a6adef8987 ARM: SoC fixes for v6.7
Most of the changes are devicetree fixes for NXP, Mediatek, Rockchips
 Arm machines as well as Microchip RISC-V, and most of these address
 build-time warnings for spec violations and other minor issues. One of
 the Mediatek warnings was enabled by default and prevented a clean build.
 The ones that address serious runtime issues are all on the i.MX platform:
 
  - a boot time panic on imx8qm
  - USB hanging under load on imx8
  - regressions on the imx93 ethernet phy
 
 Code fixes include a minor error handling for the i.MX PMU driver, and
 a number of firmware driver fixes:
 
  - OP-TEE fix for supplicant based device enumeration, and a new
    sysfs attribute to needed to fix a race against userspace
 
  - Arm SCMI fix for possible truncation/overflow in the frequency
    computations
 
  - Multiple FF-A fixes for the newly added notification support.

8f2244c9af leds: class: Don't expose color sysfs entry
The commit c7d80059b0 ("leds: class: Store the color index in struct
led_classdev") introduced a new sysfs entry "color" that is commonly
created for the led classdev.  Unfortunately, this conflicts with the
"color" sysfs entry of already existing drivers such as Logitech HID
or System76 ACPI drivers.  The driver probe fails due to the conflict,
hence it leads to a severe regression with the missing keyboard, for
example.

This patch reverts partially the change in the commit above for
removing the led class color sysfs entries again for addressing the
regressions.  The newly introduced led_classdev.color field is kept as
it's already used by other driver.

Fixes: c7d80059b0 ("leds: class: Store the color index in struct led_classdev")

Pull CXL (Compute Express Link) updates from Dan Williams:
 "The main new functionality this time is work to allow Linux to
  natively handle CXL link protocol errors signalled via PCIe AER for
  current generation CXL platforms. This required some enlightenment of
  the PCIe AER core to workaround the fact that current generation RCH
  (Restricted CXL Host) platforms physically hide topology details and
  registers via a mechanism called RCRB (Root Complex Register Block).

  The next major highlight is reworks to address bugs in parsing region
  configurations for next generation VH (Virtual Host) topologies. The
  old broken algorithm is replaced with a simpler one that significantly
  increases the number of region configurations supported by Linux. This
  is again relevant for error handling so that forward and reverse
  address translation of memory errors can be carried out by Linux for
  memory regions instantiated by platform firmware.

  As for other cross-tree work, the ACPI table parsing code has been
  refactored for reuse parsing the "CDAT" structure which is an
  ACPI-like data structure that is reported by CXL devices. That work is
  in preparation for v6.8 support for CXL QoS. Think of this as dynamic
  generation of NUMA node topology information generated by Linux rather
  than platform firmware.

  Lastly, a number of internal object lifetime issues have been resolved
  along with misc. fixes and feature updates (decoders_committed sysfs
  ABI).

  Summary:

   - Add support for RCH (Restricted CXL Host) Error recovery

   - Fix several region assembly bugs

   - Fix mem-device lifetime issues relative to the sanitize command and
     RCH topology.

Pull unified attestation reporting from Dan Williams:
 "In an ideal world there would be a cross-vendor standard attestation
  report format for confidential guests along with a common device
  definition to act as the transport.

  In the real world the situation ended up with multiple platform
  vendors inventing their own attestation report formats with the
  SEV-SNP implementation being a first mover to define a custom
  sev-guest character device and corresponding ioctl(). Later, this
  configfs-tsm proposal intercepted an attempt to add a tdx-guest
  character device and a corresponding new ioctl(). It also anticipated
  ARM and RISC-V showing up with more chardevs and more ioctls().

  The proposal takes for granted that Linux tolerates the vendor report
  format differentiation until a standard arrives. From talking with
  folks involved, it sounds like that standardization work is unlikely
  to resolve anytime soon. It also takes the position that kernfs ABIs
  are easier to maintain than ioctl(). The result is a shared configfs
  mechanism to return per-vendor report-blobs with the option to later
  support a standard when that arrives.

  Part of the goal here also is to get the community into the
  "uncomfortable, but beneficial to the long term maintainability of the
  kernel" state of talking to each other about their differentiation and
  opportunities to collaborate. Think of this like the device-driver
  equivalent of the common memory-management infrastructure for
  confidential-computing being built up in KVM.

