582a1ef360 RTLA patches for v7.0 
- Remove unused function declarations
 
   Some functions were removed in recent code consolidation 6.18, but
   their prototypes were not removed from headers. Remove them.
 
 - Set stop threshold after enabling instances
 
   Prefer recording samples without stopping on them on the start of
   tracing to stopping on samples that are never recorded. This fixes
   flakiness of some RTLA tests and unifies behavior of sample collection
   between tracefs mode and BPF mode.
 
 - Consolidate usage help message implementation
 
   RTLA tools (osnoise-top, osnoise-hist, timerlat-top, timerlat-hist)
   each implement usage help individually. Move common logic between
   them into a new function to reduce code duplication.
 
 - Add BPF actions feature
 
   Add option --bpf-action to attach a BPF program (passed as filename of
   its ELF representation) to be executed via BPF tail call at latency
   threshold.
 
 - Consolidate command line option parsing
 
   Each RTLA tool implements the parsing of command line options
   individually. Now that we have a common structure for parameters,
   unify the parsing of those options common among all four tools into
   one function.
 
 - De-duplicate cgroup common code
 
   Two functions in utils.c, setting cgroup for comm and setting cgroup
   for pid, duplicate code for constructing the cgroup path. Extract it
   to a new helper function.
 
 - String and error handling fixes and cleanups
 
   There were several instances of unsafe string and error handling that
   could cause invalid memory access; fix them. Also, remove a few unused
   headers, update .gitignore, and deduplicate code.

f75c03a761 runtime verifier changes for 7.0: 
- Refactor da_monitor to minimise macros
 
   Complete refactor of da_monitor.h to reduce reliance on macros
   generating functions. Use generic static functions and uses the
   preprocessor only when strictly necessary (e.g. for tracepoint
   handlers).
 
   The change essentially relies on functions with generic names (e.g.
   da_handle) instead of monitor-specific as well adding the need to
   define constant (e.g. MONITOR_NAME, MONITOR_TYPE) before including the
   header rather than calling macros that would define functions.
   Also adapt monitors and documentation accordingly.
 
 - Cleanup DA code generation scripts
 
   Clean up functions in dot2c removing reimplementations of trivial
   library functions (__buff_to_string) and removing some other unused
   intermediate steps.
 
 - Annotate functions with types in the rvgen python scripts
 
 - Remove superfluous assignments and cleanup generated code
 
   The rvgen scripts generate a superfluous assignment to 0 for enum
   variables and don't add commas to the last elements, which is against
   the kernel coding standards. Change the generation process for a
   better compliance and slightly simpler logic.
 
 - Remove superfluous declarations from generated code
 
   The monitor container source files contained a declaration and a
   definition for the rv_monitor variable. The former is superfluous and
   was removed.
 
 - Fix reference to outdated documentation

  - Adds device tree configurations for De0 Nano single and
    multicore configurations.
  - Fixes bug in OpenRISC SMP preventing the kernel from running on FPGA
    boards, due to IPIs not being unmasked on secondary CPUs in some
    configurations.

5903c871e2 New features and improvements for the ext4 file system 
* Avoid unnecessary cache invadiation in the extent status cache
     (es_cache) when adding extents to be cached in the es_cache and we
     are not changing the extent tree.
   * Add a sysfs parameter, err_report_sec, to control how frequently
     to log a warning message that file system inconsistency has been
     detected.  (Previously we logged the warning message every 24
     hours.)
   * Avoid unnecessary forced ordered writes when appending to a file
     when delayed allocation is enabled.
   * Defer splitting unwritten extents to I/O completion to improve
     write performance of concurrent direct I/O writes to multiple
     files.
   * Refactor and add kunit tests to the extent splitting and
     conversion code paths.
 
 Various Bug Fixes
 
   * Fix a panic when the debugging DOUBLE_CHECK macro is defined.
   * Avoid using fast commit for rare and complex file system
     operations to make fast commit easier to reason about.  This can
     also avoid some corner cases that could result in file system
     inconsistency if there is a crash between the fast commit before a
     subsequent full commit.
   * Fix memory leaks in error paths
   * Fix a false positive reports caused when running stress tests
     using mixed huge-page workloads caused by a race between page
     migration and bitmap updates.
   * Fix a potential recursion into file system reclaim when evicting
     an inode when fast commit is enabled.
   * Fix a warning caused by a potential double decrement to the dirty
     clusters counter when executing FS_IOC_SHUTDOWN when running a
     stress test.
   * Enable mballoc optimzied scanning regardless whether the inode is
     using indirect blocks or extent trees to map blocks.

