[Note: the code is mostly from Laurent but the patch description is from Tomi]
The media_pipeline_start() and media_pipeline_stop() functions use the
media graph walk API to traverse the graph and validate the pipeline.
The graph walk traverses the media graph following links between the
entities.
Also, while the pipeline can't change between the start and stop calls,
the graph is walked again from scratch at stop time, or any time a
driver needs to inspect the pipeline.
With the upcoming multiplexed streams support we will need a bit more
intelligent pipeline construction, as e.g. two independent streams may
be passing through a single entity via separate pads in which case
those pads should not be part of the same pipeline.
This patch essentially rewrites the media_pipeline_start/stop so that
a pipeline is defined as a set of pads instead of entities and the media
graph traversal considers the pad interdependencies when choosing which
links to follow.
Currently all the entity's pads are considered as interdependent. This
means that the behavior with all the current drivers stays the same, but
in the future we can define a more fine-grained pipeline construction.
Additionally the media pipeline's pads are cached at
media_pipeline_start() time, and re-used at media_pipeline_stop() which
avoid the need to re-walk the whole graph as the previous implementation
did.
Also, caching pads in the pipeline can serve in the future as the
foundation to provide a better API than the media graph walk to drivers
to iterate over pads and entities in the pipeline.
Note that the old media_pipeline_start/stop used the media graph walk
API. The new version does not use the media graph walk API, but instead
a new implementation.
There are two reasons for not changing the graph walk: it proved to be
rather difficult to change the graph walk to have the features
implemented in this patch, and second, this keeps the backward
compatibility of the graph walk as there are users of the graph walk API
The long term plan is that all the existing code would be converted to
use the new cached pipeline, thus allowing us to remove the graph walk.

Here is the big set of tty and serial driver changes for 6.0-rc1.
It was delayed from last week as I wanted to make sure the last commit
here got some good testing in linux-next and elsewhere as it seemed to
show up only late in testing for some reason.
Nothing major here, just lots of cleanups from Jiri and Ilpo to make the
tty core cleaner (Jiri) and the rs485 code simpler to use (Ilpo). Also
included in here is the obligatory n_gsm updates from Daniel Starke and
lots of tiny driver updates and minor fixes and tweaks for other smaller
serial drivers.
Full details are in the shortlog.
All of these have been in linux-next for a while with no reported
problems.

boilerplate text. Also included in here are a few other minor updates,
2 USB files, and one Documentation file update to get the SPDX lines
correct.

Here is the big set of staging driver patches for 6.0-rc1.
Another round where we removed more lines of code than added, always a
nice progression. Some of that came from the movement of the vme code
back into staging, and removal of some other of the vme driver code as
there are no known users and it is very obsolete and unmaintained. It
can be added back easily if someone offers to maintain it.
Other than that this merge has lots of little things:
- huge cleanups for r8188eu driver
- minor cleanups for other wifi drivers
- tiny loop fixes for greybus code
- other small coding style fixes
All of these have been in linux-next for a while with no reported
issues.

A recent snafu where Intel ignored upstream feedback on a firmware
change, led to a late rc6 fix being required. In order to avoid this
in the future we should document some expectations around
linux-firmware.
I was originally going to write this for drm, but it seems quite generic
advice.

While it's a lot of text, it always helps to keep it up to date when
it's by the source. (And not in a separate file.)
The documentation tooling also makes sure that all members of the
structure are documented. (If not, it complains loudly.)
Finally, there needs to be no comments inlined in the structure, so they
are dropped as they are superfluous now.
The compilation time of this header (tested with serial_core.c) didn't
change in my testing at all.

Most of the callers of vfio_pin_pages() want "struct page *" and the
low-level mm code to pin pages returns a list of "struct page *" too.
So there's no gain in converting "struct page *" to PFN in between.
Replace the output parameter "phys_pfn" list with a "pages" list, to
simplify callers. This also allows us to replace the vfio_iommu_type1
implementation with a more efficient one.
And drop the pfn_valid check in the gvt code, as there is no need to
do such a check at a page-backed struct page pointer.
For now, also update vfio_iommu_type1 to fit this new parameter too.

The vfio_pin/unpin_pages() so far accepted arrays of PFNs of user IOVA.
Among all three callers, there was only one caller possibly passing in
a non-contiguous PFN list, which is now ensured to have contiguous PFN
inputs too.
Pass in the starting address with "iova" alone to simplify things, so
callers no longer need to maintain a PFN list or to pin/unpin one page
at a time. This also allows VFIO to use more efficient implementations
of pin/unpin_pages.
For now, also update vfio_iommu_type1 to fit this new parameter too,
while keeping its input intact (being user_iova) since we don't want
to spend too much effort swapping its parameters and local variables
at that level.

