Pull drm updates from Dave Airlie:
 "The usual lots of work all over the place.

  i915 has gotten some Alderlake work and prelim DG1 code, along with a
  major locking rework over the GEM code, and brings back the property
  of timing out long running jobs using a watchdog. amdgpu has some
  Alderbran support (new GPU), freesync HDMI support along with a lot
  other fixes.

1e9599dfc4 linux-kselftest-kunit-5.13-rc1 
This KUnit update for Linux 5.13-rc1 consists of several fixes and
 new feature to support failure from dynamic analysis tools such as
 UBSAN and fake ops for testing.
 
 - a fake ops struct for testing a "free" function to complain if it
   was called with an invalid argument, or caught a double-free. Most
   return void and have no normal means of signalling failure
   (e.g. super_operations, iommu_ops, etc.).

  This implements generic support for resources which can be controlled

  there's X number of these on the system and this cgroup subtree can
  have upto Y of those.

  The first user is the address space IDs used for virtual machine

Pull printk updates from Petr Mladek:

 - Stop synchronizing kernel log buffer readers by logbuf_lock. As a
   result, the access to the buffer is fully lockless now.

   Note that printk() itself still uses locks because it tries to flush
   the messages to the console immediately. Also the per-CPU temporary
   buffers are still there because they prevent infinite recursion and
   serialize backtraces from NMI. All this is going to change in the
   future.

 - kmsg_dump API rework and cleanup as a side effect of the logbuf_lock
   removal.

 - Make bstr_printf() aware that %pf and %pF formats could deference the
   given pointer.

 - Show also page flags by %pGp format.

 - Clarify the documentation for plain pointer printing.

 - Do not show no_hash_pointers warning multiple times.

 - Update Senozhatsky email address.

916a75965e kgdb patches for 5.13 
Exclusively tidy ups this cycle. Most of them are thanks to Sumit Garg
 and, as it happens, the clean ups do result in a slight increase in
 the line count. This is due to registering kdb commands using data
 structures rather than function calls which, in turn, simplifies the
 memory management during command registration.
 
 In addition to changes to command registration we also have some dead
 code removal, a clearer implementation of environment variable handling
 and a typo fix.

 - a rather large change to the vfio-ap code to fix circular locking
   dependencies when updating crypto masks.
 
 - move QAOB handling from qdio layer down to drivers.

 - add protected virtualization guest and host indication files, which

e7c6e405e1 Fix misc new gcc warnings 
It seems like Fedora 34 ends up enabling a few new gcc warnings, notably
"-Wstringop-overread" and "-Warray-parameter".

Both of them cause what seem to be valid warnings in the kernel, where
we have array size mismatches in function arguments (that are no longer
just silently converted to a pointer to element, but actually checked).

This fixes most of the trivial ones, by making the function declaration
match the function definition, and in the case of intel_pm.c, removing
the over-specified array size from the argument declaration.

At least one 'stringop-overread' warning remains in the i915 driver, but
that one doesn't have the same obvious trivial fix, and may or may not
actually be indicative of a bug.

[ It was a mistake to upgrade one of my machines to Fedora 34 while
  being busy with the merge window, but if this is the extent of the
  compiler upgrade problems, things are better than usual    - Linus ]

   credentials; including support for the SELinux and Smack. My clumsy
   attempt at a proper fix for AppArmor didn't quite pass muster so John
   is working on a proper AppArmor patch, in the meantime this set of
   patches shouldn't change the behavior of AppArmor in any way. This
   change explains the bulk of the diffstat beyond security/.

 - Fix a problem where we were not properly terminating the permission
   list for two SELinux object classes.

Pull AFS updates from David Howells:
 "Use the new netfs lib.

  Begin the process of overhauling the use of the fscache API by AFS and
  the introduction of support for features such as Transparent Huge
  Pages (THPs).

   - Add some support for THPs, including using core VM helper functions
     to find details of pages.

   - Use the ITER_XARRAY I/O iterator to mediate access to the pagecache
     as this handles THPs and doesn't require allocation of large bvec
     arrays.

