
All existing drivers and doc examples set type Data = Self to preserve
the current behavior.

Add a registration_data pointer to struct auxiliary_device, allowing the
registering (parent) driver to attach private data to the device at
registration time and retrieve it later when called back by the
auxiliary (child) driver.
By tying the data to the device's registration, Rust drivers can bind
the lifetime of device resources to it, since the auxiliary bus
guarantees that the parent driver remains bound while the auxiliary
device is bound.
On the Rust side, Registration<T> takes ownership of the data via
ForeignOwnable. A TypeId is stored alongside the data for runtime type
checking, making Device::registration_data<T>() a safe method.

Current `dma_read!`, `dma_write!` macros also use a custom
`addr_of!()`-based implementation for projecting pointers, which has
soundness issue as it relies on absence of `Deref` implementation on types.
It also has a soundness issue where it does not protect against unaligned
fields (when `#[repr(packed)]` is used) so it can generate misaligned
accesses.
This commit migrates them to use the general pointer projection
infrastructure, which handles these cases correctly.
As part of migration, the macro is updated to have an improved surface
syntax. The current macro have
dma_read!(a.b.c[d].e.f)
to mean `a.b.c` is a DMA coherent allocation and it should project into it
with `[d].e.f` and do a read, which is confusing as it makes the indexing
operator integral to the macro (so it will break if you have an array of
`CoherentAllocation`, for example).
This also is problematic as we would like to generalize
`CoherentAllocation` from just slices to arbitrary types.
Make the macro expects `dma_read!(path.to.dma, .path.inside.dma)` as the
canonical syntax. The index operator is no longer special and is just one
type of projection (in additional to field projection). Similarly, make
`dma_write!(path.to.dma, .path.inside.dma, value)` become the canonical
syntax for writing.
Another issue of the current macro is that it is always fallible. This
makes sense with existing design of `CoherentAllocation`, but once we
support fixed size arrays with `CoherentAllocation`, it is desirable to
have the ability to perform infallible indexing as well, e.g. doing a `[0]`
index of `[Foo; 2]` is okay and can be checked at build-time, so forcing
falliblity is non-ideal. To capture this, the macro is changed to use
`[idx]` as infallible projection and `[idx]?` as fallible index projection
(those syntax are part of the general projection infra). A benefit of this
is that while individual indexing operation may fail, the overall
read/write operation is not fallible.

MAINTAINERS:
- Add the new driver-core mailing list (driver-core@lists.linux.dev)
to all relevant entries
- Add missing tree location for "FIRMWARE LOADER (request_firmware)"
- Add driver-model documentation to the "DRIVER CORE" entry
- Add missing driver-core maintainers to the "AUXILIARY BUS" entry
Misc:
- Change return type of attribute_container_register() to void; it
has always been infallible
- Do not export sysfs_change_owner(), sysfs_file_change_owner() and
device_change_owner()
- Move devres_for_each_res() from the public devres header to
drivers/base/base.h
- Do not use a static struct device for the faux bus; allocate it
dynamically
Revocable:
- Patches for the revocable synchronization primitive have been
scheduled for v7.0-rc1, but have been reverted as they need some
more refinement
Rust:
- Device:
- Support dev_printk on all device types, not just the core Device
struct; remove now-redundant .as_ref() calls in dev_* print
calls
- Devres:
- Introduce an internal reference count in Devres<T> to avoid a
deadlock condition in case of (indirect) nesting
- DMA:
- Allow drivers to tune the maximum DMA segment size via
dma_set_max_seg_size()
- I/O:
- Introduce the concept of generic I/O backends to handle
different kinds of device shared memory through a common
interface.
This enables higher-level concepts such as register
abstractions, I/O slices, and field projections to be built
generically on top.
In a first step, introduce the Io, IoCapable<T>, and IoKnownSize
trait hierarchy for sharing a common interface supporting offset
validation and bound-checking logic between I/O backends.
- Refactor MMIO to use the common I/O backend infrastructure
- Misc:
- Add __rust_helper annotations to C helpers for inlining into
Rust code
- Use "kernel vertical" style for imports
- Replace kernel::c_str! with C string literals
- Update ARef imports to use sync::aref
- Use pin_init::zeroed() for struct auxiliary_device_id and
debugfs file_operations initialization
- Use LKMM atomic types in debugfs doc-tests
- Various minor comment and documentation fixes
- PCI:
- Implement PCI configuration space accessors using the common I/O
backend infrastructure
- Document pci::Bar device endianness assumptions
- SoC:
- Abstractions for struct soc_device and struct soc_device_attribute
- Sample driver for soc::Device"

The commit 600de1c008b2 ("rust: pci: remove redundant `.as_ref()` for
`dev_*` print") removed `.as_ref()` for `dev_*` prints. Nearly at the
same time the commit e62e48adf76c ("sample: rust: pci: add tests for
config space routines") was merged. Which missed this removal, then.

The previous Io<SIZE> type combined both the generic I/O access helpers
and MMIO implementation details in a single struct. This coupling prevented
reusing the I/O helpers for other backends, such as PCI configuration
space.
Establish a clean separation between the I/O interface and concrete
backends by separating generic I/O helpers from MMIO implementation.
Introduce a new trait hierarchy to handle different access capabilities:
- IoCapable<T>: A marker trait indicating that a backend supports I/O
operations of a certain type (u8, u16, u32, or u64).
- Io trait: Defines fallible (try_read8, try_write8, etc.) and infallibile
(read8, write8, etc.) I/O methods with runtime bounds checking and
compile-time bounds checking.
- IoKnownSize trait: The marker trait for types support infallible I/O
methods.
Move the MMIO-specific logic into a dedicated Mmio<SIZE> type that
implements the Io traits. Rename IoRaw to MmioRaw and update consumers to
use the new types.
