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"

Merge tag 'rust-6.20-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux

Pull rust updates from Miguel Ojeda:
"Toolchain and infrastructure:

- Add '__rust_helper' annotation to the C helpers

This is needed to inline these helpers into Rust code

- Remove imports available via the prelude, treewide

This was possible thanks to a new lint in Klint that Gary has
implemented -- more Klint-related changes, including initial
upstream support, are coming

- Deduplicate pin-init flags

'kernel' crate:

- Add support for calling a function exactly once with the new
'do_once_lite!' macro (and 'OnceLite' type)

Based on this, add 'pr_*_once!' macros to print only once

- Add 'impl_flags!' macro for defining common bitflags operations:

impl_flags!(
/// Represents multiple permissions.
#[derive(Debug, Clone, Default, Copy, PartialEq, Eq)]
pub struct Permissions(u32);

/// Represents a single permission.
#[derive(Debug, Clone, Copy, PartialEq, Eq)]
pub enum Permission {
/// Read permission.
Read = 1 << 0,

/// Write permission.
Write = 1 << 1,

/// Execute permission.
Execute = 1 << 2,
}
);

let mut f: Permissions = Permission::Read | Permission::Write;
assert!(f.contains(Permission::Read));
assert!(!f.contains(Permission::Execute));

f |= Permission::Execute;
assert!(f.contains(Permission::Execute));

let f2: Permissions = Permission::Write | Permission::Execute;
assert!((f ^ f2).contains(Permission::Read));
assert!(!(f ^ f2).contains(Permission::Write));

- 'bug' module: support 'CONFIG_DEBUG_BUGVERBOSE_DETAILED' in the
'warn_on!' macro in order to show the evaluated condition alongside
the file path:

------------[ cut here ]------------
WARNING: [val == 1] linux/samples/rust/rust_minimal.rs:27 at ...
Modules linked in: rust_minimal(+)

- Add safety module with 'unsafe_precondition_assert!' macro,
currently a wrapper for 'debug_assert!', intended to mark the
validation of safety preconditions where possible:

/// # Safety
///
/// The caller must ensure that `index` is less than `N`.
unsafe fn set_unchecked(&mut self, index: usize, value: T) {
unsafe_precondition_assert!(
index < N,
"set_unchecked() requires index ({index}) < N ({N})"
);

...
}

- Add instructions to 'build_assert!' documentation requesting to
always inline functions when used with function arguments

- 'ptr' module: replace 'build_assert!' with a 'const' one

- 'rbtree' module: reduce unsafe blocks on pointer derefs

- 'transmute' module: implement 'FromBytes' and 'AsBytes' for
inhabited ZSTs, and use it in Nova

- More treewide replacements of 'c_str!' with C string literals

'macros' crate:

- Rewrite most procedural macros ('module!', 'concat_idents!',
'#[export]', '#[vtable]', '#[kunit_tests]') to use the 'syn'
parsing library which we introduced last cycle, with better
diagnostics

This also allows to support '#[cfg]' properly in the '#[vtable]'
macro, to support arbitrary types in 'module!' macro (not just an
identifier) and to remove several custom parsing helpers we had

- Use 'quote!' from the recently vendored 'quote' library and remove
our custom one

The vendored one also allows us to avoid quoting '"' and '{}'
inside the template anymore and editors can now highlight it. In
addition, it improves robustness as it eliminates the need for
string quoting and escaping

- Use 'pin_init::zeroed()' to simplify KUnit code

'pin-init' crate:

- Rewrite all procedural macros ('[pin_]init!', '#[pin_data]',
'#[pinned_drop]', 'derive([Maybe]Zeroable)') to use the 'syn'
parsing library which we introduced last cycle, with better
diagnostics

- Implement 'InPlaceWrite' for '&'static mut MaybeUninit<T>'. This
enables users to use external allocation mechanisms such as
'static_cell'

- Support tuple structs in 'derive([Maybe]Zeroable)'

- Support attributes on fields in '[pin_]init!' (such as
'#[cfg(...)]')

- Add a '#[default_error(<type>)]' attribute to '[pin_]init!' to
override the default error (when no '? Error' is specified)

- Support packed structs in '[pin_]init!' with
'#[disable_initialized_field_access]'

- Remove 'try_[pin_]init!' in favor of merging their feature with
'[pin_]init!'. Update the kernel's own 'try_[pin_]init!' macros to
use the 'default_error' attribute

- Correct 'T: Sized' bounds to 'T: ?Sized' in the generated
'PinnedDrop' check by '#[pin_data]'

Documentation:

- Conclude the Rust experiment

MAINTAINERS:

- Add "RUST [RUST-ANALYZER]" entry for the rust-analyzer support.
Tamir and Jesung will take care of it. They have both been active
around it for a while. The new tree will flow through the Rust one

- Add Gary as maintainer for "RUST [PIN-INIT]"

- Update Boqun and Tamir emails to their kernel.org accounts

And a few other cleanups and improvements"

rust: auxiliary: unregister on parent device unbind

Guarantee that an auxiliary driver will be unbound before its parent is
unbound; there is no point in operating an auxiliary device whose parent
has been unbound.

In practice, this guarantee allows us to assume that for a bound
auxiliary device, also the parent device is bound.

This is useful when an auxiliary driver calls into its parent, since it
allows the parent to directly access device resources and its device
private data due to the guaranteed bound device context.

rust: driver: let probe() return impl PinInit<Self, Error>

The driver model defines the lifetime of the private data stored in (and
owned by) a bus device to be valid from when the driver is bound to a
device (i.e. from successful probe()) until the driver is unbound from
the device.

This is already taken care of by the Rust implementation of the driver
model. However, we still ask drivers to return a Result<Pin<KBox<Self>>>
from probe().

Unlike in C, where we do not have the concept of initializers, but
rather deal with uninitialized memory, drivers can just return an
impl PinInit<Self, Error> instead.

This contributes to more clarity to the fact that a driver returns it's
device private data in probe() and the Rust driver model owns the data,
manages the lifetime and - considering the lifetime - provides (safe)
accessors for the driver.

Hence, let probe() functions return an impl PinInit<Self, Error> instead
of Result<Pin<KBox<Self>>>.
