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"
