dt-bindings: usb: add Rohm BM92TXX Type-C controller
Add the device-tree binding documentation for the Rohm BM92TXX family
of USB Type-C and Power Delivery controllers. The device is controlled
over I2C and signals state changes through a dedicated interrupt line.
Document the rohm,* properties consumed by the driver: the optional
VCONN-enable GPIO, the DisplayPort alternate-mode toggles
(rohm,dp-disable, rohm,dp-alerts-enable, rohm,dp-signal-toggle-on-resume,
rohm,dp-lanes), the suspend/dock tunables (rohm,led-static-on-suspend,
rohm,dock-power-limit-disable) and the four
rohm,pd-{5,9,12,15}v-current-limit-ma per-PDO charging current limits.
A graph port is required to link the controller to a USB role switch
consumer.

usb: typec: bm92txx: add Rohm BM92TXX support
Add a driver for the Rohm Semiconductor BM92TXX family of USB Type-C and Power Delivery controllers. The IC integrates an MCU that runs the PD state machine; the host configures it and observes status over I2C and reacts to a level-triggered ALERT interrupt. The driver exposes the controller through extcon and a USB role switch, manages the VBUS sink, optional VBUS source and battery-charger regulators along with the VCONN-enable GPIO, and applies per-PDO charging current limits (5 V, 9 V, 12 V, 15 V) sourced from device tree. DisplayPort alternate-mode handling and dock LED behaviour are configurable through rohm,* properties so the same driver can serve boards that wire the part up differently. A debugfs interface under bm92txx/ is provided for register dumps and low-level command access when CONFIG_DEBUG_FS is enabled.

Merge tag 'net-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Work on removing rtnl_lock protection throughout the stack
continues. In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal
- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.
- Support dumping qdiscs and page pools for a specific netdev. Even
tho user space wants a dump of all netdevs, most of the time, the
OOO programming model results in repeating the dump for each
netdev. Which, in absence of a cache, leads to a O(n^2) behavior.
- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on
retransmit timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 >
40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).
- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).
- Support binding GENEVE tunnels to a local address.
- Speed up UDP tunnel destruction (remove one synchronize_rcu()).
- Support exponential field encoding in multicast (IGMPv3 and MLDv2).
- Support attaching PSP crypto offload to containers (veth, netkit).
- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.
The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot
express reqid changes or migrate Transport mode selectors.
The new interface identifies the SA via SPI and mark, supports
reqid changes, address family changes, encap removal, and uses an
atomic create+install flow under x->lock to prevent SN/IV reuse
during AEAD SA migration.
- Implement GRO/GSO support for PPPoE.
- Convert sockopt callbacks in a number of protocols to iov_iter.
Cross-tree stuff:
- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto
API users, since it changed crypto transformation objects into
reference-counted objects.
- Add FCrypt-PCBC implementation to rxrpc and remove it from the
global crypto API as obsolete and insecure.
Wireless:
- Major rework of station bandwidth handling, fixing issues with
lower capability than AP.
- Cleanups for EMLSR spec issues (drafts differed).
- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)
- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).
- Fine Timing Measurement ranging (i.e. distance measurement) APIs.
Netfilter:
- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.
- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.
Deletions:
- Remove TLS + sockmap integration. TLS wants to pin user pages to
avoid a copy, and sockmap wants to write to the input stream. More
work on this integration is clearly needed, and we can't find any
users (original author admitted that they never deployed it).
- Remove support for TLS offload with TCP Offload Engine (the far
more common opportunistic offload is retained). The locking looks
unfixable (driver sleeps under TCP spin locks) and people from the
vendor that added this are AWOL.
- Remove more ATM code, trying to leave behind only what PPPoATM
needs, AAL5 and br2684 with permanent circuits.
- Remove AppleTalk. Let it join hamradio in our out of tree protocol
graveyard, I mean, repository.
- Disable 32-bit x_tables compatibility (32bit binaries on 64bit
kernel) interface in user namespaces. To be deleted completely,
soon.
- Remove 5/10 MHz support from cfg80211/mac80211.
Drivers:
- Software:
- Support DEVMEM/DMABUF Tx over NETMEM_TX_NO_DMA devices (netkit)
- bonding: add knob to strictly follow 802.3ad for link state