2831fa8b8b NFSD 7.0 Release Notes 
Neil Brown and Jeff Layton contributed a dynamic thread pool sizing
 mechanism for NFSD. The sunrpc layer now tracks minimum and maximum
 thread counts per pool, and NFSD adjusts running thread counts based
 on workload: idle threads exit after a timeout when the pool exceeds
 its minimum, and new threads spawn automatically when all threads
 are busy. Administrators control this behavior via the nfsdctl
 netlink interface.
 
 Rick Macklem, FreeBSD NFS maintainer, generously contributed server-
 side support for the POSIX ACL extension to NFSv4, as specified in
 draft-ietf-nfsv4-posix-acls. This extension allows NFSv4 clients to
 get and set POSIX access and default ACLs using native NFSv4
 operations, eliminating the need for sideband protocols. The feature
 is gated by a Kconfig option since the IETF draft has not yet been
 ratified.
 
 Chuck Lever delivered numerous improvements to the xdrgen tool.
 Error reporting now covers parsing, AST transformation, and invalid
 declarations. Generated enum decoders validate incoming values
 against valid enumerator lists. New features include pass-through
 line support for embedding C directives in XDR specifications,
 16-bit integer types, and program number definitions. Several code
 generation issues were also addressed.
 
 When an administrator revokes NFSv4 state for a filesystem via the
 unlock_fs interface, ongoing async COPY operations referencing that
 filesystem are now cancelled, with CB_OFFLOAD callbacks notifying
 affected clients.
 
 The remaining patches in this pull request are clean-ups and minor
 optimizations. Sincere thanks to all contributors, reviewers,
 testers, and bug reporters who participated in the v7.0 NFSD
 development cycle.

37a93dd5c4 Networking changes for 7.0 
Core & protocols
 ----------------
 
  - A significant effort all around the stack to guide the compiler to
    make the right choice when inlining code, to avoid unneeded calls for
    small helper and stack canary overhead in the fast-path. This
    generates better and faster code with very small or no text size
    increases, as in many cases the call generated more code than the
    actual inlined helper.
 
  - Extend AccECN implementation so that is now functionally complete,
    also allow the user-space enabling it on a per network namespace
    basis.
 
  - Add support for memory providers with large (above 4K) rx buffer.
    Paired with hw-gro, larger rx buffer sizes reduce the number of
    buffers traversing the stack, dincreasing single stream CPU usage by
    up to ~30%.
 
  - Do not add HBH header to Big TCP GSO packets. This simplifies the RX
    path, the TX path and the NIC drivers, and is possible because
    user-space taps can now interpret correctly such packets without the
    HBH hint.
 
  - Allow IPv6 routes to be configured with a gateway address that is
    resolved out of a different interface than the one specified, aligning
    IPv6 to IPv4 behavior.
 
  - Multi-queue aware sch_cake. This makes it possible to scale the rate
    shaper of sch_cake across multiple CPUs, while still enforcing a
    single global rate on the interface.
 
  - Add support for the nbcon (new buffer console) infrastructure to
    netconsole, enabling lock-free, priority-based console operations that
    are safer in crash scenarios.
 
  - Improve the TCP ipv6 output path to cache the flow information, saving
    cpu cycles, reducing cache line misses and stack use.
 
  - Improve netfilter packet tracker to resolve clashes for most protocols,
    avoiding unneeded drops on rare occasions.
 
  - Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
 
  - Reduce tcp socket size by one cache line.
 
  - Notify neighbour changes atomically, avoiding inconsistencies between
    the notification sequence and the actual states sequence.
 
  - Add vsock namespace support, allowing complete isolation of vsocks
    across different network namespaces.
 
  - Improve xsk generic performances with cache-alignment-oriented
    optimizations.
 