There's only one caller that checks its return value with a WARN_ON_ONCE,
while all other callers don't check the return value at all. Above that,
an undo function should not fail. So, simplify the API to return void by
embedding similar WARN_ONs.
Also for users to pinpoint which condition fails, separate WARN_ON lines,
yet remove the "driver->ops->unpin_pages" check, since it's unreasonable
for callers to unpin on something totally random that wasn't even pinned.
And remove NULL pointer checks for they would trigger oops vs. warnings.
Note that npage is already validated in the vfio core, thus drop the same
check in the type1 code.

CXL 2.0 allows for dynamic provisioning of new memory regions (system
physical address resources like "System RAM" and "Persistent Memory").
Whereas DDR and PMEM resources are conveyed statically at boot, CXL
allows for assembling and instantiating new regions from the available
capacity of CXL memory expanders in the system.
Sysfs with an "echo $region_name > $create_region_attribute" interface
is chosen as the mechanism to initiate the provisioning process. This
was chosen over ioctl() and netlink() to keep the configuration
interface entirely in a pseudo-fs interface, and it was chosen over
configfs since, aside from this one creation event, the interface is
read-mostly. I.e. configfs supports cases where an object is designed to
be provisioned each boot, like an iSCSI storage target, and CXL region
creation is mostly for PMEM regions which are created usually once
per-lifetime of a server instance. This is an improvement over nvdimm
that pre-created "seed" devices that tended to confuse users looking to
determine which devices are active and which are idle.
Recall that the major change that CXL brings over previous persistent
memory architectures is the ability to dynamically define new regions.
Compare that to drivers like 'nfit' where the region configuration is
statically defined by platform firmware.
Regions are created as a child of a root decoder that encompasses an
address space with constraints. When created through sysfs, the root
decoder is explicit. When created from an LSA's region structure a root
decoder will possibly need to be inferred by the driver.
Upon region creation through sysfs, a vacant region is created with a
unique name. Regions have a number of attributes that must be configured
before the region can be bound to the driver where HDM decoder program
is completed.
An example of creating a new region:
- Allocate a new region name:
region=$(cat /sys/bus/cxl/devices/decoder0.0/create_pmem_region)
- Create a new region by name:
while
region=$(cat /sys/bus/cxl/devices/decoder0.0/create_pmem_region)
! echo $region > /sys/bus/cxl/devices/decoder0.0/create_pmem_region
do true; done
- Region now exists in sysfs:

The newly added media_entity_remote_source_pad_unique() helper function
handles use cases where the entity has a link enabled uniqueness
constraint covering all pads. There are use cases where the constraint
covers a specific pad only. Add a new media_pad_remote_pad_unique()
function to handle this. It operates as
media_entity_remote_source_pad_unique(), but on a given pad instead of
on the entity.

The media_entity_remote_pad_first() helper function returns the first
remote pad it finds connected to a given pad. Beside being possibly
non-deterministic (as it stops at the first enabled link), the fact that
it returns the first match makes it unsuitable for drivers that need to
guarantee that a single link is enabled, for instance when an entity can
process data from one of multiple sources at a time.
For those use cases, add a new helper function,
media_entity_remote_pad_unique(), that operates on an entity and returns
a remote pad, with a guarantee that only one link is enabled. To ease
its use in drivers, also add an inline wrapper that locates source pads
specifically. A wrapper that locates sink pads can easily be added when
needed.

Drivers typically extend the v4l2_async_subdev structure by embedding it
in a driver-specific structure, to store per-subdev custom data. The
v4l2_async_subdev instances are freed by the v4l2-async framework, which
makes this mechanism cumbersome to use safely when custom data needs
special treatment to be destroyed (such as freeing additional memory, or
releasing references to kernel objects).
To ease this, add a .destroy() operation to the
v4l2_async_notifier_operations structure. The operation is called right
before the v4l2_async_subdev is freed, giving drivers a chance to
destroy data if needed.

Add support for RS-485 multipoint addressing using 9th bit [*]. The
addressing mode is configured through ->rs485_config().
ADDRB in termios indicates 9th bit addressing mode is enabled. In this
mode, 9th bit is used to indicate an address (byte) within the

->rs485_config() that is also responsible for setting the destination and
receiver (filter) addresses.
Add traps to detect unwanted changes to struct serial_rs485 layout using

[*] Technically, RS485 is just an electronic spec and does not itself
specify the 9th bit addressing mode but 9th bit seems at least
"semi-standard" way to do addressing with RS485.

