Pull bcachefs updates from Kent Overstreet:
- More safety fixes, primarily found by syzbot
- Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is
primarily for testing fsck/recovery in dry run mode, so it shouldn't
change anything besides disabling writes and holding dirty metadata
in memory.
The idea here was to reduce the amount of activity if we can't write
anything out, so that bringing up a filesystem in "super ro" mode
would be more lilkely to work for data recovery - but norecovery is
the correct option for this.
- btree_trans->locked; we now track whether a btree_trans has any btree
nodes locked, and this is used for improved assertions related to
trans_unlock() and trans_relock(). We'll also be using it for
improving how we work with lockdep in the future: we don't want
lockdep to be tracking individual btree node locks because we take
too many for lockdep to track, and it's not necessary since we have a
cycle detector.
- Trigger improvements that are prep work for online fsck
- BTREE_TRIGGER_check_repair; this regularizes how we do some repair
work for extents that goes with running triggers in fsck, and fixes
some subtle issues with transaction restarts there.
- bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot
equivalence classes are for when snapshot deletion leaves behind
redundant snapshot nodes, but snapshot deletion now cleans this up
right away, so the abstraction doesn't need to leak.
- Improvements to how we resume writing to the journal in recovery. The
code for picking the new place to write when reading the journal is
greatly simplified and we also store the position in the superblock
for when we don't read the journal; this means that we preserve more
of the journal for list_journal debugging.
- Improvements to sysfs btree_cache and btree_node_cache, for debugging
memory reclaim.
- We now detect when we've blocked for 10 seconds on the allocator in
the write path and dump some useful info.
- Safety fixes for devices references: this is a big series that
changes almost all device lookups to properly check if the device
exists and take a reference to it.
Previously we assumed that if a bkey exists that references a device
then the device must exist, and this was enforced in .invalid
methods, but this was incorrect because it meant device removal
relied on accounting being correct to not leave keys pointing to
invalid devices, and that's not something we can assume.
Getting the "pointer to invalid device" checks out of our .invalid()
methods fixes some long standing device removal bugs; the only
outstanding bug with device removal now is a race between the discard
path and deleting alloc info, which should be easily fixed.
- The allocator now prefers not to expand the new
member_info.btree_allocated bitmap, meaning if repair ever requires
scanning for btree nodes (because of a corrupt interior nodes) we
won't have to scan the whole device(s).
- New coding style document, which among other things talks about the
correct usage of assertions

Pull nfsd updates from Chuck Lever:
"This is a light release containing mostly optimizations, code clean-
ups, and minor bug fixes. This development cycle has focused on non-
upstream kernel work:
1. Continuing to build upstream CI for NFSD, based on kdevops
2. Backporting NFSD filecache-related fixes to selected LTS kernels
One notable new feature in v6.10 NFSD is the addition of a new netlink
protocol dedicated to configuring NFSD. A new user space tool,
nfsdctl, is to be added to nfs-utils. Lots more to come here.

"Aside from the usual things this has an arch update for

Pull clk updates from Stephen Boyd:
"I'm actually surprised this time. There aren't any new Qualcomm SoC
clk drivers. And there's zero diff in the core clk framework.
Instead we have new clk drivers for STM and Sophgo, with
Samsung^WGoogle in third for the diffstat because they introduced HSI0

things like PCIe, UFS, and MMC).
Beyond those big diffs there's the usual updates to various clk
drivers for incorrect parent descriptions or mising
MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
interesting here.

Pull more io_uring updates from Jens Axboe:
"This adds support for IORING_CQE_F_SOCK_NONEMPTY for io_uring accept
requests.
This is very similar to previous work that enabled the same hint for
doing receives on sockets. By far the majority of the work here is
refactoring to enable the networking side to pass back whether or not
the socket had more pending requests after accepting the current one,
the last patch just wires it up for io_uring.
Not only does this enable applications to know whether there are more
connections to accept right now, it also enables smarter logic for
io_uring multishot accept on whether to retry immediately or wait for
a poll trigger"

