The hardware timestamp engine documentation is driver API material, and
really belongs in the driver-API book; move it there.

Pull driver core updates from Greg KH:
"Here is the set of driver core changes for 5.19-rc1.
Lots of tiny driver core changes and cleanups happened this cycle, but
the two major things are:
- 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 include:
- 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.
All have been tested in linux-next for weeks, with no reported issues
other than the above-mentioned boot time-outs"

Pull tty and serial driver updates from Greg KH:
"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

Pull pwm updates from Thierry Reding:
"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.

based PWMs and the PWM IP found on Sunplus SoCs.
Other than that, there's a number of fixes, cleanups and optimizations"

Pull interrupt handling updates from Thomas Gleixner:
"Core code:
- Make the managed interrupts more robust by shutting them down in
the core code when the assigned affinity mask does not contain
online CPUs.
- Make the irq simulator chip work on RT
- A small set of cpumask and power manageent cleanups
Drivers:
- A set of changes which mark GPIO interrupt chips immutable to
prevent the GPIO subsystem from modifying it under the hood. This
provides the necessary infrastructure and converts a set of GPIO
and pinctrl drivers over.
- A set of changes to make the pseudo-NMI handling for GICv3 more
robust: a missing barrier and consistent handling of the priority
mask.
- Another set of GICv3 improvements and fixes, but nothing
outstanding
- The usual set of improvements and cleanups all over the place
- No new irqchip drivers and not even a new device tree binding!

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.

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().

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
Summary:
- Add a driver for 'struct cxl_memdev' objects responsible for
CXL.mem operation as distinct from 'cxl_pci' mailbox operations.
Its primary responsibility is enumerating an endpoint 'struct
cxl_port' and all the 'struct cxl_port' instances between an
endpoint and the CXL platform root.
- Add a driver for 'struct cxl_port' objects responsible for
enumerating and operating all Host-managed Device Memory (HDM)
decoder resources between the platform-level CXL memory
description, all intervening host bridges / switches, and the HDM
resources in endpoints.
- Update the cxl_pci driver to validate CXL.mem operation precursors
to HDM decoder operation like ready-polling, and legacy CXL 1.1
DVSEC based CXL.mem configuration.
- Add basic lockdep coverage for usage of device_lock() on CXL
subsystem objects similar to what exists for LIBNVDIMM. Include a
compile-time switch for which subsystem to validate at run-time.
- Update cxl_test to emulate a one level switch topology.
- Document a "Theory of Operation" for the subsystem.
- Add 'numa_node' and 'serial' attributes to cxl_memdev sysfs
- Include miscellaneous fixes for spec / QEMU CXL emulation
compatibility and static analysis reports"

Pull spi updates from Mark Brown:
"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 :^]