Since commit 31f6bd7fad ("serial: Store character timing information
to uart_port"), per frame timing information is available on uart_port.
Uart port's timeout can be derived from frame_time by multiplying with
fifosize.
Most callers of uart_poll_timeout are not made under port's lock. To be
on the safe side, make sure frame_time is only accessed once. As
fifo_size is effectively a constant, it shouldn't cause any issues.

Implement DRM's aperture helpers under video/ for sharing with other
sub-systems. Remove DRM-isms from the interface. The helpers track
the ownership of framebuffer apertures and provide hand-over from
firmware, such as EFI and VESA, to native graphics drivers.
Other subsystems, such as fbdev and vfio, also have to maintain ownership
of framebuffer apertures. Moving DRM's aperture helpers to a more public
location allows all subsystems to interact with each other and share a
common implementation.
The aperture helpers are selected by the various firmware drivers within
DRM and fbdev, and the VGA text-console driver.
The original DRM interface is kept in place for use by DRM drivers.
v3:
* prefix all interfaces with aperture_ (Javier)
* rework and simplify documentation (Javier)
* rename struct dev_aperture to struct aperture_range

When SSAM client devices have been (physically) hot-removed,
communication attempts with those devices may fail and time out. This
can even extend to event notifiers, due to which timeouts may occur
during device removal, slowing down that process.
Add a parameter to the notifier unregister function that allows skipping
communication with the EC to prevent this. Furthermore, add wrappers for
registering and unregistering notifiers belonging to SSAM client devices
that automatically check if the device has been marked as hot-removed
and communication should be avoided.
Note that non-SSAM client devices can generally not be hot-removed, so
also add a convenience wrapper for those, defaulting to allow
communication.

The VME subsystem graduated from staging into a top-level subsystem in
2012, with commit db3b9e990e ("Staging: VME: move VME drivers out of
staging") stating:
The VME device drivers have not moved out yet due to some API
questions they are still working through, that should happen soon,
hopefully.
However, this never happened: maintenance of drivers/vme effectively
stopped in 2017, with all subsequent changes being treewide cleanups.
No hardware driver remains in staging, only the limited user-level
access, and I just removed one of the two bridge drivers and the only
remaining board.
drivers/staging/vme/devices/ was recently moved to
drivers/staging/vme_user/, but as the vme_user driver is the only one
remaining for this subsystem, it is easier to just move the remaining
three source files into this directory rather than keeping the original
hierarchy.

Sanitize serial_rs485 struct before calling into rs485_setup. The
drivers provide supported_rs485 to help sanitization of the fields.
If neither of SER_RS485_RTS_ON_SEND or SER_RS485_RTS_AFTER_SEND
supported, don't pretend they can be set to sane settings but clear
them both instead. If only one of them is supported it may look
tempting to use the one driver supports to set the other, however, the
userspace does not have that information readily available so it
wouldn't be helpful.
While adjusting the documentation, remove also the claim that
TIOCGRS485 would call driver specific code. In reality, it does nothing
else than copies the stored serial_rs485 structure from uart_port to
userspace.

Here is the set of driver core changes for 5.19-rc1.
Note, I'm not really happy with this pull request as-is, see below for
details, but overall this is all good for everything but a small set of
systems, which we have a fix for already.
Lots of tiny driver core changes and cleanups happened this cycle,
but the two major things were:
- firmware_loader reorganization and additions including the
ability to have XZ compressed firmware images and the ability
for userspace to initiate the firmware load when it needs to,
instead of being always initiated by the kernel. FPGA devices
specifically want this ability to have their firmware changed
over the lifetime of the system boot, and this allows them to
work without having to come up with yet-another-custom-uapi
interface for loading firmware for them.
- physical location support added to sysfs so that devices that
know this information, can tell userspace where they are
located in a common way. Some ACPI devices already support
this today, and more bus types should support this in the
future.
Smaller changes included:
- driver_override api cleanups and fixes
- error path cleanups and fixes
- get_abi script fixes
- deferred probe timeout changes.
It's that last change that I'm the most worried about. It has been
reported to cause boot problems for a number of systems, and I have a
tested patch series that resolves this issue. But I didn't get it
merged into my tree before 5.18-final came out, so it has not gotten any
linux-next testing.
I'll send the fixup patches (there are 2) as a follow-on series to this
pull request if you want to take them directly, _OR_ I can just revert
the probe timeout changes and they can wait for the next -rc1 merge
cycle. Given that the fixes are tested, and pretty simple, I'm leaning
toward that choice. Sorry this all came at the end of the merge window,
I should have resolved this all 2 weeks ago, that's my fault as it was
in the middle of some travel for me.
All have been tested in linux-next for weeks, with no reported issues
other than the above-mentioned boot time outs.