- Alibaba Elastic Ethernet Adaptor (cloud vNIC).
- NXP NETC switch within i.MX94.
- DPLL:

tunnels
- nVidia/Mellanox:

- expose more per-queue stats over the standard API
- support additional, unprivileged PFs in the DPU
configuration
- support Socket Direct (multi-PF) with switchdev offloads
- add a pool / frag allocator for DMA mapped buffers for
control objects, save memory on systems with 64kB page size
- take advantage of the ability to dynamically change RSS
table size, even when table is configured by the user
- increase the max RSS table size for even traffic
distribution

appletalk: move the protocol out of tree
AppleTalk has been removed in MacOS X 10.6 (Snow Leopard), in 2009, according to Wikipedia. We recently got a burst of AI generated fixes to this protocol which nobody is reviewing. Let AppleTalk follow AX.25 and hamradio out of the Linux tree. We we will maintain the code at: github.com/linux-netdev/mod-orphan for anyone interested in playing with it. Retain the uAPI for now. No strong reason, simply because I suspect keeping it will be less controversial.

Merge tag 'for-7.2/io_uring-20260615' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux
Pull io_uring updates from Jens Axboe: - Rework the task_work infrastructure. Both the local (DEFER_TASKRUN) and the normal (tctx) task_work lists were llist based, which is LIFO ordered, and hence each run had to do an O(n) list reversal pass first to restore queue order. Additionally, to cap the amount of task_work run, each method needed a retry list as well. Add a lockless MPCS FIFO queue (based on Dmitry Vyukov's intrusive MPSC algorithm) and switch both task_work lists to it. It performs better than llists and we can then also ditch the retry lists as well as entries are popped one-at-the-time. On top of those changes, run the tctx fallback task_work directly and remove the now-unused per-ctx fallback machinery entirely. - zcrx user notifications. Add a mechanism for zcrx to communicate conditions back to userspace via a dedicated CQE, with the initial users being notification on running out of buffers and on a frag copy fallback, plus shared-memory notification statistics. Alongside that, a series of zcrx reliability and cleanup fixes: more reliable scrubbing, poisoning pointers on unregistration, dropping an extra ifq close, adding a ctx back-pointer, reordering fd allocation in the export path, and killing a dead 'sock' member. - Allow using io_uring registered buffers for plain SEND and RECV, not just for the zero-copy send path. This enables targets like ublk's NBD backend to push/pull IO data directly to/from a registered buffer over a plain send/recv on a TCP socket. - Registered buffer improvements: account huge pages correctly, bump the io_mapped_ubuf length field to size_t, and raise the previous 1GB registered buffer size limit. - Restrict the ctx access exposed to io_uring BPF struct_ops programs by handing them an opaque type rather than the full io_ring_ctx, and add a separate MAINTAINERS entry for the bpf-ops code. - Allow opcode filtering on IORING_OP_CONNECT. - Validate ring-provided buffer addresses with access_ok(), and align the legacy buffer add limit with MAX_BIDS_PER_BGID. - Various other cleanups and minor fixes, including avoiding msghdr async data on connect/bind, dropping async_size for OP_LISTEN, making the POLL_FIRST receive side checks consistent, re-checking IO_WQ_BIT_EXIT for each linked work item, and using trace_call__##name() at guarded tracepoint call sites. * tag 'for-7.2/io_uring-20260615' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (31 commits) io_uring/bpf-ops: add a separate maintainer entry io_uring/net: make POLL_FIRST receive side checks consistent io_uring: remove the per-ctx fallback task_work machinery io_uring: run the tctx task_work fallback directly io_uring: switch normal task_work to a mpscq io_uring: switch local task_work to a mpscq io_uring/mpscq: add lockless multi-producer, single-consumer FIFO queue io_uring: grab RCU read lock marking task run io_uring/zcrx: kill dead 'sock' member in struct io_zcrx_args io_uring/kbuf: validate ring provided buffer addresses with access_ok() io_uring/net: support registered buffer for plain send and recv io_uring/nop: Drop a wrong comment in struct io_nop io_uring/net: Remove async_size for OP_LISTEN io_uring/net: Avoid msghdr on op_connect/op_bind async data io_uring/bpf-ops: restrict ctx access to BPF io_uring/io-wq: re-check IO_WQ_BIT_EXIT for each linked work item io_uring/kbuf: align legacy buffer add limit with MAX_BIDS_PER_BGID io_uring/zcrx: add shared-memory notification statistics io_uring/zcrx: notify user on frag copy fallback io_uring/zcrx: notify user when out of buffers ... |