   - Delegate address_space read/pre-write I/O methods for AFS to the
     netfs helper library. A method is provided to the library that
     allows it to issue a read against the server.

     This includes a change in use for PG_fscache (it now indicates a
     DIO write in progress from the marked page), so a number of waits
     need to be deployed for it.

   - Split the core AFS writeback function to make it easier to modify
     in future patches to handle writing to the cache. [This might
     feasibly make more sense moved out into my fscache-iter branch].

  I've tested these with "xfstests -g quick" against an AFS volume
  (xfstests needs patching to make it work). With this, AFS without a
  cache passes all expected xfstests; with a cache, there's an extra
  failure, but that's also there before these patches. Fixing that
  probably requires a greater overhaul (as can be found on my
  fscache-iter branch, but that's for a later time).

  Thanks should go to Marc Dionne and Jeff Altman of AuriStor for
  exercising the patches in their test farm also"

Merge tag 'netfs-lib-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull network filesystem helper library updates from David Howells:
 "Here's a set of patches for 5.13 to begin the process of overhauling
  the local caching API for network filesystems. This set consists of
  two parts:

  (1) Add a helper library to handle the new VM readahead interface.

      This is intended to be used unconditionally by the filesystem
      (whether or not caching is enabled) and provides a common
      framework for doing caching, transparent huge pages and, in the
      future, possibly fscrypt and read bandwidth maximisation. It also
      allows the netfs and the cache to align, expand and slice up a
      read request from the VM in various ways; the netfs need only
      provide a function to read a stretch of data to the pagecache and
      the helper takes care of the rest.

  (2) Add an alternative fscache/cachfiles I/O API that uses the kiocb
      facility to do async DIO to transfer data to/from the netfs's
      pages, rather than using readpage with wait queue snooping on one
      side and vfs_write() on the other. It also uses less memory, since
      it doesn't do buffered I/O on the backing file.

      Note that this uses SEEK_HOLE/SEEK_DATA to locate the data
      available to be read from the cache. Whilst this is an improvement
      from the bmap interface, it still has a problem with regard to a
      modern extent-based filesystem inserting or removing bridging
      blocks of zeros. Fixing that requires a much greater overhaul.

  This is a step towards overhauling the fscache API. The change is
  opt-in on the part of the network filesystem. A netfs should not try
  to mix the old and the new API because of conflicting ways of handling
  pages and the PG_fscache page flag and because it would be mixing DIO
  with buffered I/O. Further, the helper library can't be used with the
  old API.

  This does not change any of the fscache cookie handling APIs or the
  way invalidation is done at this time.

  In the near term, I intend to deprecate and remove the old I/O API
  (fscache_allocate_page{,s}(), fscache_read_or_alloc_page{,s}(),
  fscache_write_page() and fscache_uncache_page()) and eventually
  replace most of fscache/cachefiles with something simpler and easier
  to follow.

  This patchset contains the following parts:

   - Some helper patches, including provision of an ITER_XARRAY iov
     iterator and a function to do readahead expansion.

   - Patches to add the netfs helper library.

   - A patch to add the fscache/cachefiles kiocb API.

   - A pair of patches to fix some review issues in the ITER_XARRAY and
     read helpers as spotted by Al and Willy.

  Jeff Layton has patches to add support in Ceph for this that he
  intends for this merge window. I have a set of patches to support AFS
  that I will post a separate pull request for.

  With this, AFS without a cache passes all expected xfstests; with a
  cache, there's an extra failure, but that's also there before these
  patches. Fixing that probably requires a greater overhaul. Ceph also
  passes the expected tests.

  I also have patches in a separate branch to tidy up the handling of
  PG_fscache/PG_private_2 and their contribution to page refcounting in
  the core kernel here, but I haven't included them in this set and will
  route them separately"

 "This builds on last cycle's LTO work, and allows the arm64 kernels to
  be built with Clang's Control Flow Integrity feature. This feature has
  happily lived in Android kernels for almost 3 years[1], so I'm excited
  to have it ready for upstream.