Here is the big set of tty and serial driver updates for 5.19-rc1.
Lots of tiny cleanups in here, the major stuff is:
- termbit cleanups and unification by Ilpo. A much needed
change that goes a long way to making things simpler for all
of the different arches
- tty documentation cleanups and movements to their own place in
the documentation tree
- old tty driver cleanups and fixes from Jiri to bring some
existing drivers into the modern world
- RS485 cleanups and unifications to make it easier for
individual drivers to support this mode instead of having to
duplicate logic in each driver
- Lots of 8250 driver updates and additions
- new device id additions
- n_gsm continued fixes and cleanups
- other minor serial driver updates and cleanups
All of these have been in linux-next for weeks with no reported issues.

Quite a large number of conversions this time around, courtesy of Uwe
who has been working tirelessly on these. No drivers of the legacy API
are left at this point, so as a next step the old API can be removed.
Support is added for a few new devices such as the Xilinx AXI timer-
based PWMs and the PWM IP found on Sunplus SoCs.
Other than that, there's a number of fixes, cleanups and optimizations.

Some (most?) drivers emit the inactive state when the PWM is disabled.
However there are exceptions, so document that a consumer better doesn't
depend on this behaviour.
Some known exceptions:
- imx27 emits 0 independent of the configured polarity
- mxs just drives the output to the last emitted state.
- iqs620a makes the output tristated on disable, so an external
pull-down would be required.

Extend the firmware subsystem to support a persistent sysfs interface that
userspace may use to initiate a firmware update. For example, FPGA based
PCIe cards load firmware and FPGA images from local FLASH when the card
boots. The images in FLASH may be updated with new images provided by the
user at his/her convenience.
A device driver may call firmware_upload_register() to expose persistent
"loading" and "data" sysfs files. These files are used in the same way as
the fallback sysfs "loading" and "data" files. When 0 is written to
"loading" to complete the write of firmware data, the data is transferred
to the lower-level driver using pre-registered call-back functions. The
data transfer is done in the context of a kernel worker thread.

The current documentation for the residue reported in a cyclic transfer
case mentions that the reported residue should be relative to the current
period only. However the definition of DMA_RESIDUE_GRANULARITY_SEGMENT
specifies that the residue should be updated after each period for
a cyclic transfer, which is in direct contradiction.
Moreover the pcm_dmaengine common code uses the residue relative to
the whole cyclic buffer size, not one period.
Correct the residue-related documentation to reflect this.

Improve ATA queued command allocation as follows:
- For attaining a qc tag for a SAS host we need to allocate a bit in
ata_port.sas_tag_allocated bitmap.
However we already have a unique tag per device in range
[0, ATA_MAX_QUEUE -1] in the scsi cmnd budget token, so just use that
instead.
- It is a bit pointless to have ata_qc_new_init() in libata-core.c since it
pokes scsi internals, so inline it in ata_scsi_qc_new() (in
libata-scsi.c). Also update Doc accordingly.
- Use standard SCSI helpers set_host_byte() and set_status_byte() in
ata_scsi_qc_new().
Christoph Hellwig originally contributed the change to inline
ata_qc_new_init().

Add a general purpose helper to deep dive into dma_fence_chain/dma_fence_array
structures and iterate over all the fences in them.
This is useful when we need to flatten out all fences in those structures.

Pull CXL (Compute Express Link) updates from Dan Williams:
"This development cycle extends the subsystem to discover CXL resources
throughout a CXL/PCIe switch topology and respond to hot add/remove
events anywhere in that topology.
This is more foundational infrastructure in preparation for dynamic
memory region provisioning support. Recall that CXL memory regions, as
the new "Theory of Operation" section of
Documentation/driver-api/cxl/memory-devices.rst describes, bring
storage volume striping semantics to memory.
The hot add/remove behavior is validated with extensions to the
cxl_test unit test environment and this test in the cxl-cli test
suite:
https://github.com/pmem/ndctl/blob/djbw/for-74/cxl/test/cxl-topology.sh

The overwhelming bulk of this pull request is a change from Uwe
Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus types,
causing updates to most SPI device drivers. The branch with that on has
been cross merged with a couple of other trees which added new SPI
drivers this cycle, I'm not expecting any build issues resulting from
the change.
Otherwise it's been a relatively quiet release with some new device
support, a few minor features and the welcome completion of the
conversion of the subsystem to use GPIO descriptors rather than numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO
descriptors rather than numbers.
- Quite a few DT schema conversions.
- Support for multiple SPI devices on a bus in ACPI systems.
- Big overhaul of the PXA2xx SPI driver.
- Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
Sunplus SP7021.