  - Support netconsole automatic target recovery, allowing netconsole
    to reestablish targets when underlying low-level interface comes back
    online.
 
 Driver API
 ----------
 
  - Support for switching the working mode (automatic vs manual) of a DPLL
    device via netlink.
 
  - Introduce PHY ports representation to expose multiple front-facing
    media ports over a single MAC.
 
  - Introduce "rx-polarity" and "tx-polarity" device tree properties, to

         - ath12k: a significant driver refactor to support multi-wiphy
           devices and and pave the way for future device support in the
           same driver (rather than splitting to ath13k)
         - ath12k: support for the QCC2072 chipset
      - Intel:

098b6e44cb Devicetree updates for v7.0: 
DT core:
 - Sync dtc/libfdt with upstream v1.7.2-62-ga26ef6400bd8
 
 - Add a for_each_compatible_node_scoped() loop and convert users in
   cpufreq, dmaengine, clk, cdx, powerpc and Arm
 
 - Simplify of/platform.c with scoped loop helpers
 
 - Add fw_devlink tracking for "mmc-pwrseq"
 
 - Optimize fw_devlink callback code size for pinctrl-N properties
 
 - Replace strcmp_suffix() with strends()
 
 DT bindings:
 - Support building single binding targets
 
 - Convert google,goldfish-fb, cznic,turris-mox-rwtm, ti,prm-inst
 
 - Add bindings for Freescale AVIC, Realtek RTD1xxx system controllers,
   Microchip 25AA010A EEPROM, OnSemi FIN3385, IEI WT61P803 PUZZLE, Delta
   Electronics DPS-800-AB power supply, Infineon IR35221 Digital
   Multi-phase Controller, Infineon PXE1610 Digital Dual Output 6+1
   VR12.5 & VR13 CPU Controller, socionext,uniphier-smpctrl, and
   xlnx,zynqmp-firmware
 
 - Lots of trivial binding fixes to address warnings in DTS files. These
   are mostly for arm64 platforms which is getting closer to be warning
   free. Some public shaming has helped.

c6e62d002b Driver core changes for 7.0-rc1 
- 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()

   - 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

       This enables higher-level concepts such as register abstractions,

       In a first step, introduce the Io, IoCapable<T>, and IoKnownSize

Merge tag 'pci-v7.0-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Don't try to enable Extended Tags on VFs since that bit is Reserved
     and causes misleading log messages (Håkon Bugge)

   - Initialize Endpoint Read Completion Boundary to match Root Port,
     regardless of ACPI _HPX (Håkon Bugge)

   - Apply _HPX PCIe Setting Record only to AER configuration, and only
     when OS owns PCIe hotplug but not AER, to avoid clobbering Extended
     Tag and Relaxed Ordering settings (Håkon Bugge)

  Resource management:

   - Move CardBus code to setup-cardbus.c and only build it when
     CONFIG_CARDBUS is set (Ilpo Järvinen)

   - Fix bridge window alignment with optional resources, where
     additional alignment requirement was previously lost (Ilpo
     Järvinen)

   - Stop over-estimating bridge window size since they are now assigned
     without any gaps between them (Ilpo Järvinen)

   - Increase resource MAX_IORES_LEVEL to avoid /proc/iomem flattening
     for nested bridges and endpoints (Ilpo Järvinen)

   - Add pbus_mem_size_optional() to handle sizes of optional resources
     (SR-IOV VF BARs, expansion ROMs, bridge windows) (Ilpo Järvinen)

   - Don't claim disabled bridge windows to avoid spurious claim
     failures (Ilpo Järvinen)

  Driver binding:

   - Fix device reference leak in pcie_port_remove_service() (Uwe
     Kleine-König)

   - Move pcie_port_bus_match() and pcie_port_bus_type to PCIe-specific
     portdrv.c (Uwe Kleine-König)

   - Convert portdrv to use pcie_port_bus_type.probe() and .remove()
     callbacks so .probe() and .remove() can eventually be removed from
     struct device_driver (Uwe Kleine-König)

  Error handling:

   - Clear stale errors on reporting agents upon probe so they don't
     look like recent errors (Lukas Wunner)