  The wide diffstat is mainly due to the treewide fixing of mismatched
  list_sort prototypes. Other things in core kernel are to address
  various CFI corner cases. The largest code portion is the CFI runtime
  implementation itself (which will be shared by all architectures
  implementing support for CFI). The arm64 pieces are Acked by arm64
  maintainers rather than coming through the arm64 tree since carrying
  this tree over there was going to be awkward.

  CFI support for x86 is still under development, but is pretty close.
  There are a handful of corner cases on x86 that need some improvements
  to Clang and objtool, but otherwise works well.

ea6b2098dd cfg80211: fix locking in netlink owner interface destruction 
Harald Arnesen reported [1] a deadlock at reboot time, and after
he captured a stack trace a picture developed of what's going on:

The distribution he's using is using iwd (not wpa_supplicant) to
manage wireless. iwd will usually use the "socket owner" option
when it creates new interfaces, so that they're automatically
destroyed when it quits (unexpectedly or otherwise). This is also
done by wpa_supplicant, but it doesn't do it for the normal one,
only for additional ones, which is different with iwd.

Anyway, during shutdown, iwd quits while the netdev is still UP,
i.e. IFF_UP is set. This causes the stack trace that Linus so
nicely transcribed from the pictures:

cfg80211_destroy_iface_wk() takes wiphy_lock
 -> cfg80211_destroy_ifaces()
  ->ieee80211_del_iface
    ->ieeee80211_if_remove
      ->cfg80211_unregister_wdev
        ->unregister_netdevice_queue
          ->dev_close_many
            ->__dev_close_many
              ->raw_notifier_call_chain
                ->cfg80211_netdev_notifier_call
and that last call tries to take wiphy_lock again.

In commit a05829a722 ("cfg80211: avoid holding the RTNL when
calling the driver") I had taken into account the possibility of
recursing from cfg80211 into cfg80211_netdev_notifier_call() via
the network stack, but only for NETDEV_UNREGISTER, not for what
happens here, NETDEV_GOING_DOWN and NETDEV_DOWN notifications.

Additionally, while this worked still back in commit 78f22b6a3a
("cfg80211: allow userspace to take ownership of interfaces"), it
missed another corner case: unregistering a netdev will cause
dev_close() to be called, and thus stop wireless operations (e.g.
disconnecting), but there are some types of virtual interfaces in
wifi that don't have a netdev - for that we need an additional
call to cfg80211_leave().

So, to fix this mess, change cfg80211_destroy_ifaces() to not
require the wiphy_lock(), but instead make it acquire it, but
only after it has actually closed all the netdevs on the list,
and then call cfg80211_leave() as well before removing them
from the driver, to fix the second issue. The locking change in
this requires modifying the nl80211 call to not get the wiphy
lock passed in, but acquire it by itself after flushing any
potentially pending destruction requests.

4a0225c3d2 spi: Updates for v5.13 
The only core work for SPI this time around is the completion of the
 conversion to the new style method for specifying transfer delays,
 meaning we can cope with what most controllers support more directly
 using conversions in the core rather than open coding in drivers.
 Otherwise it's a good stack of cleanups and fixes plus a few new
 drivers.
 
 The conversion to new style transfer delay will cause an issue with a
 newly added staging driver which has a straightforward resolution in
 -next.
 
  - Completion of the conversion to new style transfer delay
    configuration.
  - Introduction and use of module_parport_driver() helper, merged here
    as there's no parport tree.
  - Support for Altera SoCs on DFL buses, NXP i.MX8DL, HiSilicon Kunpeng,
    MediaTek MT8195,

53b776c77a netfs: Miscellaneous fixes 
Fix some miscellaneous things in the new netfs lib[1]:

 (1) The kerneldoc for netfs_readpage() shouldn't say netfs_page().

 (2) netfs_readpage() can get an integer overflow on 32-bit when it
     multiplies page_index(page) by PAGE_SIZE.  It should use
     page_file_offset() instead.

 (3) netfs_write_begin() should use page_offset() to avoid the same
     overflow.

Note that netfs_readpage() needs to use page_file_offset() rather than
page_offset() as it may see swap-over-NFS.