  As for establishing an "upstream path for cross-vendor
  confidential-computing device driver infrastructure" this is something
  I want to discuss at Plumbers. At present, the multiple vendor
  proposals for assigning devices to confidential computing VMs likely
  needs a new dedicated repository and maintainer team, but that is a
  discussion for v6.8.

  For now, Greg and Thomas have acked this approach and this is passing
  is AMD, Intel, and Google tests.

  Summary:

   - Introduce configfs-tsm as a shared ABI for confidential computing
     attestation reports

   - Convert sev-guest to additionally support configfs-tsm alongside
     its vendor specific ioctl()

   - Added signed attestation report retrieval to the tdx-guest driver
     forgoing a new vendor specific ioctl()

2c40c1c6ad USB/Thunderbolt changes for 6.7-rc1
Here is the "big" set of USB and Thunderbolt changes for 6.7-rc1.
 Nothing really major in here, just lots of constant development for new
 hardware.  Included in here are:
   - Thunderbolt (i.e. USB4) fixes for reported issues and support for
     new hardware types and devices
   - USB typec additions of new drivers and cleanups for some existing
     ones
   - xhci cleanups and expanded tracing support and some platform
     specific updates
   - USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio, spi,
     and i2c drivers for that type of device (all acked by the respective
     subsystem maintainers.)
   - lots of USB gadget driver updates and cleanups
   - new USB dwc3 platforms supported, as well as other dwc3 fixes and
     cleanups
   - USB chipidea driver updates
   - other smaller driver cleanups and additions, full details in the
     shortlog
 
 All of these have been in the linux-next tree for a while with no
 reported problems, EXCEPT for some merge conflicts that you will run
 into in your tree.  2 of them are in device-tree files, which will be
 trivial to resolve (accept both sides), and the last in the
 drivers/gpio/gpio-ljca.c file, in the remove callback, resolution should
 be pretty trivial (take the version in this branch), see here:
 	https://lore.kernel.org/all/20231016134159.11d8f849@canb.auug.org.au/
 for details, or I can provide a resolved merge point if needed.

7269cba53d tee: optee: Fix supplicant based device enumeration
Currently supplicant dependent optee device enumeration only registers
devices whenever tee-supplicant is invoked for the first time. But it
forgets to remove devices when tee-supplicant daemon stops running and
closes its context gracefully. This leads to following error for fTPM
driver during reboot/shutdown:

[   73.466791] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024

Fix this by adding an attribute for supplicant dependent devices so that
the user-space service can detect and detach supplicant devices before
closing the supplicant:

$ for dev in /sys/bus/tee/devices/*; do if [[ -f "$dev/need_supplicant" && -f "$dev/driver/unbind" ]]; \
      then echo $(basename "$dev") > $dev/driver/unbind; fi done

ecae0bd517 Many singleton patches against the MM code. The patch series which are
included in this merge do the following:
 
 - Kemeng Shi has contributed some compation maintenance work in the
   series "Fixes and cleanups to compaction".
 
 - Joel Fernandes has a patchset ("Optimize mremap during mutual
   alignment within PMD") which fixes an obscure issue with mremap()'s
   pagetable handling during a subsequent exec(), based upon an
   implementation which Linus suggested.
 
 - More DAMON/DAMOS maintenance and feature work from SeongJae Park i the
   following patch series:
 
 	mm/damon: misc fixups for documents, comments and its tracepoint
 	mm/damon: add a tracepoint for damos apply target regions
 	mm/damon: provide pseudo-moving sum based access rate
 	mm/damon: implement DAMOS apply intervals
 	mm/damon/core-test: Fix memory leaks in core-test
 	mm/damon/sysfs-schemes: Do DAMOS tried regions update for only one apply interval
 
 - In the series "Do not try to access unaccepted memory" Adrian Hunter
   provides some fixups for the recently-added "unaccepted memory' feature.
   To increase the feature's checking coverage.  "Plug a few gaps where
   RAM is exposed without checking if it is unaccepted memory".
 
 - In the series "cleanups for lockless slab shrink" Qi Zheng has done
   some maintenance work which is preparation for the lockless slab
   shrinking code.
 