Pull arm64 updates from Will Deacon:
"It feels like the new world of AI tooling has slowed us down a little
on the feature side when compared to the fixes side. The extra rounds
of Sashiko review have also pushed a few things out until next time.
Still, there's some good foundational stuff here for the fpsimd code
and hardening work towards removing the predictable linear alias of
the kernel image.
CPU errata handling:
- Extend CnP disabling workaround to HiSilicon HIP09 hardware.
- Work around eternally broken broadcast TLB invalidation on more
CPUs.
- Documentation and code cleanups.
CPU features:
- Add new hwcaps for the 2025 dpISA extensions.
Floating point / SVE / SME:
- Significant cleanup to the low-level state management code in the
core architecture code and KVM.
- Use correct register widths during SVE/SME save/restore assembly.
- Expose SVE/SME save/restore memory accesses to sanitisers.
Memory management:
- Preparatory work for unmapping the kernel data and bss sections
from the linear map.
Miscellaneous:
- Inline DAIF manipulation helpers so they can be used safely from
non-instrumentable code.
- Fix handling of the 'nosmp' cmdline option to avoid marking
secondary cores as "possible".
MPAM:
- Add support for v0.1 of the MPAM architecture.
Perf:
- Update HiSilicon PMU MAINTAINERS entry.
- Fix event encodings for the DVM node in the CMN driver.
Selftests:
- Extend sigframe tests to cover POE context.
- Add coverage for the newly added 2025 dpISA hwcaps.
System registers:
- Add new registers and ESR encodings for the HDBSS feature.
Plus minor fixes and cleanups across the board"

Pull locking updates from Ingo Molnar:
"Futex updates:
- Optimize futex hash bucket access patterns (Peter Zijlstra)
- Large series to address the robust futex unlock race for real, by
Thomas Gleixner:
"The robust futex unlock mechanism is racy in respect to the
clearing of the robust_list_head::list_op_pending pointer because
unlock and clearing the pointer are not atomic.
The race window is between the unlock and clearing the pending op
pointer. If the task is forced to exit in this window, exit will
access a potentially invalid pending op pointer when cleaning up
the robust list.
That happens if another task manages to unmap the object
containing the lock before the cleanup, which results in an UAF.
In the worst case this UAF can lead to memory corruption when
unrelated content has been mapped to the same address by the time
the access happens.
User space can't solve this problem without help from the kernel.
This series provides the kernel side infrastructure to help it
along:
1) Combined unlock, pointer clearing, wake-up for the
contended case
2) VDSO based unlock and pointer clearing helpers with a
fix-up function in the kernel when user space was interrupted
within the critical section.

Rust:

- 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

Merge tag 'rust-7.2' of gitolite.kernel.org:pub/scm/linux/kernel/git/ojeda/linux
Pull Rust updates from Miguel Ojeda:
"This one is big due to the vendoring of the `zerocopy` library, which
allows us to replace a bunch of `unsafe` code dealing with conversions
between byte sequences and other types with safe alternatives. More
details on that below (and in its merge commit).
Toolchain and infrastructure:
- Introduce support for the 'zerocopy' library [1][2]:
Fast, safe, compile error. Pick two.
Zerocopy makes zero-cost memory manipulation effortless. We write
`unsafe` so you don't have to.
It essentially provides derivable traits (e.g. 'FromBytes') and
macros (e.g. 'transmute!') for safely converting between byte
sequences and other types. Having such support allows us to remove
some 'unsafe' code.
It is among the most downloaded Rust crates and it is also used by
the Rust compiler itself.
It is licensed under "BSD-2-Clause OR Apache-2.0 OR MIT".
The crates are imported essentially as-is (only +2/-3 lines needed
to be adapted), plus SPDX identifiers. Upstream has since added the
SPDX identifiers as well as one of the tweaks at my request, thus
reducing our future diffs on updates -- I keep the details in one
of our usual live lists [3].
In total, it is about ~39k lines added, ~32k without counting
'benches/' which are just for documentation purposes.
The series includes a few Kbuild and rust-analyzer improvements and
an example patch using it in Nova, removing one 'unsafe impl'.
I checked that the codegen of an isolated example function (similar
to the Nova patch on top) is essentially identical. It also turns
out that (for that particular case) the 'zerocopy' version, even
with 'debug-assertions' enabled, has no remaining panics, unlike a
few in the current code (since the compiler can prove the remaining
'ub_checks' statically).
So their "fast, safe" does indeed check out -- at least in that
case.
- Support AutoFDO. This allows Rust code to be profiled and optimized
based on the profile. Tested with Rust Binder: ~13% slower without
AutoFDO in the binderAddInts benchmark (using an app-launch
benchmark for the profile).
- Support Software Tag-Based KASAN.
In addition, fix KASAN Kconfig by requiring Clang.
- Add Kconfig options for each existing Rust KUnit test suite, such
as 'CONFIG_RUST_BITMAP_KUNIT_TEST'.
They are placed within a new menu, 'CONFIG_RUST_KUNIT_TESTS', in
the new 'rust/kernel/Kconfig.test' file.
- Support the upcoming Rust 1.98.0 release (expected 2026-08-20):
lint cleanups and an unstable flag rename.
- Disable 'rustdoc' documentation inlining for all prelude items,
which bloats the generated documentation.
- Ignore (in Git) and clean (in Kbuild) the (rarely) 'rustc'-generated
'*.long-type-*.txt' files.
'kernel' crate:
- Add new 'bitfield' module with the 'bitfield!' macro (extracted
from the existing 'register!' one), which declares integer types
that are split into distinct bit fields of arbitrary length.
Each field is a 'Bounded' of the appropriate bit width (ensuring
values are properly validated and avoiding implicit data loss) and
gets several generated getters and setters (infallible, 'const' and
fallible) as well as associated constants ('_MASK', '_SHIFT' and
'_RANGE'). It also supports fields that can be converted from/to
custom types, either fallibly ('?=>') or infallibly ('=>').
For instance:
bitfield! {
struct Rgb(u16) {
15:11 blue;
10:5 green;
4:0 red;
}
}
// Compile-time checks.
let color = Rgb::zeroed().with_const_green::<0x1f>();
assert_eq!(color.green(), 0x1f);
assert_eq!(color.into_raw(), 0x1f << Rgb::GREEN_SHIFT);
Add as well documentation and a test suite for it, as usual; and
update the 'register!' macro to use it.
It will be maintained by Alexandre Courbot (with Yury Norov as
reviewer) under a new 'MAINTAINERS' entry: 'RUST [BITFIELD]'.
- 'ptr' module: rework index projection syntax into keyworded syntax
and introduce panicking variant.
The keyword syntax ('build:', 'try:', 'panic:') is more explicit
and paves the way of perhaps adding more flavors in the future,
e.g. an 'unsafe' index projection.
For instance, projections now look like this:
fn f(p: *const [u8; 32]) -> Result {
// Ok, within bounds, checked at build time.
project!(p, [build: 1]);
// Build error.
project!(p, [build: 128]);
// `OutOfBound` runtime error (convertible to `ERANGE`).
project!(p, [try: 128]);
// Runtime panic.
project!(p, [panic: 128]);
Ok(())
}
Update as well the users, which now look like e.g.
// Pointer to the first entry of the GSP message queue.
let data = project!(self.0.as_ptr(), .gspq.msgq.data[build: 0]);
- 'build_assert' module: make the module the home of its macros
instead of rendering them twice.
- 'sync' module: add 'UniqueArc::as_ptr()' associated function.
- 'alloc' module:
- Fix the 'Vec::reserve()' doctest to properly account for the
existing vector length in the capacity assertion.
- Fix an incorrect operator in the 'Vec::extend_with()' 'SAFETY'
comment; add a doc test demonstrating basic usage and the
zero-length case.
- Clean imports across several modules to follow the "kernel
vertical" import style in order to minimize conflicts.
'pin-init' crate:
- User visible changes:
- Do not generate 'non_snake_case' warnings for identifiers that
are syntactically just users of a field name. This would allow
all '#[allow(non_snake_case)]' in nova-core to be removed,
which Gary will send to the nova tree next cycle.
- Filter non-cfg attributes out properly in derived structs. This
improves pin-init compatibility with other derive macros.
- Insert projection types' where clause properly.
- Other changes:
- Bump MSRV to 1.82, plus associated cleanups.
- Overhaul how init slots are projected. The new approach is
easier to justify with safety comments.
- Mark more functions as inline, which should help mitigate the
super-long symbol name issue due to lack of inlining.
rust-analyzer:
- Support '--envs' for passing env vars for crates like 'zerocopy'.
'MAINTAINERS':
- Add the following reviewers to the 'RUST' entry:
- Daniel Almeida
- Tamir Duberstein
- Alexandre Courbot
- Onur Özkan
They have been involved in the Rust for Linux project for about 7
collective years and bring expertise across several domains, which
will be very useful to have around in the future.
Thanks everyone for stepping up!
And some other fixes, cleanups and improvements"