   - Add generic RAS tracepoint for hotplug events (Shuai Xue)

   - Add RAS tracepoint for link speed changes (Shuai Xue)

  Power management:

   - Avoid redundant delay on transition from D3hot to D3cold if the
     device was already in D3hot (Brian Norris)

   - Prevent runtime suspend until devices are fully initialized to
     avoid saving incompletely configured device state (Brian Norris)

  Power control:

   - Add power_on/off callbacks with generic signature to pwrseq,
     tc9563, and slot drivers so they can be used by pwrctrl core
     (Manivannan Sadhasivam)

   - Add PCIe M.2 connector support to the slot pwrctrl driver
     (Manivannan Sadhasivam)

   - Switch to pwrctrl interfaces to create, destroy, and power on/off
     devices, calling them from host controller drivers instead of the
     PCI core (Manivannan Sadhasivam)

   - Drop qcom .assert_perst() callbacks since this is now done by the
     controller driver instead of the pwrctrl driver (Manivannan
     Sadhasivam)

  Virtualization:

   - Remove an incorrect unlock in pci_slot_trylock() error handling
     (Jinhui Guo)

   - Lock the bridge device for slot reset (Keith Busch)

   - Enable ACS after IOMMU configuration on OF platforms so ACS is
     enabled an all devices; previously the first device enumerated
     (typically a Root Port) didn't have ACS enabled (Manivannan
     Sadhasivam)

   - Disable ACS Source Validation for IDT 0x80b5 and 0x8090 switches to
     work around hardware erratum; previously ACS SV was only
     temporarily disabled, which worked for enumeration but not after
     reset (Manivannan Sadhasivam)

  Peer-to-peer DMA:

   - Release per-CPU pgmap ref when vm_insert_page() fails to avoid hang
     when removing the PCI device (Hou Tao)

   - Remove incorrect p2pmem_alloc_mmap() warning about page refcount
     (Hou Tao)

  Endpoint framework:

   - Add configfs sub-groups synchronously to avoid NULL pointer
     dereference when racing with removal (Liu Song)

   - Fix swapped parameters in pci_{primary/secondary}_epc_epf_unlink()
     functions (Manikanta Maddireddy)

  ASPEED PCIe controller driver:

   - Add ASPEED Root Complex DT binding and driver (Jacky Chou)

  Freescale i.MX6 PCIe controller driver:

   - Add DT binding and driver support for an optional external refclock
     in addition to the refclock from the internal PLL (Richard Zhu)

   - Fix CLKREQ# control so host asserts it during enumeration and
     Endpoints can use it afterwards to exit the L1.2 link state
     (Richard Zhu)

  NVIDIA Tegra PCIe controller driver:

   - Export irq_domain_free_irqs() to allow PCI/MSI drivers that tear
     down MSI domains to be built as modules (Aaron Kling)

   - Allow pci-tegra to be built as a module (Aaron Kling)

  NVIDIA Tegra194 PCIe controller driver:

   - Relax Kconfig so tegra194 can be built for platforms beyond
     Tegra194 (Vidya Sagar)

  Qualcomm PCIe controller driver:

   - Merge SC8180x DT binding into SM8150 (Krzysztof Kozlowski)

   - Move SDX55, SDM845, QCS404, IPQ5018, IPQ6018, IPQ8074 Gen3,
     IPQ8074, IPQ4019, IPQ9574, APQ8064, MSM8996, APQ8084 to dedicated
     schema (Krzysztof Kozlowski)

   - Add DT binding and driver support for SA8255p Endpoint being
     configured by firmware (Mrinmay Sarkar)

   - Parse PERST# from all PCIe bridge nodes for future platforms that
     will have PERST# in Switch Downstream Ports as well as in Root
     Ports (Manivannan Sadhasivam)

  Renesas RZ/G3S PCIe controller driver:

   - Use pci_generic_config_write() since the writability provided by
     the custom wrapper is unnecessary (Claudiu Beznea)

  SOPHGO PCIe controller driver:

   - Disable ASPM L0s and L1 on Sophgo 2044 PCIe Root Ports (Inochi
     Amaoto)

  Synopsys DesignWare PCIe controller driver:

   - Extend PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() to return a
     pointer to the preceding Capability, to allow removal of
     Capabilities that are advertised but not fully implemented (Qiang
     Yu)

   - Remove MSI and MSI-X Capabilities in platforms that can't support
     them, so the PCI core automatically falls back to INTx (Qiang Yu)

   - Add ASPM L1.1 and L1.2 Substates context to debugfs ltssm_status
     for drivers that support this (Shawn Lin)

   - Skip PME_Turn_Off broadcast and L2/L3 transition during suspend if
     link is not up to avoid an unnecessary timeout (Manivannan
     Sadhasivam)

   - Revert dw-rockchip, qcom, and DWC core changes that used link-up
     IRQs to trigger enumeration instead of waiting for link to be up
     because the PCI core doesn't allocate bus number space for
     hierarchies that might be attached (Niklas Cassel)

   - Make endpoint iATU entry for MSI permanent instead of programming
     it dynamically, which is slow and racy with respect to other
     concurrent traffic, e.g., eDMA (Koichiro Den)

   - Use iMSI-RX MSI target address when possible to fix endpoints using
     32-bit MSI (Shawn Lin)

   - Allow DWC host controller driver probe to continue if device is not
     found or found but inactive; only fail when there's an error with
     the link (Manivannan Sadhasivam)

   - For controllers like NXP i.MX6QP and i.MX7D, where LTSSM registers
     are not accessible after PME_Turn_Off, simply wait 10ms instead of
     polling for L2/L3 Ready (Richard Zhu)

   - Use multiple iATU entries to map large bridge windows and DMA
     ranges when necessary instead of failing (Samuel Holland)

   - Add EPC dynamic_inbound_mapping feature bit for Endpoint
     Controllers that can update BAR inbound address translation without
     requiring EPF driver to clear/reset the BAR first, and advertise it
     for DWC-based Endpoints (Koichiro Den)

   - Add EPC subrange_mapping feature bit for Endpoint Controllers that
     can map multiple independent inbound regions in a single BAR,
     implement subrange mapping, advertise it for DWC-based Endpoints,
     and add Endpoint selftests for it (Koichiro Den)

   - Make resizable BARs work for Endpoint multi-PF configurations;
     previously it only worked for PF 0 (Aksh Garg)

   - Fix Endpoint non-PF 0 support for BAR configuration, ATU mappings,
     and Address Match Mode (Aksh Garg)

   - Set up iATU when ECAM is enabled; previously IO and MEM outbound
     windows weren't programmed, and ECAM-related iATU entries weren't
     restored after suspend/resume, so config accesses failed (Krishna
     Chaitanya Chundru)

  Miscellaneous:

   - Use system_percpu_wq and WQ_PERCPU to explicitly request per-CPU
     work so WQ_UNBOUND can eventually be removed (Marco Crivellari)"

Merge tag 'slab-for-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

Pull slab updates from Vlastimil Babka:

 - The percpu sheaves caching layer was introduced as opt-in in 6.18 and
   now we enable it for all caches and remove the previous cpu (partial)
   slab caching mechanism.

   Besides the lower locking overhead and much more likely fastpath when
   freeing, this removes the rather complicated code related to the cpu
   slab lockless fastpaths (using this_cpu_try_cmpxchg128/64) and all
   its complications for PREEMPT_RT or kmalloc_nolock().

   The lockless slab freelist+counters update operation using
   try_cmpxchg128/64 remains and is crucial for freeing remote NUMA
   objects, and to allow flushing objects from sheaves to slabs mostly
   without the node list_lock (Vlastimil Babka)

 - Eliminate slabobj_ext metadata overhead when possible. Instead of
   using kmalloc() to allocate the array for memcg and/or allocation
   profiling tag pointers, use leftover space in a slab or per-object
   padding due to alignment (Harry Yoo)

 - Various followup improvements to the above (Hao Li)

38ef046544 sched_ext: Changes for v6.20 
- Move C example schedulers back from the external scx repo to
   tools/sched_ext as the authoritative source. scx_userland and scx_pair
   are returning while scx_sdt (BPF arena-based task data management) is
   new. These schedulers will be dropped from the external repo.

   creation fails across all in-tree schedulers.
 