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing ring buffer updates from Steven Rostedt:
"Add ring_buffer memory mappings.
The tracing ring buffer was created based on being mostly used with
the splice system call. It is broken up into page ordered sub-buffers
and the reader swaps a new sub-buffer with an existing sub-buffer
that's part of the write buffer. It then has total access to the
swapped out sub-buffer and can do copyless movements of the memory
into other mediums (file system, network, etc).
The buffer is great for passing around the ring buffer contents in the
kernel, but is not so good for when the consumer is the user space
task itself.
A new interface is added that allows user space to memory map the ring
buffer. It will get all the write sub-buffers as well as reader
sub-buffer (that is not written to). It can send an ioctl to change
which sub-buffer is the new reader sub-buffer.
The ring buffer is read only to user space. It only needs to call the
ioctl when it is finished with a sub-buffer and needs a new sub-buffer
that the writer will not write over.
A self test program was also created for testing and can be used as an
example for the interface to user space. The libtracefs (external to
the kernel) also has code that interacts with this, although it is
disabled until the interface is in a official release. It can be
enabled by compiling the library with a special flag. This was used
for testing applications that perform better with the buffer being
mapped.
Memory mapped buffers have limitations. The main one is that it can
not be used with the snapshot logic. If the buffer is mapped,
snapshots will be disabled. If any logic is set to trigger snapshots
on a buffer, that buffer will not be allowed to be mapped"

git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl
Pull sysctl updates from Joel Granados:
- Remove sentinel elements from ctl_table structs in kernel/*
Removing sentinels in ctl_table arrays reduces the build time size
and runtime memory consumed by ~64 bytes per array. Removals for
net/, io_uring/, mm/, ipc/ and security/ are set to go into mainline
through their respective subsystems making the next release the most
likely place where the final series that removes the check for
proc_name == NULL will land.
This adds to removals already in arch/, drivers/ and fs/.
- Adjust ctl_table definitions and references to allow constification
- Remove unused ctl_table function arguments
- Move non-const elements from ctl_table to ctl_table_header
- Make ctl_table pointers const in ctl_table_root structure
Making the static ctl_table structs const will increase safety by
keeping the pointers to proc_handler functions in .rodata. Though no
ctl_tables where made const in this PR, the ground work for making
that possible has started with these changes sent by Thomas
Weißschuh.

mess which was worked around by making hotplug processing
asynchronous. The asynchronity isn't great and led to other issues.
We tried to make the behavior synchronous a while ago but that led to
lockdep splats. Waiman took another stab at cleaning up and making it
synchronous. The patch has been in -next for well over a month and
there haven't been any complaints, so fingers crossed.

If an error happens in ftrace, ftrace_kill() will prevent disarming
kprobes. Eventually, the ftrace_ops associated with the kprobes will be
freed, yet the kprobes will still be active, and when triggered, they
will use the freed memory, likely resulting in a page fault and panic.
This behavior can be reproduced quite easily, by creating a kprobe and
then triggering a ftrace_kill(). For simplicity, we can simulate an
ftrace error with a kernel module like [1]:
[1]: https://github.com/brenns10/kernel_stuff/tree/master/ftrace_killer
sudo perf probe --add commit_creds
sudo perf trace -e probe:commit_creds
# In another terminal
make
sudo insmod ftrace_killer.ko # calls ftrace_kill(), simulating bug
# Back to perf terminal
# ctrl-c
sudo perf probe --del commit_creds
After a short period, a page fault and panic would occur as the kprobe
continues to execute and uses the freed ftrace_ops. While ftrace_kill()
is supposed to be used only in extreme circumstances, it is invoked in
FTRACE_WARN_ON() and so there are many places where an unexpected bug
could be triggered, yet the system may continue operating, possibly
without the administrator noticing. If ftrace_kill() does not panic the
system, then we should do everything we can to continue operating,
rather than leave a ticking time bomb.

