Merge tag 'driver-core-7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core

Pull driver core updates from Danilo Krummrich:
"Bus:

- Ensure bus->match() is consistently called with the device lock
held

- Improve type safety of bus_find_device_by_acpi_dev()

Devtmpfs:

- Parse 'devtmpfs.mount=' boot parameter with kstrtoint() instead of
simple_strtoul()

- Avoid sparse warning by making devtmpfs_context_ops static

IOMMU:

- Do not register the qcom_smmu_tbu_driver in arm_smmu_device_probe()

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"

RISC-V

CPU:
- Expose housekeeping CPUs through /sys/devices/system/cpu/housekeeping
- Print a newline (or 0x0A) instead of '(null)' reading
/sys/devices/system/cpu/nohz_full when nohz_full= is not set

debugfs

- Remove redundant access mode checks in debugfs_get_tree() and
debugfs_create_*() functions

and guarantees the correct private data type)

abstractions to derive the bus device type of the parent device

an IrqVector bound to specific pci::Device into an IrqRequest
bound to the same pci::Device's parent Device
- Leverage pin_init_scope() to get rid of redundant Result in IRQ
methods

- PinInit:
- Add {pin_}init_scope() to execute code before creating an
initializer

- Leverage pin_init_scope() to get rid of redundant Result in IRQ
methods

- Timekeeping:
- Implement abstraction of udelay()

UserSliceWriter