"The overwhelming bulk of this pull request is a change from Uwe
Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus
types, causing updates to most SPI device drivers. The branch with
that on has been cross merged with a couple of other trees which added
new SPI drivers this cycle, I'm not expecting any build issues
resulting from the change.
Otherwise it's been a relatively quiet release with some new device
support, a few minor features and the welcome completion of the
conversion of the subsystem to use GPIO descriptors rather than
numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO
descriptors rather than numbers.
- Quite a few DT schema conversions.
- Support for multiple SPI devices on a bus in ACPI systems.
- Big overhaul of the PXA2xx SPI driver.
- Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
Sunplus SP7021"
[ And this is obviously where that spi change that snuck into the
regulator tree _should_ have been :^]

Block Aperture Window support was an attempt to layer an error model
over PMEM for platforms that did not support machine-check-recovery.
However, it was abandoned before it ever shipped, and only ever existed
in the ACPI specification. Meanwhile Linux has carried a large pile of
dead code for non-shipping infrastructure. For years it has been off to
the side out of the way, but now CXL and recent directions with DAX
support have the potential to collide with this code.
In preparation for adding discontiguous namespace support, a
pre-requisite for the nvdimm subsystem to replace device-mapper for
striping + concatenation use cases, delete BLK aperture support.
On the obscure chance that some hardware vendor shipped support for this
mode, note that the driver will still keep BLK space reserved in the
label area. So an end user in this case would still have the opportunity
to report the regression to get BLK-mode support restored without
risking the data they have on that device.

At this point the subsystem can enumerate all CXL ports (CXL.mem decode
resources in upstream switch ports and host bridges) in a system. The
last mile is connecting those ports to endpoints.
The cxl_mem driver connects an endpoint device to the platform CXL.mem
protoctol decode-topology. At ->probe() time it walks its
device-topology-ancestry and adds a CXL Port object at every Upstream
Port hop until it gets to CXL root. The CXL root object is only present
after a platform firmware driver registers platform CXL resources. For
ACPI based platform this is managed by the ACPI0017 device and the
cxl_acpi driver.
The ports are registered such that disabling a given port automatically
unregisters all descendant ports, and the chain can only be registered
after the root is established.
Given ACPI device scanning may run asynchronously compared to PCI device
scanning the root driver is tasked with rescanning the bus after the
root successfully probes.
Conversely if any ports in a chain between the root and an endpoint
becomes disconnected it subsequently triggers the endpoint to
unregister. Given lock depenedencies the endpoint unregistration happens
in a workqueue asynchronously. If userspace cares about synchronizing
delayed work after port events the /sys/bus/cxl/flush attribute is
available for that purpose.

The need for a CXL port driver and a dedicated cxl_bus_type is driven by
a need to simultaneously support 2 independent physical memory decode
domains (cache coherent CXL.mem and uncached PCI.mmio) that also
intersect at a single PCIe device node. A CXL Port is a device that
advertises a CXL Component Register block with an "HDM Decoder
Capability Structure".
>From Documentation/driver-api/cxl/memory-devices.rst:
Similar to how a RAID driver takes disk objects and assembles them into
a new logical device, the CXL subsystem is tasked to take PCIe and ACPI
objects and assemble them into a CXL.mem decode topology. The need for
runtime configuration of the CXL.mem topology is also similar to RAID in
that different environments with the same hardware configuration may
decide to assemble the topology in contrasting ways. One may choose
performance (RAID0) striping memory across multiple Host Bridges and
endpoints while another may opt for fault tolerance and disable any
striping in the CXL.mem topology.
The port driver identifies whether an endpoint Memory Expander is
connected to a CXL topology. If an active (bound to the 'cxl_port'
driver) CXL Port is not found at every PCIe Switch Upstream port and an
active "root" CXL Port then the device is just a plain PCIe endpoint
only capable of participating in PCI.mmio and DMA cycles, not CXL.mem
coherent interleave sets.
The 'cxl_port' driver lets the CXL subsystem leverage driver-core
infrastructure for setup and teardown of register resources and
communicating device activation status to userspace. The cxl_bus_type
can rendezvous the async arrival of platform level CXL resources (via
the 'cxl_acpi' driver) with the asynchronous enumeration of Memory
Expander endpoints, while also implementing a hierarchical locking model
independent of the associated 'struct pci_dev' locking model. The
locking for dport and decoder enumeration is now handled in the core
rather than callers.
For now the port driver only enumerates and registers CXL resources
(downstream port metadata and decoder resources) later it will be used
to take action on its decoders in response to CXL.mem region
provisioning requests.
Note1: cxlpci.h has long depended on pci.h, but port.c was the first to
not include pci.h. Carry that dependency in cxlpci.h.
Note2: cxl port enumeration and probing complicates CXL subsystem init
to the point that it helps to have centralized debug logging of probe
events in cxl_bus_probe().