Pull KVM updates from Paolo Bonzini:
"ARM:
- Move a lot of state that was previously stored on a per vcpu basis
into a per-CPU area, because it is only pertinent to the host while
the vcpu is loaded. This results in better state tracking, and a
smaller vcpu structure.
- Add full handling of the ERET/ERETAA/ERETAB instructions in nested
virtualisation. The last two instructions also require emulating
part of the pointer authentication extension. As a result, the trap
handling of pointer authentication has been greatly simplified.
- Turn the global (and not very scalable) LPI translation cache into
a per-ITS, scalable cache, making non directly injected LPIs much
cheaper to make visible to the vcpu.
- A batch of pKVM patches, mostly fixes and cleanups, as the
upstreaming process seems to be resuming. Fingers crossed!
- Allocate PPIs and SGIs outside of the vcpu structure, allowing for
smaller EL2 mapping and some flexibility in implementing more or
less than 32 private IRQs.
- Purge stale mpidr_data if a vcpu is created after the MPIDR map has
been created.
- Preserve vcpu-specific ID registers across a vcpu reset.
- Various minor cleanups and improvements.
LoongArch:
- Add ParaVirt IPI support
- Add software breakpoint support
- Add mmio trace events support
RISC-V:
- Support guest breakpoints using ebreak
- Introduce per-VCPU mp_state_lock and reset_cntx_lock
- Virtualize SBI PMU snapshot and counter overflow interrupts
- New selftests for SBI PMU and Guest ebreak
- Some preparatory work for both TDX and SNP page fault handling.
This also cleans up the page fault path, so that the priorities of
various kinds of fauls (private page, no memory, write to read-only
slot, etc.) are easier to follow.
x86:
- Minimize amount of time that shadow PTEs remain in the special
REMOVED_SPTE state.
This is a state where the mmu_lock is held for reading but
concurrent accesses to the PTE have to spin; shortening its use
allows other vCPUs to repopulate the zapped region while the zapper
finishes tearing down the old, defunct page tables.
- Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID
field, which is defined by hardware but left for software use.
This lets KVM communicate its inability to map GPAs that set bits
51:48 on hosts without 5-level nested page tables. Guest firmware
is expected to use the information when mapping BARs; this avoids
that they end up at a legal, but unmappable, GPA.
- Fixed a bug where KVM would not reject accesses to MSR that aren't
supposed to exist given the vCPU model and/or KVM configuration.
- As usual, a bunch of code cleanups.
x86 (AMD):
- Implement a new and improved API to initialize SEV and SEV-ES VMs,
which will also be extendable to SEV-SNP.
The new API specifies the desired encryption in KVM_CREATE_VM and
then separately initializes the VM. The new API also allows
customizing the desired set of VMSA features; the features affect
the measurement of the VM's initial state, and therefore enabling
them cannot be done tout court by the hypervisor.
While at it, the new API includes two bugfixes that couldn't be
applied to the old one without a flag day in userspace or without
affecting the initial measurement. When a SEV-ES VM is created with
the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are rejected
once the VMSA has been encrypted. Also, the FPU and AVX state will
be synchronized and encrypted too.
- Support for GHCB version 2 as applicable to SEV-ES guests.
This, once more, is only accessible when using the new
KVM_SEV_INIT2 flow for initialization of SEV-ES VMs.
x86 (Intel):
- An initial bunch of prerequisite patches for Intel TDX were merged.
They generally don't do anything interesting. The only somewhat
user visible change is a new debugging mode that checks that KVM's
MMU never triggers a #VE virtualization exception in the guest.
- Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig
VM-Exit to L1, as per the SDM.
Generic:
- Use vfree() instead of kvfree() for allocations that always use
vcalloc() or __vcalloc().
- Remove .change_pte() MMU notifier - the changes to non-KVM code are
small and Andrew Morton asked that I also take those through the
KVM tree.
The callback was only ever implemented by KVM (which was also the
original user of MMU notifiers) but it had been nonfunctional ever
since calls to set_pte_at_notify were wrapped with
invalidate_range_start and invalidate_range_end... in 2012.
Selftests:
- Enhance the demand paging test to allow for better reporting and
stressing of UFFD performance.
- Convert the steal time test to generate TAP-friendly output.
- Fix a flaky false positive in the xen_shinfo_test due to comparing
elapsed time across two different clock domains.
- Skip the MONITOR/MWAIT test if the host doesn't actually support
MWAIT.
- Avoid unnecessary use of "sudo" in the NX hugepage test wrapper
shell script, to play nice with running in a minimal userspace
environment.
- Allow skipping the RSEQ test's sanity check that the vCPU was able
to complete a reasonable number of KVM_RUNs, as the assert can fail
on a completely valid setup.
If the test is run on a large-ish system that is otherwise idle,
and the test isn't affined to a low-ish number of CPUs, the vCPU
task can be repeatedly migrated to CPUs that are in deep sleep
states, which results in the vCPU having very little net runtime
before the next migration due to high wakeup latencies.
- Define _GNU_SOURCE for all selftests to fix a warning that was
introduced by a change to kselftest_harness.h late in the 6.9
cycle, and because forcing every test to #define _GNU_SOURCE is
painful.
- Provide a global pseudo-RNG instance for all tests, so that library
code can generate random, but determinstic numbers.
- Use the global pRNG to randomly force emulation of select writes
from guest code on x86, e.g. to help validate KVM's emulation of
locked accesses.
- Allocate and initialize x86's GDT, IDT, TSS, segments, and default
exception handlers at VM creation, instead of forcing tests to
manually trigger the related setup.