 - Qi Zheng has redone the earlier (and reverted) attempt to make slab
   shrinking lockless in the series "use refcount+RCU method to implement
   lockless slab shrink".
 
 - David Hildenbrand contributes some maintenance work for the rmap code
   in the series "Anon rmap cleanups".
 
 - Kefeng Wang does more folio conversions and some maintenance work in
   the migration code.  Series "mm: migrate: more folio conversion and
   unification".
 
 - Matthew Wilcox has fixed an issue in the buffer_head code which was
   causing long stalls under some heavy memory/IO loads.  Some cleanups
   were added on the way.  Series "Add and use bdev_getblk()".
 
 - In the series "Use nth_page() in place of direct struct page
   manipulation" Zi Yan has fixed a potential issue with the direct
   manipulation of hugetlb page frames.
 
 - In the series "mm: hugetlb: Skip initialization of gigantic tail
   struct pages if freed by HVO" has improved our handling of gigantic
   pages in the hugetlb vmmemmep optimizaton code.  This provides
   significant boot time improvements when significant amounts of gigantic
   pages are in use.
 
 - Matthew Wilcox has sent the series "Small hugetlb cleanups" - code
   rationalization and folio conversions in the hugetlb code.
 
 - Yin Fengwei has improved mlock()'s handling of large folios in the
   series "support large folio for mlock"
 
 - In the series "Expose swapcache stat for memcg v1" Liu Shixin has
   added statistics for memcg v1 users which are available (and useful)
   under memcg v2.
 
 - Florent Revest has enhanced the MDWE (Memory-Deny-Write-Executable)
   prctl so that userspace may direct the kernel to not automatically
   propagate the denial to child processes.  The series is named "MDWE
   without inheritance".
 
 - Kefeng Wang has provided the series "mm: convert numa balancing
   functions to use a folio" which does what it says.
 
 - In the series "mm/ksm: add fork-exec support for prctl" Stefan Roesch
   makes is possible for a process to propagate KSM treatment across
   exec().
 
 - Huang Ying has enhanced memory tiering's calculation of memory
   distances.  This is used to permit the dax/kmem driver to use "high
   bandwidth memory" in addition to Optane Data Center Persistent Memory
   Modules (DCPMM).  The series is named "memory tiering: calculate
   abstract distance based on ACPI HMAT"
 
 - In the series "Smart scanning mode for KSM" Stefan Roesch has
   optimized KSM by teaching it to retain and use some historical
   information from previous scans.
 
 - Yosry Ahmed has fixed some inconsistencies in memcg statistics in the
   series "mm: memcg: fix tracking of pending stats updates values".
 
 - In the series "Implement IOCTL to get and optionally clear info about
   PTEs" Peter Xu has added an ioctl to /proc/<pid>/pagemap which permits
   us to atomically read-then-clear page softdirty state.  This is mainly
   used by CRIU.
 
 - Hugh Dickins contributed the series "shmem,tmpfs: general maintenance"
   - a bunch of relatively minor maintenance tweaks to this code.
 
 - Matthew Wilcox has increased the use of the VMA lock over file-backed
   page faults in the series "Handle more faults under the VMA lock".  Some
   rationalizations of the fault path became possible as a result.

   Stoakes has simplified and improved the GUP interface with an eye to
   providing groundwork for future improvements.
 
 - Andrey Konovalov has sent along the series "kasan: assorted fixes and
   improvements" which does those things.
 
 - Some page allocator maintenance work from Kemeng Shi in the series
   "Two minor cleanups to break_down_buddy_pages".
 
 - In thes series "New selftest for mm" Breno Leitao has developed
   another MM self test which tickles a race we had between madvise() and
   page faults.
 
 - In the series "Add folio_end_read" Matthew Wilcox provides cleanups
   and an optimization to the core pagecache code.
 
 - Nhat Pham has added memcg accounting for hugetlb memory in the series
   "hugetlb memcg accounting".
 
 - Cleanups and rationalizations to the pagemap code from Lorenzo
   Stoakes, in the series "Abstract vma_merge() and split_vma()".
 
 - Audra Mitchell has fixed issues in the procfs page_owner code's new
   timestamping feature which was causing some misbehaviours.  In the
   series "Fix page_owner's use of free timestamps".
 