Rename struct dma_buf_map to struct iosys_map and corresponding APIs.
Over time dma-buf-map grew up to more functionality than the one used by
dma-buf: in fact it's just a shim layer to abstract system memory, that
can be accessed via regular load and store, from IO memory that needs to
be acessed via arch helpers.
The idea is to extend this API so it can fulfill other needs, internal
to a single driver. Example: in the i915 driver it's desired to share
the implementation for integrated graphics, which uses mostly system
memory, with discrete graphics, which may need to access IO memory.
The conversion was mostly done with the following semantic patch:
@r1@
@@
- struct dma_buf_map
+ struct iosys_map
@r2@

Then some files had their includes adjusted and some comments were
update to remove mentions to dma-buf-map.
Since this is not specific to dma-buf anymore, move the documentation to
the "Bus-Independent Device Accesses" section.
v2:
- Squash patches
v3:
- Fix wrong removal of dma-buf.h from MAINTAINERS
- Move documentation from dma-buf.rst to device-io.rst

The code and documentation are more difficult to maintain when kept
separately. This is further compounded when the standard structure
documentation infrastructure is not used.
Move the documentation into the code, use the standard documentation
infrastructure, add current documented functions, and reference the text

It was unclear when the auxiliary device objects were to be free'ed by
the parent (registering) driver.
Also there are some patterns like using devm_add_action_or_reset() which
are helpful to mention to those using the interface to ensure they don't
double free or miss freeing the auxiliary devices.

The documentation for creating an auxiliary device is a 3 step not a 2
step process. Specifically the requirements of setting the name, id,
dev.release, and dev.parent fields was not clear as a precursor to the '2
step' process documented.
Clarify by declaring this a 3 step process starting with setting the
fields of struct auxiliary_device correctly.
Also add some sample code and tie the change into the rest of the
documentation.

The FPGA region class driver data structure is being treated as a
managed resource instead of using the standard dev_release call-back
function to release the class data structure. This change removes the
managed resource code and combines the create() and register()
functions into a single register() or register_full() function.
The register_full() function accepts an info data structure to provide
flexibility in passing optional parameters. The register() function
supports the current parameter list for users that don't require the
use of optional parameters.

Currently it can difficult to determine what dmatest does without

The description is taken mostly from the patch header of
commit 4a776f0aa9 ("dmatest: Simple DMA memcpy test client").
It has been edited and updated slightly. Nevertheless the new text was
largely written by Haarvard Skinnemoen and was copied from another

Counter subsystem changes now sent separately.
This has been a busy cycle, so lots here and a few more stragglers to
come next week.
Big new feature in this cycle is probably output buffer support.
This has been in the works for a very long time so it's great to see
Mihail pick up the challenge and build upon his predecessors work to finally
bring this feature to mainline.
New device support
------------------
* adi,adxl313
- New driver and dt bindings for this low power accelerometer.
* adi,adxl355
- New driver and dt bindings for this accelerometer.
- Later series adds buffer support.
* asahi-kasei,ak8975
- Minor additions to driver to support ak09916
* aspeed,aspeed-adc
- Substantial rework plus feature additions to add support for the
ast2600 including a new dt bindings doc.
* atmel,at91_sama5d2
- Rework and support introduced for the sama7g5 parts.
* maxim,max31865
- New driver and bindings for this RTD temperature sensor chip.
* nxp,imx8qxp
- New driver and bindings for the ADC found on the i.MX 8QuadXPlus Soc.
* senseair,sunrise
- New driver and bindings for this family of carbon dioxide gas sensors.
* sensiron,scd4x
- New driver and bindings for this carbon dioxide gas sensor.
New features
------------
* Output buffer support. Works in a similar fashion to input buffers, but
in this case userspace pushes data into the kfifo which is then drained
to the device when a trigger occurs. Support added to the ad5766 DAC
driver.
* Core, devm_iio_map_array_register() to avoid need for
devm_add_action_or_reset() based cleanup in fully managed allocation
drivers.
* Core iio_push_to_buffers_with_ts_unaligned() function to safely handle a
few drivers where it really hard to ensure the correct data alignment in
an iio_push_to_buffers_with_timestamp() call. Note this uses a bounce
buffer so should be avoided whenever possible. Used in the ti,adc108s102,
invense,mpu3050 and adi,adis16400. This closes the last known set
of drivers with alignment issues at this interface.
* maxim,max1027
- Substantial rework to this driver main target of which was supporting
use of other triggers than it's own EOC interrupt.
- Transfer optimization.
* nxp,fxls8962af
- Threshold even support including using it as a wakeup source.
Cleanups, minor fixes etc
-------------------------
Chances of a common type to multiple drivers:
* devm_ conversion and drop of .remove() callbacks in:
- adi,ad5064
- adi,ad7291
- adi,ad7303
- adi,ad7746
- adi,ad9832
- adi,adis16080
- dialog,da9150-gpadc
- intel,mrfld_adc
- marvell,berlin2
- maxim,max1363
- maxim,max44000
- nuvoton,nau7802
- st_sensors (includes a lot of rework!)
- ti,ads8344
- ti,lp8788
* devm_platform_ioremap_resource() used to reduce boilerplate
- cirrus,ep93xx
- rockchip,saradc
- stm,stm32-dac
* Use dev_err_probe() in more places to both not print on deferred probe and
ensure a reason for the deferral is available for debug purposes.
- adi,ad8801
- capella,cm36651
- linear,ltc1660
- maxim,ds4424
- maxim,max5821
- microchip,mcp4922
- nxp,lpc18xx
- onnn,noa1305
- st,lsm9ds0
- st,st_sensors
- st,stm32-dac
- ti,afe4403
- ti,afe4404
- ti,dac7311
* Drop error returns in SPI and I2C remove() functions as they are ignored and
long term plan is to change these all over to returning void. In some cases
these patches just make it 'obvious' they always return 0 where it was the
case before but not easy to tell.
- adi,ad5380
- adi,ad5446
- adi,ad5686
- adi,ad5592r
- bosch,bma400
- bosch,bmc150
- fsl,mma7455