- Fix a goof in the KVM_CREATE_GUEST_MEMFD documentation"

Pull CXL updates from Dave Jiang:
- Three CXL mailbox passthrough commands are added to support the
populating and clearing of vendor debug logs:
- Get Log Capabilities
- Get Supported Log Sub-List Commands
- Clear Log
- Add support of Device Phyiscal Address (DPA) to Host Physical Address
(HPA) translation for CXL events of cxl_dram and cxl_general media.
This allows user space to figure out which CXL region the event
occured via trace event.
- Connect CXL to CPER reporting.
If a device is configured for firmware first, CXL event records are
not sent directly to the host. Those records are reported through EFI
Common Platform Error Records (CPER). Add support to route the CPER
records through the CXL sub-system in order to provide DPA to HPA
translation and also event decoding and tracing. This is useful for
users to determine which system issues may correspond to specific
hardware events.
- A number of misc cleanups and fixes:
- Fix for compile warning of cxl_security_ops
- Add debug message for invalid interleave granularity
- Enhancement to cxl-test event testing
- Add dev_warn() on unsupported mixed mode decoder
- Fix use of phys_to_target_node() for x86

"Finally something fun. Mike Rapoport does some cleanup to allow us to
take out module_alloc() out of modules into a new paint shedded
execmem_alloc() and execmem_free() so to make emphasis these helpers
are actually used outside of modules.
It starts with a non-functional changes API rename / placeholders to
then allow architectures to define their requirements into a new shiny
struct execmem_info with ranges, and requirements for those ranges.
Archs now can intitialize this execmem_info as the last part of
mm_core_init() if they have to diverge from the norm. Each range is a
known type clearly articulated and spelled out in enum execmem_type.
Although a lot of this is major cleanup and prep work for future

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd
passing functionality. New method based on Tarjan's Strongly
Connected Components algorithm should be both faster and remove a
lot of workarounds we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP
packets and forwarding them together. Useful for small switches /
routers which lack basic checksum offload in some scenarios (e.g.
PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't use
NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6
address labels, netdev threaded NAPI sysfs files, bonding driver's
sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics,
TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot
of the link information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory
accounting, RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2%
PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol
driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states. State can be
used either for input or output packet processing.
Things we sprinkled into general kernel code:
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter:
- Use GFP_KERNEL to clone elements, to deal better with OOM
situations and avoid failures in the .commit step.
BPF:
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function
entry and return, the entry program can decide if the return
program gets executed and the entry program can share u64 cookie
value with return program. "Session mode" is a common use-case for
tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw
tracepoint programs in order to ease migration from classic to raw
tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V
JITs. This allows inlining functions which need to access per-CPU
state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86
instruction. Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor
process-context bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto
APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API:
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by
rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line)
config.
- Initial bits of a queue control API, for now allowing a single
queue to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling:
- Remove the need to create a config file to run the net forwarding
tests so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test
machine). Add a few such tests.
- Create a shared code library for writing Python tests. Expose the
YAML Netlink library from tools/ to the tests for easy Netlink
access.
- Move netfilter tests under net/, extend them, separate performance
tests from correctness tests, and iron out issues found by running
them "on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF
info, TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers:
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application
rather than dmesg (large number of driver changes from Asbjørn
Sloth Tønnesen).
- Ethernet high-speed NICs:
- Broadcom (bnxt):
- support multiple RSS contexts and steering traffic to them
- support XDP metadata
- make page pool allocations more NUMA aware
- Intel (100G, ice, idpf):

Pull firewire updates from Takashi Sakamoto:
"During the development period of v6.8 kernel, it became evident that
there was a lack of helper utilities to trace the initial state of
bus, while investigating certain PHYs compliant with different
versions of IEEE 1394 specification.
This series of changes includes the addition of tracepoints events,
provided by 'firewire' subsystem. These events enable tracing of how
firewire core functions during bus reset and asynchronous
communication over IEEE 1394 bus.
When implementing the tracepoints events, it was found that the
existing serialization and deserialization helpers for several types
of asynchronous packets are scattered across both firewire-core and
firewire-ohci kernel modules. A set of inline functions is newly added
to address it, along with some KUnit tests, serving as the foundation
for the tracepoints events. This renders the dispersed code obsolete.
The remaining changes constitute the final steps in phasing out the
usage of deprecated PCI MSI APIs, in continuation from the previous
version"