 - Lorenzo Stoakes has fixed the handling of new mappings of sealed files
   in the series "permit write-sealed memfd read-only shared mappings".
 
 - Mike Kravetz has optimized the hugetlb vmemmap optimization in the
   series "Batch hugetlb vmemmap modification operations".
 
 - Some buffer_head folio conversions and cleanups from Matthew Wilcox in
   the series "Finish the create_empty_buffers() transition".
 
 - As a page allocator performance optimization Huang Ying has added
   automatic tuning to the allocator's per-cpu-pages feature, in the series
   "mm: PCP high auto-tuning".
 
 - Roman Gushchin has contributed the patchset "mm: improve performance
   of accounted kernel memory allocations" which improves their performance
   by ~30% as measured by a micro-benchmark.
 
 - folio conversions from Kefeng Wang in the series "mm: convert page
   cpupid functions to folios".
 
 - Some kmemleak fixups in Liu Shixin's series "Some bugfix about
   kmemleak".

   off the allocation fallback list.  This is done in the series "handle
   memoryless nodes more appropriately".
 
 - khugepaged conversions from Vishal Moola in the series "Some
   khugepaged folio conversions".

   - Matthew Wilcox has fixed an issue in the buffer_head code which was
     causing long stalls under some heavy memory/IO loads. Some cleanups
     were added on the way. Series 'Add and use bdev_getblk()'

   - In the series 'Use nth_page() in place of direct struct page
     manipulation' Zi Yan has fixed a potential issue with the direct
     manipulation of hugetlb page frames

   - In the series 'mm: hugetlb: Skip initialization of gigantic tail
     struct pages if freed by HVO' has improved our handling of gigantic
     pages in the hugetlb vmmemmep optimizaton code. This provides
     significant boot time improvements when significant amounts of
     gigantic pages are in use

   - Matthew Wilcox has sent the series 'Small hugetlb cleanups' - code
     rationalization and folio conversions in the hugetlb code

   - Yin Fengwei has improved mlock()'s handling of large folios in the
     series 'support large folio for mlock'

   - In the series 'Expose swapcache stat for memcg v1' Liu Shixin has
     added statistics for memcg v1 users which are available (and
     useful) under memcg v2

   - Florent Revest has enhanced the MDWE (Memory-Deny-Write-Executable)
     prctl so that userspace may direct the kernel to not automatically
     propagate the denial to child processes. The series is named 'MDWE
     without inheritance'

   - Kefeng Wang has provided the series 'mm: convert numa balancing
     functions to use a folio' which does what it says

   - In the series 'mm/ksm: add fork-exec support for prctl' Stefan
     Roesch makes is possible for a process to propagate KSM treatment
     across exec()

   - Huang Ying has enhanced memory tiering's calculation of memory
     distances. This is used to permit the dax/kmem driver to use 'high
     bandwidth memory' in addition to Optane Data Center Persistent
     Memory Modules (DCPMM). The series is named 'memory tiering:
     calculate abstract distance based on ACPI HMAT'

   - In the series 'Smart scanning mode for KSM' Stefan Roesch has
     optimized KSM by teaching it to retain and use some historical
     information from previous scans

   - Yosry Ahmed has fixed some inconsistencies in memcg statistics in
     the series 'mm: memcg: fix tracking of pending stats updates
     values'

   - In the series 'Implement IOCTL to get and optionally clear info
     about PTEs' Peter Xu has added an ioctl to /proc/<pid>/pagemap
     which permits us to atomically read-then-clear page softdirty
     state. This is mainly used by CRIU

   - Hugh Dickins contributed the series 'shmem,tmpfs: general
     maintenance', a bunch of relatively minor maintenance tweaks to
     this code

   - Matthew Wilcox has increased the use of the VMA lock over
     file-backed page faults in the series 'Handle more faults under the
     VMA lock'. Some rationalizations of the fault path became possible
     as a result

   - In the series 'mm/rmap: convert page_move_anon_rmap() to
     folio_move_anon_rmap()' David Hildenbrand has implemented some
     cleanups and folio conversions

   - In the series 'various improvements to the GUP interface' Lorenzo
     Stoakes has simplified and improved the GUP interface with an eye
     to providing groundwork for future improvements