 "These update the ACPICA code in the kernel to the most recent upstream
  revision including (but not limited to) new material introduced in the
  6.4 version of the spec, update message printing in the ACPI-related
  code, address a few issues and clean up code in a number of places.

  Specifics:

   - Update ACPICA code in the kernel to upstream revision 20210331

     some related code cleanups (Rafael Wysocki).

   - Modify the device enumeration code to turn off all of the unused
     ACPI power resources at the end (Rafael Wysocki).

   - Change the ACPI power resources handling code to turn off unused
     ACPI power resources without checking their status which should not
     be necessary by the spec (Rafael Wysocki).

47080f2286 hwmon updates for v5.13 
The most notable change is the removal of the amd_energy driver. It was
 rendered all but unusable by making its attributes privileged-only to work
 around a security issue. A suggested remedy was rejected by AMD, so the
 only real solution was to remove the driver. For the future, we'll have
 to make sure that no privileged-access-only drivers are accepted into the
 hwmon subsystem in the first place. The hwmon ABI document was updated
 accordingly.
 
 Other changes:
 
 PMBus drivers:
 - Added driver for MAX15301
 - Added driver for BluTek BPA-RS600
 - Added driver for fsp-3y PSUs and PDUs
 - Added driver for Infineon IR36021
 - Added driver for ST STPDDC60
 - Added support for TI TPS53676 to tps53679 driver
 - Introduced PMBUS symbol namespace
   This was made necessary by a suggestion to use its exported functions
   from outside the hwmon subsystem.
 - Minor improvements and bug fixes
 
 New drivers:
 - Driver for NZXT Kraken X42/X52/X62/X72
 
 Driver enhancements:
 - Added support for Intel D5005 to intel-m10-bmc-hwmon driver
 - Added support for NCT6686D to nct6683 driver
 
 Other:
 - Converted sch5627 and amd9240 drivers to hwmon_device_register_with_info()
 - Added support for fan drawers capability and present registers to mlxreg-fan
   driver
 - Added Dell Latitude E7440 to fan control whitelist in dell-smm driver
 - Replaced snprintf in show functions with sysfs_emit
   Done with coccinelle script for all drivers to preempt endless per-driver
   submissions of the same change.
 - Use kobj_to_dev()
   Another coccinelle based change to preempt endless per-driver submissions
   of the same change.
 - Various minor fixes and improvements

3d14ec1fe6 iov_iter: Four fixes for ITER_XARRAY 
Fix four things[1] in the patch that adds ITER_XARRAY[2]:

 (1) Remove the address_space struct predeclaration.  This is a holdover
     from when it was ITER_MAPPING.

 (2) Fix _copy_mc_to_iter() so that the xarray segment updates count and
     iov_offset in the iterator before returning.

 (3) Fix iov_iter_alignment() to not loop in the xarray case.  Because the
     middle pages are all whole pages, only the end pages need be
     considered - and this can be reduced to just looking at the start
     position in the xarray and the iteration size.

 (4) Fix iov_iter_advance() to limit the size of the advance to no more
     than the remaining iteration size.

Pull btrfs updates from David Sterba:
 "The updates this time are mostly stabilization, preparation and minor
  improvements.

  User visible improvements:

   - readahead for send, improving run time of full send by 10% and for
     incremental by 25%

   - make reflinks respect O_SYNC, O_DSYNC and S_SYNC flags

   - export supported sectorsize values in sysfs (currently only page
     size, more once full subpage support lands)

   - more graceful errors and warnings on 32bit systems when logical
     addresses for metadata reach the limit posed by unsigned long in
     page::index
      - error: fail mount if there's a metadata block beyond the limit
      - error: new metadata block would be at unreachable address
      - warn when 5/8th of the limit is reached, for 4K page systems
        it's 10T, for 64K page it's 160T

   - zoned mode
      - relocated zones get reset at the end instead of discard
      - automatic background reclaim of zones that have 75%+ of unusable
        space, the threshold is tunable in sysfs

  Fixes:

   - fsync and tree mod log fixes

   - fix inefficient preemptive reclaim calculations

   - fix exhaustion of the system chunk array due to concurrent
     allocations

   - fix fallback to no compression when racing with remount

   - preemptive fix for dm-crypt on zoned device that does not properly
     advertise zoned support

  Core changes:

   - add inode lock to synchronize mmap and other block updates (eg.
     deduplication, fallocate, fsync)

   - kmap conversions to new kmap_local API

   - subpage support (continued)
      - new helpers for page state/extent buffer tracking
      - metadata changes now support read and write

   - error handling through out relocation call paths

   - many other cleanups and code simplifications"

Pull erofs updates from Gao Xiang:
 "In this cycle, we would like to introduce a new feature called big
  pcluster so EROFS can compress file data into more than 1 fs block and
  different pcluster size can be selected for each (sub-)files by
  design.

  The current EROFS test results on my laptop are [1]:

  which has been verified but I'd like warn it as experimental for a
  while. This matches erofs-utils dev branch and I'll also release a new
  userspace version for this later.

  Apart from that, several improvements are also included: eg complete a
  missing case for inplace I/O, optimize endio decompression logic for
  non-atomic contexts and support adjustable sliding window size, ... In
  addition to those, there are some cleanups as always.

  Summary:

   - avoid memory failure when applying rolling decompression

   - optimize endio decompression logic for non-atomic contexts

   - complete a missing case which can be safely selected for inplace
     I/O and thus decreasing more memory footprint

   - check unsupported on-disk inode i_format strictly

   - support adjustable lz4 sliding window size to decrease runtime

   - support on-disk compression configurations

   - support big pcluster decompression

   - several code cleanups / spelling correction"

Pull file locking updates from Jeff Layton:
 "When we reworked the blocked locks into a tree structure instead of a
  flat list a few releases ago, we lost the ability to see all of the
  file locks in /proc/locks. Luo's patch fixes it to dump out all of the
  blocked locks instead, which restores the full output.

  This changes the format of /proc/locks as the blocked locks are shown
  at multiple levels of indentation now, but lslocks (the only common
  program I've ID'ed that scrapes this info) seems to be OK with that.

  Tian also contributed a small patch to remove a useless assignment"

0c85556318 ARM: platform support for Apple M1 
The Apple M1 is the processor used it all current generation Apple
 Macintosh computers. Support for this platform so far is rudimentary,
 but it boots and can use framebuffer and serial console over a special
 USB cable.
 
 Support for several essential on-chip devices (USB, PCIe, IOMMU, NVMe)
 is work in progress but was not ready in time.
 
 A very detailed description of what works is in the merge commit
 and on the AsahiLinux wiki.

6b0fbc540c ARM: platform support for Nuvoton WPCM450 
The Nuvoton WPCM450 BMC is an older chip based on the ARM926 CPU core
 that remains in use on Supermicro X9 server boards among others. Support
 gets added for a particular server board using this SoC along with the
 basic platform bringup.
 
 As the platform is a predecessor to the npcm7xx platform we already
 support, it is added to the same directory, despite using a different
 name. It also seems to be related to the older w90x900/nuc9xx platform
 that was removed last year.

f7857bf374 ARM: devicetree changes for 5.13 
There are six new SoCs added this time. Apple M1 and Nuvoton WPCM450
 have separate branches because they are new SoC families that require
 changes outside of device tree files. The other four are variations of
 already supported chips and get merged through this branch:
 
  - STMicroelectronics STM32H750 is one of many variants of STM32
    microcontrollers based on the Cortex-M7 core. This is particularly
    notable since we rarely add support for new MMU-less chips
    these days. In this case, the board that gets added along with
    the platform is not a SoC reference platform but the "Art Pi"
    (https://art-pi.gitee.io/website/) machine that was originally design
    for the RT-Thread RTOS.
 
  - NXP i.MX8QuadMax is a variant of the growing i.MX8 embedded/industrial
    SoC family, using two Cortex-A72 and four Cortex-A53 cores. It
    gets added along with its reference board, the "NXP i.MX8QuadMax
    Multisensory Enablement Kit".
 
  - Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon 7c)
    that is used in some Chromebooks and Windows laptops. Only a reference
    board is added for the moment.
 
  - TI AM64x Sita4ra is a new version of the K3 SoC family for industrial
    control, motor control, remote IO, IoT gateway etc., similar to the
    older AM65x family. Two reference machines are added alongside.
 
 Among the newly added machines, there is a very clear skew towards 64-bit
 machines now, with 12 32-bit machines compared to 23 64-bit machines. The
 full list sorted by SoC is:
 
  - ASpeed AST2500 BMC: ASRock E3C246D4I Xeon server board
  - Allwinner A10: Topwise A721 Tablet
  - Amlogic GXL: MeCool KII TV box
  - Amlogic GXM: Mecool KIII, Minix Neo U9-H TV boxes
  - Broadcom BCM4908: TP-Link Archer C2300 V1 router
  - MStar SSD202D: M5Stack UnitV2 camera
  - Marvell Armada 38x: ATL-x530 ethernet switch
  - Mediatek MT8183 Chromebooks: Lenovo 10e, Acer Spin 311,
    Asus Flip CM3, Asus Detachable CM3
  - Mediatek MT8516/MT8183: OLogic Pumpkin Board
  - NXP i.MX7: reMarkable Tablet
  - NXP i.MX8M: Kontron pitx-imx8m, Engicam i.Core MX8M Mini
  - Nuvoton NPCM730: Quanta GBS BMC
  - Qualcomm X55: Telit FN980 TLB SoM, Thundercomm TurboX T55 SoM
  - Qualcomm MSM8998: OnePlus 5/5T phones
  - Qualcomm SM8350: Snapdragon 888 Mobile Hardware Development Kit
  - Rockchip RK3399: NanoPi R4S board
  - STM32MP1: Engicam MicroGEA STM32MP1 MicroDev 2.0 and SOM,
    EDIMM2.2 Starter Kit, Carrier, SOM
  - TI AM65: Siemens SIMATIC IOT2050 gateway
 
 There is notable work going into extending already supported machines
 and SoCs:
 
  - ASpeed AST2500
  - Allwinner A23, A83t, A31, A64, H6
  - Amlogic G12B
  - Broadcom BCM4908
  - Marvell Armada 7K/8K/CN91xx
  - Mediatek MT6589, MT7622, MT8173, MT8183, MT8195
  - NXP i.MX8Q, i.MX8MM, i.MX8MP
  - Qualcomm MSM8916, SC7180, SDM845, SDX55, SM8350
  - Renesas R-Car M3, V3U
  - Rockchip RK3328, RK3399
  - STEricsson U8500
  - STMicroelectronics STM32MP141
  - Samsung Exynos 4412
  - TI K3-AM65, K3-J7200
  - TI OMAP3
 
 Among the treewide cleanups and bug fixes, two parts stand out:
 
  - There are a number of cleanups for issues pointed out by 'make
    dtbs_check' this time, and I expect more to come in the future as we
    increasingly check for regressions.
 
  - After a change to the MMC subsystem that can lead to unpredictable
    device numbers, several platforms add 'aliases' properties for these
    to give each MMC controller a fixed number.

Merge tag 'arm-dt-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM devicetree updates from Arnd Bergmann:
 "There are six new SoCs added this time.

  Apple M1 and Nuvoton WPCM450 have separate branches because they are
  new SoC families that require changes outside of device tree files.
  The other four are variations of already supported chips and get
  merged through this branch:

   - STMicroelectronics STM32H750 is one of many variants of STM32
     microcontrollers based on the Cortex-M7 core.

     This is particularly notable since we rarely add support for new
     MMU-less chips these days. In this case, the board that gets added
     along with the platform is not a SoC reference platform but the
     "Art Pi" (https://art-pi.gitee.io/website/) machine that was
     originally design for the RT-Thread RTOS.

   - NXP i.MX8QuadMax is a variant of the growing i.MX8
     embedded/industrial SoC family, using two Cortex-A72 and four
     Cortex-A53 cores.

