A common use case for regulators is to supply a reference voltage to an
analog input or output device. This adds a new devres API to get,
enable, and get the voltage in a single call. This allows eliminating
boilerplate code in drivers that use reference supplies in this way.

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.

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().

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, OTHER than some merge issues with other trees that should be
obvious when you hit them (block tree deletes a driver that this tree
modifies, iommufd tree modifies code that this tree also touches). If
there are merge problems with these trees, please let me know.

- 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

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.
- 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.
There's a cross tree merge with the I2C tree in order to use the new
i2c_client_get_device_id() helper in the conversions to probe_new().

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"

- The beginnings of a set of translations into Spanish, headed up by Carlos
Bilbao.
- More Chinese translations.
- A change to the Sphinx "alabaster" theme by default for HTML generation.
Unlike the previous default (Read the Docs), alabaster is shipped with
Sphinx by default, reducing the number of other dependencies that need to
be installed. It also (IMO) produces a cleaner and more readable result.
- The ability to render the documentation into the texinfo format

regulator modes, simplifying the interface for configuring modes to not
take account of the voltage and as a side effect resolving a
bootstrapping issue on systems where we can't read the voltage from the
regulator. Otherwise it's been quite a quiet release with some new
drivers and a devm helper:
- Make the load handling in the Qualcomm RPMH regulators much more
idiomatic and general cleanups to the handling of load configuration.
- devm helper for a combined get and enable operation.
- Support for MediaTek MT6331, Qualcomm PM660, 660L and PM6125, Texas

This change introduces a device-managed variant to the
iio_map_array_register() function. It's a simple implementation of calling
iio_map_array_register() and registering a callback to
iio_map_array_unregister() with the devm_add_action_or_reset().
The function uses an explicit 'dev' parameter to bind the unwinding to. It
could have been implemented to implicitly use the parent of the IIO device,
however it shouldn't be too expensive to callers to just specify to which
device object to bind this unwind call.
It would make the API a bit more flexible.

This contains mostly various fixes, cleanups and some conversions to the
atomic API. One noteworthy change is that PWM consumers can now pass a
hint to the PWM core about the PWM usage, enabling PWM providers to
implement various optimizations.
There's also a fair bit of simplification here with the addition of some
device-managed helpers as well as unification between the DT and ACPI
firmware interfaces.

Pull pwm updates from Thierry Reding:
"This contains mostly various fixes, cleanups and some conversions to
the atomic API. One noteworthy change is that PWM consumers can now
pass a hint to the PWM core about the PWM usage, enabling PWM
providers to implement various optimizations.
There's also a fair bit of simplification here with the addition of
some device-managed helpers as well as unification between the DT and
ACPI firmware interfaces"

Since the macro was introduced in 2019 (commit bb6243b4f7 ("drivers:
platform: provide devm_platform_ioremap_resource_wc()") there is only a
single user which hardly justifies the function for the small task it
provides.
So drop the helper and open-code it in the only user. Adapt the non-wc
case accordingly.

The Apple M1 is the processor used it all current generation Apple

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.

ARM64 currently defaults to posted MMIO (nGnRE), but some devices
require the use of non-posted MMIO (nGnRnE). Introduce a new ioremap()
variant to handle this case. ioremap_np() returns NULL on arches that
do not implement this variant.
sparc64 is the only architecture that needs to be touched directly,
because it includes neither of the generic io.h or iomap.h headers.
This adds the IORESOURCE_MEM_NONPOSTED flag, which maps to this
variant and marks a given resource as requiring non-posted mappings.
This is implemented in the resource system because it is a SoC-level
requirement, so existing drivers do not need special-case code to pick
this ioremap variant.
Then this is implemented in devres by introducing devm_ioremap_np(),
and making devm_ioremap_resource() automatically select this variant
when the resource has the IORESOURCE_MEM_NONPOSTED flag set.

This change does a conversion of the devm_iio_dmaengine_buffer_alloc() to
devm_iio_dmaengine_buffer_setup(). This will allocate an IIO DMA buffer and
attach it to the IIO device, similar to devm_iio_triggered_buffer_setup()
(though the underlying code is different, the final logic is the same).
Since the only user of the devm_iio_dmaengine_buffer_alloc() was the
adi-axi-adc driver, this change does the replacement in a single go in the
driver.

At this point all drivers should use devm_iio_kfifo_buffer_setup() instead
of manually allocating via devm_iio_kfifo_allocate() and assigning ops and
modes.
With this change, the devm_iio_kfifo_allocate() will be made private to the
IIO core, since all drivers should call either
devm_iio_kfifo_buffer_setup() or devm_iio_triggered_buffer_setup() to
create a kfifo buffer.