Pull dlm updates from David Teigland:
"This set includes some small fixes, and some big internal changes:
- Fix a long standing race between the unlock callback for the last
lkb struct, and removing the rsb that became unused after the final
unlock. This could lead different nodes to inconsistent info about
the rsb master node.
- Remove unnecessary refcounting on callback structs, returning to
the way things were done in the past.
- Do message processing in softirq context. This allows dlm messages
to be cleared more quickly and efficiently, reducing long lists of
incomplete requests. A future change to run callbacks directly from
this context will make this more effective.
- The softirq message processing involved a number of patches
changing mutexes to spinlocks and rwlocks, and a fair amount of
code re-org in preparation.
- Use an rhashtable for rsb structs, rather than our old internal
hash table implementation. This also required some re-org of lists
and locks preparation for the change.
- Drop the dlm_scand kthread, and use timers to clear unused rsb
structs. Scanning all rsb's periodically was a lot of wasted work.
- Fix recent regression in logic for copying LVB data in user space

Pull btrfs updates from David Sterba:
"This update brings a few minor performance improvements, otherwise
there's a lot of refactoring, cleanups and other sort of not user
visible changes.
Performance improvements:
- inline b-tree locking functions, improvement in metadata-heavy
changes
- relax locking on a range that's being reflinked, allows read
operations to run in parallel
- speed up NOCOW write checks (throughput +9% on a sample test)
- extent locking ranges have been reduced in several places, namely
around delayed ref processing
Core:
- more page to folio conversions:
- relocation
- send
- compression
- inline extent handling
- super block write and wait
- extent_map structure optimizations:
- reduced structure size
- code simplifications
- add shrinker for allocated objects, the numbers can go high and
could exhaust memory on smaller systems (reported) as they may
not get an opportunity to be freed fast enough
- extent locking optimizations:
- reduce locking ranges where it does not seem to be necessary and
are safe due to other means of synchronization
- potential improvements due to lower contention,
allocation/freeing and state management operations of extent
state tracking structures
- delayed ref cleanups and simplifications
- updated trace points
- improved error handling, warnings and assertions
- cleanups and refactoring, unification of error handling paths"

Pull gpio updates from Bartosz Golaszewski
"This was a quiet release cycle for the GPIO tree and so this
pull-request is relatively small.
We have one new driver, some minor improvements to the GPIO core code
and across several drivers, some DT and documentation updates but in
general nothing stands out or is controversial. All changes have spent
time in next with no reported issues (or ones that were quickly
fixed).
GPIO core:
- remove more unused legacy interfaces (after converting the last
remaining users to better alternatives)
- update kerneldocs
- improve error handling and log messages in GPIO ACPI code
- remove dead code (always true checks) from GPIOLIB
New drivers:
- add a driver for Intel Granite Rapids-D vGPIO
Driver improvements:
- use -ENOTSUPP consistently in gpio-regmap and gpio-pcie-idio-24
- provide an ID table for gpio-cros-ec to avoid a driver name
fallback check
- add support for gpio-ranges for GPIO drivers supporting multiple
GPIO banks
- switch to using dynamic GPIO base in gpio-brcmstb
- fix irq handling in gpio-npcm-sgpio
- switch to memory mapped IO accessors in gpio-sch
DT bindings:
- add support for gpio-ranges to gpio-brcmstb
- add support for a new model and the gpio-line-names property to
gpio-mpfs
Documentation:
- replace leading tabs with spaces in code blocks
- fix typos"

Pull pwm updates from Uwe Kleine-König:
"Apart for the normal updates for dt bindings, cleanups and support for
new device variants to existing drivers this completes the conversion
to pwmchip_alloc() which was started in the v6.9 development cycle.
Using pwmchip_alloc() is a precondition to the character device
support which allows easier and faster access to PWM devices. However
there are some issues I want to clean up before including it in
mainline, so this isn't contained here despite it was in next for some
time.
Thanks to Alexandre Mergnat, Binbin Zhou, Dmitry Rokosov, George
Stark, Jerome Brunet and Varshini Rajendran for their contributions.
Further thanks go to AngeloGioacchino Del Regno, Conor Dooley, David
Lechner, Fabrice Gasnier, Florian Fainelli, Guenter Roeck, Gustavo A.
R. Silva, Krzysztof Kozlowski and Rob Herring for valuable patch
review"