     It gets added along with its reference board, the "NXP i.MX8QuadMax
     Multisensory Enablement Kit".

   - Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon
     7c) that is used in some Chromebooks and Windows laptops.

     Only a reference board is added for the moment.

   - TI AM64x Sita4ra is a new version of the K3 SoC family for
     industrial control, motor control, remote IO, IoT gateway etc.,
     similar to the older AM65x family.

     Two reference machines are added alongside.

  Among the newly added machines, there is a very clear skew towards
  64-bit machines now, with 12 32-bit machines compared to 23 64-bit
  machines. The full list sorted by SoC is:

   - ASpeed AST2500 BMC: ASRock E3C246D4I Xeon server board
   - Allwinner A10: Topwise A721 Tablet
   - Amlogic GXL: MeCool KII TV box
   - Amlogic GXM: Mecool KIII, Minix Neo U9-H TV boxes
   - Broadcom BCM4908: TP-Link Archer C2300 V1 router
   - MStar SSD202D: M5Stack UnitV2 camera
   - Marvell Armada 38x: ATL-x530 ethernet switch
   - Mediatek MT8183 Chromebooks: Lenovo 10e, Acer Spin 311, Asus Flip
     CM3, Asus Detachable CM3
   - Mediatek MT8516/MT8183: OLogic Pumpkin Board
   - NXP i.MX7: reMarkable Tablet
   - NXP i.MX8M: Kontron pitx-imx8m, Engicam i.Core MX8M Mini
   - Nuvoton NPCM730: Quanta GBS BMC
   - Qualcomm X55: Telit FN980 TLB SoM, Thundercomm TurboX T55 SoM
   - Qualcomm MSM8998: OnePlus 5/5T phones
   - Qualcomm SM8350: Snapdragon 888 Mobile Hardware Development Kit
   - Rockchip RK3399: NanoPi R4S board
   - STM32MP1: Engicam MicroGEA STM32MP1 MicroDev 2.0 and SOM, EDIMM2.2
     Starter Kit, Carrier, SOM
   - TI AM65: Siemens SIMATIC IOT2050 gateway

  There is notable work going into extending already supported machines
  and SoCs:

   - ASpeed AST2500
   - Allwinner A23, A83t, A31, A64, H6
   - Amlogic G12B
   - Broadcom BCM4908
   - Marvell Armada 7K/8K/CN91xx
   - Mediatek MT6589, MT7622, MT8173, MT8183, MT8195
   - NXP i.MX8Q, i.MX8MM, i.MX8MP
   - Qualcomm MSM8916, SC7180, SDM845, SDX55, SM8350
   - Renesas R-Car M3, V3U
   - Rockchip RK3328, RK3399
   - STEricsson U8500
   - STMicroelectronics STM32MP141
   - Samsung Exynos 4412
   - TI K3-AM65, K3-J7200
   - TI OMAP3

  Among the treewide cleanups and bug fixes, two parts stand out:

   - There are a number of cleanups for issues pointed out by 'make
     dtbs_check' this time, and I expect more to come in the future as
     we increasingly check for regressions.

   - After a change to the MMC subsystem that can lead to unpredictable
     device numbers, several platforms add 'aliases' properties for
     these to give each MMC controller a fixed number"

  - ti-sysc needs iorange check improved when the interconnect target module
    has no control registers listed
  - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
    issues with missing resources and unnecessary deferred probe
  - ti-sysc debug option can now detect more devices
  - ti-sysc now warns if an old incomplete devicetree data is found as we
    now rely on it being complete for am3 and 4
  - soc init code needs to check for prcm and prm nodes for omap4/5 and dra7
  - omap-prm driver needs to enable autoidle retention support for omap4
  - omap5 clocks are missing gpmc and ocmc clock registers
  - pci-dra7xx now needs to use builtin_platform_driver instead of using
    builtin_platform_driver_probe for deferred probe to work
 
 Raspberry Pi:
  - Fix-up all RPi firmware drivers so as for unbind to happen in an
    orderly fashion
  - Support for RPi's PoE hat PWM bus
 
 Qualcomm
  - Improved detection for SCM calling conventions