- kionix,kxsd9
- maxim,max5487
- meas,ms5611
- ti,afe4403
Driver specific changes
* adi,ad5770r
- Bring driver inline with documented bindings.
* adi,ad7746
- Trivial style fix
* adi,ad7949
- Express some magic values as the underlying parts via new #defines.
- Make it work with SPI controllers that don't support 14 or 16 bit messages
- Support selection of voltage reference from dt including expanding the
dt-bindings to cover this new functionality.
* adi,ad799x
- Implement selection of external reference voltage on AD7991, AD7995 and
AD7999.
- Add missing dt-bindings doc for devices supported by this driver.
* adi,adislib
- Move interrupt startup to better location in startup flow.
- Handle devices that cannot mask/unmask the drdy pin and must instead mask
at the interrupt controller. Applies to the adis16460 and adis16475 from
which we then drop equivalent code.
* adi,ltc2983
- Add support for optional reset pin.
- Fail to probe if no channels specified in dt binding.
* asahi-kasei,ak8975
- dt-binding additions of missing vid-supply regulator.
* aspeed,aspeed-adc

First set of IIO new device and feature support for the 5.16 cycle
Counter subsystem changes now sent separately.
This has been a busy cycle, so lots here and a few more stragglers to
come next week.
Big new feature in this cycle is probably output buffer support.
This has been in the works for a very long time so it's great to see
Mihail pick up the challenge and build upon his predecessors work to finally
bring this feature to mainline.
New device support
------------------
* adi,adxl313
- New driver and dt bindings for this low power accelerometer.
* adi,adxl355
- New driver and dt bindings for this accelerometer.
- Later series adds buffer support.
* asahi-kasei,ak8975
- Minor additions to driver to support ak09916
* aspeed,aspeed-adc
- Substantial rework plus feature additions to add support for the
ast2600 including a new dt bindings doc.
* atmel,at91_sama5d2
- Rework and support introduced for the sama7g5 parts.
* maxim,max31865
- New driver and bindings for this RTD temperature sensor chip.
* nxp,imx8qxp
- New driver and bindings for the ADC found on the i.MX 8QuadXPlus Soc.
* senseair,sunrise
- New driver and bindings for this family of carbon dioxide gas sensors.
* sensiron,scd4x
- New driver and bindings for this carbon dioxide gas sensor.
New features
------------
* Output buffer support. Works in a similar fashion to input buffers, but
in this case userspace pushes data into the kfifo which is then drained
to the device when a trigger occurs. Support added to the ad5766 DAC
driver.
* Core, devm_iio_map_array_register() to avoid need for
devm_add_action_or_reset() based cleanup in fully managed allocation
drivers.
* Core iio_push_to_buffers_with_ts_unaligned() function to safely handle a
few drivers where it really hard to ensure the correct data alignment in
an iio_push_to_buffers_with_timestamp() call. Note this uses a bounce
buffer so should be avoided whenever possible. Used in the ti,adc108s102,
invense,mpu3050 and adi,adis16400. This closes the last known set
of drivers with alignment issues at this interface.
* maxim,max1027
- Substantial rework to this driver main target of which was supporting
use of other triggers than it's own EOC interrupt.
- Transfer optimization.
* nxp,fxls8962af
- Threshold even support including using it as a wakeup source.
Cleanups, minor fixes etc
-------------------------
Chances of a common type to multiple drivers:
* devm_ conversion and drop of .remove() callbacks in:
- adi,ad5064
- adi,ad7291
- adi,ad7303
- adi,ad7746
- adi,ad9832
- adi,adis16080
- dialog,da9150-gpadc
- intel,mrfld_adc
- marvell,berlin2
- maxim,max1363
- maxim,max44000
- nuvoton,nau7802
- st_sensors (includes a lot of rework!)
- ti,ads8344
- ti,lp8788
* devm_platform_ioremap_resource() used to reduce boilerplate
- cirrus,ep93xx
- rockchip,saradc
- stm,stm32-dac
* Use dev_err_probe() in more places to both not print on deferred probe and
ensure a reason for the deferral is available for debug purposes.
- adi,ad8801
- capella,cm36651
- linear,ltc1660
- maxim,ds4424
- maxim,max5821
- microchip,mcp4922
- nxp,lpc18xx
- onnn,noa1305
- st,lsm9ds0
- st,st_sensors
- st,stm32-dac
- ti,afe4403
- ti,afe4404
- ti,dac7311
* Drop error returns in SPI and I2C remove() functions as they are ignored and
long term plan is to change these all over to returning void. In some cases
these patches just make it 'obvious' they always return 0 where it was the
case before but not easy to tell.