   - Andrey Konovalov has sent along the series 'kasan: assorted fixes
     and improvements' which does those things

   - Some page allocator maintenance work from Kemeng Shi in the series
     'Two minor cleanups to break_down_buddy_pages'

   - In thes series 'New selftest for mm' Breno Leitao has developed
     another MM self test which tickles a race we had between madvise()
     and page faults

   - In the series 'Add folio_end_read' Matthew Wilcox provides cleanups
     and an optimization to the core pagecache code

   - Nhat Pham has added memcg accounting for hugetlb memory in the
     series 'hugetlb memcg accounting'

   - Cleanups and rationalizations to the pagemap code from Lorenzo
     Stoakes, in the series 'Abstract vma_merge() and split_vma()'

   - Audra Mitchell has fixed issues in the procfs page_owner code's new
     timestamping feature which was causing some misbehaviours. In the
     series 'Fix page_owner's use of free timestamps'

   - Lorenzo Stoakes has fixed the handling of new mappings of sealed
     files in the series 'permit write-sealed memfd read-only shared
     mappings'

   - Mike Kravetz has optimized the hugetlb vmemmap optimization in the
     series 'Batch hugetlb vmemmap modification operations'

   - Some buffer_head folio conversions and cleanups from Matthew Wilcox
     in the series 'Finish the create_empty_buffers() transition'

   - As a page allocator performance optimization Huang Ying has added
     automatic tuning to the allocator's per-cpu-pages feature, in the
     series 'mm: PCP high auto-tuning'

   - Roman Gushchin has contributed the patchset 'mm: improve
     performance of accounted kernel memory allocations' which improves
     their performance by ~30% as measured by a micro-benchmark

   - folio conversions from Kefeng Wang in the series 'mm: convert page
     cpupid functions to folios'

   - Some kmemleak fixups in Liu Shixin's series 'Some bugfix about
     kmemleak'

   - Qi Zheng has improved our handling of memoryless nodes by keeping
     them off the allocation fallback list. This is done in the series
     'handle memoryless nodes more appropriately'

   - khugepaged conversions from Vishal Moola in the series 'Some
     khugepaged folio conversions'"

[ bcachefs conflicts with the dynamically allocated shrinkers have been
  resolved as per Stephen Rothwell in

     https://lore.kernel.org/all/20230913093553.4290421e@canb.auug.org.au/

1e0c505e13 asm-generic updates for v6.7
The ia64 architecture gets its well-earned retirement as planned,
 now that there is one last (mostly) working release that will
 be maintained as an LTS kernel.
 
 The architecture specific system call tables are updated for
 the added map_shadow_stack() syscall and to remove references
 to the long-gone sys_lookup_dcookie() syscall.

db74e16258 crypto: qat - add rate limiting sysfs interface
Add an interface for the rate limiting feature which allows to add,
remove and modify a QAT SLA (Service Level Agreement).

This adds a new sysfs attribute group, `qat_rl`, which can be accessed
from /sys/bus/pci/devices/<BUS:DEV:FUNCTION> with the following
hierarchy:
    |-+ qat_rl
      |---- id  (RW) # SLA identifier
      |---- cir (RW) # Committed Information Rate
      |---- pir (RW) # Peak Information Rate
      |---- srv (RW) # Service to be rate limited
      |---- rp  (RW) (HEX) # Ring pairs to be rate limited
      |---- cap_rem  (RW)  # Remaining capability for a service
      |---- sla_op   (WO)  # Allows to perform an operation on an SLA

The API works by setting the appropriate RW attributes and then
issuing a command through the `sla_op`. For example, to create an SLA, a
user needs to input the necessary data into the attributes cir, pir, srv
and rp and then write into `sla_op` the command `add` to execute the
operation.
The API also provides `cap_rem` attribute to get information about
the remaining device capability within a certain service which is
required when setting an SLA.

b4b6cc10c6 IIO: 1st set of new device support, features and cleanup for 6.7
Particularly great to see a resolver driver move out of staging via a
 massive set of changes.  Only took 13 years :)
 
 One small patch added then reverted due to a report of test breakage
 (ashai-kasei,ak8975: Drop deprecated enums.)
 
 An immutable branch was used for some hid-senors changes in case
 there was a need to take them into the HID tree as well.
 