 - Avoid redundant irq_work_queue() calls in destroy_dsq() by only

1e83ccd592 sched/mmcid: Don't assume CID is CPU owned on mode switch 
Shinichiro reported a KASAN UAF, which is actually an out of bounds access
in the MMCID management code.

   CPU0						CPU1
   						T1 runs in userspace
   T0: fork(T4) -> Switch to per CPU CID mode
         fixup() set MM_CID_TRANSIT on T1/CPU1
   T4 exit()
   T3 exit()
   T2 exit()
						T1 exit() switch to per task mode
						 ---> Out of bounds access.

As T1 has not scheduled after T0 set the TRANSIT bit, it exits with the
TRANSIT bit set. sched_mm_cid_remove_user() clears the TRANSIT bit in
the task and drops the CID, but it does not touch the per CPU storage.
That's functionally correct because a CID is only owned by the CPU when
the ONCPU bit is set, which is mutually exclusive with the TRANSIT flag.

Now sched_mm_cid_exit() assumes that the CID is CPU owned because the
prior mode was per CPU. It invokes mm_drop_cid_on_cpu() which clears the
not set ONCPU bit and then invokes clear_bit() with an insanely large
bit number because TRANSIT is set (bit 29).

Prevent that by actually validating that the CID is CPU owned in
mm_drop_cid_on_cpu().

d061251387 sound updates for 7.0-rc1 
It's been relatively calm for a new era; majority of changes are for
 ASoC, mostly device-specific changes, while there are a bit of
 cleanups in core stuff.  A few SPI API and regmap updates are included
 to be used by sound drivers, too.
 
 Core:
 - A few trivial cleanups about __free() and runtime PM macros
 - Convert to new snd_seq_bus binding
 
 ASoC:
 - Generic SDCA support for reporting jack events
 - Continuing platform support, cleanup and feature improvements for
   AMD, Intel, Qualcomm and SOF code
 - Platform description improvements for the Cirrus drivers
 - Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo
   CV1800B
 
 HD- and USB-audio:
 - Many quirks as usual

0d6dd4738d firewire updates for v7.0 
This update includes the following changes.
 
  - Refactor page allocation dedicated to 1394 OHCI IR/IT/AR DMA contexts
 
    Although 1394 OHCI specification does not impose any restriction on
    the memory size dedicated to these DMA contexts, 1394 OHCI PCI driver
    allocates pages for convenience when mapping them into either kernel
    space or userspace VMA. The driver previously used dma_alloc_pages()
    for both page allocation and mapping creation, even though this kernel
    API is rarely used. Following discussions questioning the page-oriented
    kernel API in the DMA layer, the driver has been refactored to avoid
    using this API. In addition, the use of private members in the
    allocated pages has been removed following long-standing concern.
 
  - Allocate variable-sized buffer for isochronous context header
 
    1394 OHCI PCI driver previously allocated a single page for isochronous
    context header. As a result, the buffer size for the header was fixed
    to PAGE_SIZE, which imposed a limitation on IEC 61883-1/6 packet
    streaming engine. Consequently, the ALSA PCM devices provided by
    drivers for audio and music units in IEEE 1394 bus were constrained in
    the maximum size of buffer period (64 ms in most cases). This limitation
    is resolved by dynamically allocating the header buffer with an
    arbitrary size.

 just a few cleanups and a single fix for the tiehrpwm driver that came
 in too late for making it into v6.19.

e86dda7bde spi: Updates for v7.0 
The highlight here is that David Lechner has added support for multi-lane
 SPI devices.  Unlike the existing dual/quad SPI support this is for
 devices (typically ADCs/DACs) which support multiple independent data
 streams over multiple data lanes, instead of sending one data stream N
 times as fast they simultaneously transfer N different data streams.
 This is very similar to the case where multiple devices are grouped
 together but in this case it's a single device in a way that's visible
 to software.
 
 Otherwise there's been quite a bit of work on existing drivers, both
 cleanup and feature improvement, and a reasonable collection of new
 drivers.
 
