Pull spi updates from Mark Brown:
 "This release sees some exciting changes from David Lechner which
  implements some optimisations that have been talked about for a long
  time which allows client drivers to pre-prepare SPI messages for
  repeated or low latency use. This lets us move work out of latency
  sensitive paths and avoid repeating work for frequently performed
  operations. As well as being useful in itself this will also be used
  in future to allow controllers to directly trigger SPI operations (eg,
  from interrupts).

  Otherwise this release has mostly been focused on cleanups, plus a
  couple of new devices:

   - Support for pre-optimising messages

   - A big set of updates from Uwe Kleine-König moving drivers to use
     APIs with more modern terminology for controllers

   - Major overhaul of the s3c64xx driver

   - Support for Google GS101 and Samsung Exynos850"

<title>pwm: Provide pwmchip_alloc() function and a devm variant of it</title>

<id>024913dbf99f06f09d5c06c940ca39821697d41c</id>
<content type='text'>
This function allocates a struct pwm_chip and driver data. Compared to
the status quo the split into pwm_chip and driver data is new, otherwise
it doesn't change anything relevant (yet).

The intention is that after all drivers are switched to use this
allocation function, its possible to add a struct device to struct
pwm_chip to properly track the latter's lifetime without touching all
drivers again. Proper lifetime tracking is a necessary precondition to
introduce character device support for PWMs (that implements atomic
setting and doesn't suffer from the sysfs overhead of the /sys/class/pwm
userspace support).

The new function pwmchip_priv() (obviously?) only works for chips
allocated with pwmchip_alloc().

There is no krealloc_array equivalent in devres. Users would have to
do their own multiplication overflow check so provide one.

<title>driver core: bus: mark the struct bus_type for sysfs callbacks as constant</title>

struct bus_type should never be modified in a sysfs callback as there is
nothing in the structure to modify, and frankly, the structure is almost
never used in a sysfs callback, so mark it as constant to allow struct
bus_type to be moved to read-only memory.

Pull driver core updates from Greg KH:
 "Here is the set of driver core and kernfs changes for 6.2-rc1.

  The "big" change in here is the addition of a new macro,
  container_of_const() that will preserve the "const-ness" of a pointer
  passed into it.

  The "problem" of the current container_of() macro is that if you pass
  in a "const *", out of it can comes a non-const pointer unless you
  specifically ask for it. For many usages, we want to preserve the
  "const" attribute by using the same call. For a specific example, this
  series changes the kobj_to_dev() macro to use it, allowing it to be
  used no matter what the const value is. This prevents every subsystem
  from having to declare 2 different individual macros (i.e.
  kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce
  the const value at build time, which having 2 macros would not do
  either.

  The driver for all of this have been discussions with the Rust kernel
  developers as to how to properly mark driver core, and kobject,
  objects as being "non-mutable". The changes to the kobject and driver
  core in this pull request are the result of that, as there are lots of
  paths where kobjects and device pointers are not modified at all, so
  marking them as "const" allows the compiler to enforce this.

  So, a nice side affect of the Rust development effort has been already
  to clean up the driver core code to be more obvious about object
  rules.

  All of this has been bike-shedded in quite a lot of detail on lkml
  with different names and implementations resulting in the tiny version
  we have in here, much better than my original proposal. Lots of
  subsystem maintainers have acked the changes as well.

  Other than this change, included in here are smaller stuff like:

   - kernfs fixes and updates to handle lock contention better

   - vmlinux.lds.h fixes and updates

   - sysfs and debugfs documentation updates

   - device property updates

  All of these have been in the linux-next tree for quite a while with
  no problems"

* tag 'driver-core-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (58 commits)
  device property: Fix documentation for fwnode_get_next_parent()

  usb.h: take advantage of container_of_const()

Pull USB and Thunderbolt driver updates from Greg KH:
 "Here is the large set of USB and Thunderbolt driver changes for
  6.2-rc1. Overall, thanks to the removal of a driver, more lines were
  removed than added, a nice change. Highlights include:

   - removal of the sisusbvga driver that was not used by anyone anymore

   - minor thunderbolt driver changes and tweaks

   - chipidea driver updates

   - usual set of typec driver features and hardware support added

   - musb minor driver fixes

   - fotg210 driver fixes, bringing that hardware back from the "dead"

   - minor dwc3 driver updates

   - addition, and then removal, of a list.h helper function for many
     USB and other subsystem drivers, that ended up breaking the build.
     That will come back for 6.3-rc1, it missed this merge window.

   - usual xhci updates and enhancements

   - usb-serial driver updates and support for new devices

   - other minor USB driver updates

  All of these have been in linux-next for a while with no reported
  problems"

Pull regulator updates from Mark Brown:
 "Quite a quiet release for regulator, the diffstat is dominated by the
  I2C migration to probe_new() and the newly added MT6357 driver. We've
  just one framework addition and the rest is all new device support,
  fixes and cleanups.

  The framework addition is an API for requesting all regulators defined
  in DT, this isn't great practice but has reasonable applications when
  there is generic code handling devices on buses where the bus
  specification doesn't include power. The immediate application is MDIO
  but I believe there's others, it's another API that'll need an eye
  keeping on it for undesirable usage.

  Summary:

    - An API for requesting all regulators defined in DT

    - Conversion of lots of drivers to the I2C probe_new() API

    - Support for Mediatek MT6357, Qualcomm PM8550, PMR735a and Richtek
      RT6190"