 New device support
 -----------------
 
 adi,hmc425a
   - Add support for HMC540SLP3E broadband 4-bit digital attenuator.
 kionix,kx022a
   - Add support for the kx132-1211 accelerometer. Require significant
     driver rework to enable this including add a chip type specific
     structure to deal with the chip differences.
   - Add support for the kx132acr-lbz accelerometer (subset of the kx022a
     feature set).
 lltc,ltc2309
   - New driver for this 8 channel ADC.
 microchip,mcp3911
   - Add support for rest of mcp391x family of ADCs (there are various
     differences beyond simple channel count variation.
     Series includes some general driver cleanup.
 microchip,mcp3564
   - New driver for MCP3461, MCP3462, MCP3464, MCP3541, MCP3562, MCP3564
     and their R variants of 16/24bit ADCs. A few minor fixed followed.
 rohm,bu1390
   - New driver for this pressure sensor.
 
 Staging graduation
 ------------------
 
 adi,ad1210 (after 13 or so years :)
   - More or less a complete (step-wise) rewrite of this resolver driver
     to bring it up to date with modern IIO standards.  The fault signal
     handling mapping to event channels was particularly complex and
     significant part of the changes.
 
 Features
 --------
 
 iio-core
  - Add chromacity and color temperature channel types.
 adi,ad7192
   - Oversampling ratio control (called fast settling in datasheet).
 adi,adis16475
   - Add core support and then driver support for delta angle and delta
     velocity channels. These are intended for summation to establish
     angle and velocity changes over larger timescales.  Fix was
     needed for alignment after the temperature channel.  Further fix
     reduced set of devices for which the buffer support was applicable
     as seems burst reads don't cover these on all devices.
 hid-sensors-als
   - Chromacity and color temperatures support including in amd sfh.
 stx104
   - Add support for counter subsystem to this multipurpose device.
 ti,twl6030
   - Add missing device tree binding description.
 
 Clean up and minor fixes.
 ------------------------
 
 treewide
   - Drop some unused declarations across IIO.
   - Make more use of device_get_match_data() instead of OF specific
     approaches.
 Similar cleanup to sets of drivers.
   - Stop platform remove callbacks returning anything by using the
     temporary remove_new() callback.
   - Use i2c_get_match_data() to cope nicely with all types of ID table
     entry.
   - Use device_get_match_data() for various platform device to cope
     with more types of firmware.
   - Convert from enum to pointer in ID tables allowing use of
     i2c_get_match_data().
   - Fix sorting on some ID tables.
   - Include specific string helper headers rather than simply string_helpers.h
 docs
   - Better description of the ordering requirements etc for
     available_scan_masks.
 tools
   - Handle alignment of mixed sizes where the last element isn't the biggest
     correctly. Seems that doesn't happen often!
 adi,ad2s1210
   - Lots of work from David Lechner on this driver including a few fixes
     that are going with the rework to avoid slowing that down.
 adi,ad4310
   - Replace deprecated devm_clk_register()

   - Bring the channel function setting inline with the datasheet.
 adi,ad7192
   - Change to FIELD_PREP(), FIELD_GET().
   - Calculate f_order from the sinc filter and chop filter states.
   - Move more per chip config into data in struct ad7192_chip_info
   - Cleanup unused parameter in channel macros.
 adi,adf4350
   - Make use of devm_* to simplify error handling for many of the setup
     calls in probe() / tear down in remove() and error paths.  Some more
     work to be done on this one.
   - Use dev_err_probe() for errors in probe() callback.
 adi,adf4413
   - Typo in function name prefix.
 adi,adxl345
   - Add channel scale to the chip type specific structure and drop
     using a type field previously used for indirection.
 asahi,ak8985
   - Fix a mismatch introduced when switching from enum->pointers
     in the match tables.
 amlogic,meson
   - Expand error logging during probe.
 invensense,mpu6050
   - Support level-shifter control. Whilst no one is sure exactly what this
     is doing it is needed for some old boards.
   - Document mount-matrix dt-binding.
 mediatek,mt6577
   - Use devm_clk_get_enabled() to replace open coded version and move
     everything over to being device managed. Drop now empty remove()
     callback. Fix follows to put the drvdata back.
   - Use dev_err_probe() for error reporting in probe() callback.
 memsic,mxc4005
   - Add of_match_table.
 microchip,mcp4725
   - Move various chip specific data from being looked up by chip ID to
     data in the chip type specific structure.
 silicon-labs,si7005
   - Add of_match_table and entry in trivial-devices.yaml
 st,lsm6dsx
   - Add missing mount-matrix dt binding documentation.