Pull exportfs updates from Christian Brauner: "This cleans up the exportfs support for block-style layouts that provide direct block device access: the operations for layout-based block device access are split out of struct export_operations into a separate header, ->commit_blocks() no longer takes a struct iattr argument, and the way support for layout-based block device access is detected is reworked. nfsd's blocklayout code also stops honoring loca_time_modify. This is preparation for supporting export of more than a single device per file system" * tag 'vfs-7.2-rc1.exportfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: exportfs,nfsd: rework checking for layout-based block device access support exportfs: don't pass struct iattr to ->commit_blocks exportfs: split out the ops for layout-based block device access nfsd/blocklayout: always ignore loca_time_modify |

Merge tag 'i2c-for-7.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c fixes from Wolfram Sang:
"The biggest news here is that this is my last pull request as I2C
maintainer after 13.5 years. Starting with the 7.2 cycle, Andi Shyti
is taking over who helped me greatly maintaining the host drivers for
a while now. Thank you, Andi, and good luck with the subsystem. I'll
be around for help, of course.
Technically, there are two patches which might be a tad large for this
late cycle, but most of them is explaining comments, so I think they
are suitable.
- MAINTAINERS:
- hand over I2C maintainership to Andi
- minor updates
- rust: fix I2cAdapter refcount double increment
- imx: keep clock and pinctrl states consistent in runtime PM
- imx-lpi2c: fix DMA resource leaks on PIO fallback
- qcom-cci: fix NULL pointer dereference on remove
- riic: fix reset refcount leak on resume_noirq error path
- stm32f7: account for analog filter in timing computation
- tegra:
- fix suspend/resume handling in NOIRQ phase
- update Tegra410 I2C timings to match hardware specs"

MAINTAINERS: hand over I2C to Andi Shyti
After 13.5 years of maintaining I2C, it is finally time for me to move to other areas. So, I hereby transfer I2C maintainership to Andi Shyti. He has been taking care of the I2C host drivers for a while now and kindly agreed to look after the whole subsystem. Thank you, Andi! I also want to thank all contributors, reviewers, and fellow maintainers making all these years a mostly smooth ride. Happy hacking, everyone!