  - Support for multi-lane SPI devices.
  - Preparatory work for some memory mapped flash improvements that will
    happen in the MTD subsystem.
  - Several conversions to fwnode APIs.
  - A bunch of cleanup and hardening work on the ST drivers.
  - Support for DMA mode on Renesas RZV2H and i.MX target mode.
  - Support for ATCSPI200, AXIADO AX300, NXP XPI and Renesas RZ/N1.

f6c42489fe regulator: Updates for v7.0 
There's a bunch of new drivers here, plus a lot of hardening for the
 supply resolution code which allow us to support systems where we have
 two PMICs each of which has regulators supplied by the other.  This did
 work a long time ago but got broken as part of improved integration with
 the device model, it's fairly rare so nobody noticed.
 
  - Improvements for supply handling from André Draszik to allow systems
    with two PMICs with supply/consumer relationships in both
    directions to instantiate.
  - New drivers for Maxim MAX776750, Realtek RT8902, Samsung S2MPG11,
    Texas Instuments TPS65185.
 
 This have also pulls in some MFD updates which are build dependencies
 for the Samsung S2MPG11 support.

Pull regulator updates from Mark Brown:
 "There's a bunch of new drivers here, plus a lot of hardening for the
  supply resolution code which allow us to support systems where we have
  two PMICs each of which has regulators supplied by the other. This did
  work a long time ago but got broken as part of improved integration
  with the device model, it's fairly rare so nobody noticed.

   - Improvements for supply handling from André Draszik to allow
     systems with two PMICs with supply/consumer relationships in both
     directions to instantiate.

   - New drivers for Maxim MAX776750, Realtek RT8902, Samsung S2MPG11,
     Texas Instuments TPS65185.

  This have also pulls in some MFD updates which are build dependencies
  for the Samsung S2MPG11 support"

d5cbd9f332 regmap: Updates for v7.0 
The main change here is the implementation of a mechanism for generating
 register defaults via a callback rather than with a table in the driver.
 This is useful for devices where there are large ranges of registers
 with the same or generateable values, it allows us to have a small
 amount of code instead of a larger amount of default data.

42d1c54d62 bnge/bng_re: Add a new HSI 
The HSI is shared between the firmware and the driver and is
automatically generated.
Add a new HSI for the BNGE driver. The current HSI refers to BNXT,
which will become incompatible with ThorUltra devices as the
BNGE driver adds more features. The BNGE driver will not use the HSI
located in the bnxt folder.
Also, add an HSI for ThorUltra RoCE driver.

bf9cf80cab net: macb: Fix tx/rx malfunction after phy link down and up 
In commit 99537d5c47 ("net: macb: Relocate mog_init_rings() callback
from macb_mac_link_up() to macb_open()"), the mog_init_rings() callback
was moved from macb_mac_link_up() to macb_open() to resolve a deadlock
issue. However, this change introduced a tx/rx malfunction following
phy link down and up events. The issue arises from a mismatch between
the software queue->tx_head, queue->tx_tail, queue->rx_prepared_head,
and queue->rx_tail values and the hardware's internal tx/rx queue
pointers.

According to the Zynq UltraScale TRM [1], when tx/rx is disabled, the
internal tx queue pointer resets to the value in the tx queue base
address register, while the internal rx queue pointer remains unchanged.
The following is quoted from the Zynq UltraScale TRM:
  When transmit is disabled, with bit [3] of the network control register
  set low, the transmit-buffer queue pointer resets to point to the address
  indicated by the transmit-buffer queue base address register. Disabling
  receive does not have the same effect on the receive-buffer queue
  pointer.

Additionally, there is no need to reset the RBQP and TBQP registers in a
phy event callback. Therefore, move macb_init_buffers() to macb_open().
In a phy link up event, the only required action is to reset the tx
software head and tail pointers to align with the hardware's behavior.

e3998b6e90 net: ti: icssg-prueth: Add optional dependency on HSR 
Commit 95540ad674 ("net: ti: icssg-prueth: Add support for HSR frame
forward offload") introduced support for offloading HSR frame forwarding,
which relies on functions such as is_hsr_master() provided by the HSR
module. Although HSR provides stubs for configurations with HSR
disabled, this driver still requires an optional dependency on HSR.
Otherwise, build failures will occur when icssg-prueth is built-in
while HSR is configured as a module.