   - Use devm_clk_get_enabled() and some other devm calls to move everything
     over to being device managed.  Drop now empty remove() callback.
   - Use dev_err_probe() to better handled deferred probing and tidy up
     error reporting in probe() callback.

environment) to take a measurement of its launch state, sign it and
submit it to a verifying party. Upon successful attestation that
verifies the integrity of the TVM additional secrets may be deployed.
The concept is common across TSMs, but the implementations are
unfortunately vendor specific. While the industry grapples with a common
definition of this attestation format [1], Linux need not make this
problem worse by defining a new ABI per TSM that wants to perform a
similar operation. The current momentum has been to invent new ioctl-ABI
per TSM per function which at best is an abdication of the kernel's
responsibility to make common infrastructure concepts share common ABI.

The proposal, targeted to conceptually work with TDX, SEV-SNP, COVE if
not more, is to define a configfs interface to retrieve the TSM-specific
blob.

    report=/sys/kernel/config/tsm/report/report0
    mkdir $report
    dd if=binary_userdata_plus_nonce > $report/inblob
    hexdump $report/outblob

This approach later allows for the standardization of the attestation
blob format without needing to invent a new ABI. Once standardization
happens the standard format can be emitted by $report/outblob and
indicated by $report/provider, or a new attribute like
"$report/tcg_coco_report" can emit the standard format alongside the
vendor format.

Review of previous iterations of this interface identified that there is
a need to scale report generation for multiple container environments
[2]. Configfs enables a model where each container can bind mount one or
more report generation item instances. Still, within a container only a
single thread can be manipulating a given configuration instance at a
time. A 'generation' count is provided to detect conflicts between
multiple threads racing to configure a report instance.

The SEV-SNP concepts of "extended reports" and "privilege levels" are
optionally enabled by selecting 'tsm_report_ext_type' at register_tsm()
time. The expectation is that those concepts are generic enough that
they may be adopted by other TSM implementations. In other words,
configfs-tsm aims to address a superset of TSM specific functionality
with a common ABI where attributes may appear, or not appear, based on
the set of concepts the implementation supports.

59de2a56d1 usb: typec: Link enumerated USB devices with Type-C partner
Adding functions that USB hub code can use to inform the
Type-C class about connected USB devices.

Once taken into use, it will allow the Type-C port drivers
to power off components that are not needed, for example if
USB2 device is enumerated, everything that is only relevant
for USB3 (retimers, etc.), can be powered off.

This will also create a symlink "typec" for the USB devices
pointing to the USB Type-C partner device.

d807f0240c crypto: qat - add cnv_errors debugfs file
The Compress and Verify (CnV) feature check and ensures data integrity
in the compression operation. The implementation of CnV keeps a record
of the CnV errors that have occurred since the driver was loaded.

Expose CnV error stats by providing the "cnv_errors" file under
debugfs. This includes the number of errors detected up to now and
the type of the last error. The error count is provided on a per
Acceleration Engine basis and it is reset every time the driver is loaded.

e079231676 crypto: qat - add pm_status debugfs file
QAT devices implement a mechanism that allows them to go autonomously
to a low power state depending on the load.

Expose power management info by providing the "pm_status" file under
debugfs. This includes PM state, PM event log, PM event counters, PM HW
CSRs, per-resource type constrain counters and per-domain power gating
status specific to the QAT device.

This information is retrieved from (1) the FW by means of
ICP_QAT_FW_PM_INFO command, (2) CSRs and (3) counters collected by the
device driver.

In addition, add logic to keep track and report power management event
interrupts and acks/nacks sent to FW to allow/prevent state transitions.

type codes.

These fields affect the type of audio device that Windows detects, so
being able to modify this is useful when it would be advantageous for
a gadget to be detected as something other than a generic
speaker/microphone.

The fields default to microphone for the capture type field and speaker
for the playback type field as was the case before.