Driver specific changes
* adi,ad5770r
- Bring driver inline with documented bindings.
* adi,ad7746
- Trivial style fix
* adi,ad7949
- Express some magic values as the underlying parts via new #defines.
- Make it work with SPI controllers that don't support 14 or 16 bit messages
- Support selection of voltage reference from dt including expanding the
dt-bindings to cover this new functionality.
* adi,ad799x
- Implement selection of external reference voltage on AD7991, AD7995 and
AD7999.
- Add missing dt-bindings doc for devices supported by this driver.
* adi,adislib
- Move interrupt startup to better location in startup flow.
- Handle devices that cannot mask/unmask the drdy pin and must instead mask
at the interrupt controller. Applies to the adis16460 and adis16475 from
which we then drop equivalent code.
* adi,ltc2983
- Add support for optional reset pin.
- Fail to probe if no channels specified in dt binding.
* asahi-kasei,ak8975
- dt-binding additions of missing vid-supply regulator.

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.

Now that the internals of mailbox operations are abstracted from the PCI
specifics a bulk of infrastructure can move to the core.
The CXL_PMEM driver intends to proxy LIBNVDIMM UAPI and driver requests
to the equivalent functionality provided by the CXL hardware mailbox
interface. In support of that intent move the mailbox implementation to
a shared location for the CXL_PCI driver native IOCTL path and CXL_PMEM
nvdimm command proxy path to share.
A unit test framework seeks to implement a unit test backend transport
for mailbox commands to communicate mocked up payloads. It can reuse all
of the mailbox infrastructure minus the PCI specifics, so that also gets
moved to the core.
Finally with the mailbox infrastructure and ioctl handling being
transport generic there is no longer any need to pass file
file_operations to devm_cxl_add_memdev(). That allows all the ioctl
boilerplate to move into the core for unit test reuse.
No functional change intended, just code movement.

Pull drm updates from Dave Airlie:
"Highlights:
- i915 has seen a lot of refactoring and uAPI cleanups due to a
change in the upstream direction going forward
This has all been audited with known userspace, but there may be
some pitfalls that were missed.
- i915 now uses common TTM to enable discrete memory on DG1/2 GPUs
- i915 enables Jasper and Elkhart Lake by default and has preliminary
XeHP/DG2 support
- amdgpu adds support for Cyan Skillfish
- lots of implicit fencing rules documented and fixed up in drivers
- msm now uses the core scheduler
- the irq midlayer has been removed for non-legacy drivers
- the sysfb code now works on more than x86.
Otherwise the usual smattering of stuff everywhere, panels, bridges,
refactorings.
Detailed summary:
core:
- extract i915 eDP backlight into core

Lightnvm supports the OCSSD 1.x and 2.0 specs which were early attempts
to produce Open Channel SSDs and never made it into the NVMe spec
proper. They have since been superceeded by NVMe enhancements such
as ZNS support. Remove the support per the deprecation schedule.

This pairs with vfio_init_group_dev() and allows undoing any state that is
stored in the vfio_device unrelated to registration. Add appropriately
placed calls to all the drivers.
The following patch will use this to add pre-registration state for the
device set.
