Add bindings for STM32 Octo Memory Manager (OMM) controller.
OMM manages:
- the muxing between 2 OSPI busses and 2 output ports.
There are 4 possible muxing configurations:
- direct mode (no multiplexing): OSPI1 output is on port 1 and OSPI2
output is on port 2
- OSPI1 and OSPI2 are multiplexed over the same output port 1
- swapped mode (no multiplexing), OSPI1 output is on port 2,
OSPI2 output is on port 1
- OSPI1 and OSPI2 are multiplexed over the same output port 2
- the split of the memory area shared between the 2 OSPI instances.
- chip select selection override.
- the time between 2 transactions in multiplexed mode.

This patch replaces the TODO for DMA_ASYNC_TX in the DMA engine
provider documentation. The flag is automatically set by the DMA
framework when a device supports key asynchronous memory-to-memory
operations such as memcpy, memset, xor, pq, xor_val, and pq_val.
It must not be set by drivers directly.

Commit 6c2f0b28d76e ("docs: Makefile: store __pycache__ at the output
directory") assigns a new path to PYTHONPYCACHEPREFIX for building
kernel documentation.
However, it is not necessarily optimal for everyone.
If you find PYTHONPYCACHEPREFIX is already set, it strongly suggests
that the developer has selected the setting as best suited for one's own
workflow.
Use "?=" in the assignment to PYTHONPYCACHEPREFIX so that the path of
$(abspath $(BUILDDIR)/__pycache__) works only as a safeguard.

Much like device numbers that used to be assigned by LANANA (see commit
ebdf4040c16df5 ("Documentation: update the devices.txt documentation"),
ioctl numbers list is maintained by general kernel community nowadays
instead of contacting Michael directly as he's long stepped down from
kernel-related activity (his last LKML message was from 2003 [1] and
he's in CREDITS since the beginning of kernel's git history). Also,
patch (including one to update ioctl numbers list) submission now
follows process as described in
Documentation/process/submitting-patches.rst rather than sending
patches directly to Linus as in the distant past.
Update the docs to reflect that.

Devlink param and health reporter fmsg use attributes with dynamic type
which is determined according to a different type. Currently used values
are NLA_*. The problem is, they are not part of UAPI. They may change
which would cause a break.
To make this future safe, introduce a enum that shadows NLA_* values in
it and is part of UAPI.
Also, this allows to possibly carry types that are unrelated to NLA_*
values.

In Xiaomi Poco F1 (qcom/sdm845-xiaomi-beryllium-ebbg.dts), the FocalTech
FT8719 touchscreen is integrally connected to the display panel
(EBBG FT8719) and thus should be power sequenced together with display
panel using the panel property. Since the edt-ft5x06 touchscreen binding
uses almost all the properties present in touchscreen.yaml, let's remove
additionalProperties: false and use unevaluatedProperties to include all
the properties, including the needed panel property.

Since commit 98e0500eadb7 ("media: i2c: imx290: Add configurable link

link-frequency settings 2-lane (445500000, 297000000) and 4-lane

these exact settings.

users to incorporate this sensor in their device tree descriptions
without having to read the driver sources when the driver fails to

Device Tree and Ethernet MAC driver writers often misunderstand RGMII
delays. Rewrite the Normative section in terms of the PCB, is the PCB
adding the 2ns delay. This meaning was previous implied by the
definition, but often wrongly interpreted due to the ambiguous wording
and looking at the definition from the wrong perspective. The new
definition concentrates clearly on the hardware, and should be less
ambiguous.
Add an Informative section to the end of the binding describing in
detail what the four RGMII delays mean. This expands on just the PCB
meaning, adding in the implications for the MAC and PHY.
Additionally, when the MAC or PHY needs to add a delay, which is
software configuration, describe how Linux does this, in the hope of
reducing errors. Make it clear other users of device tree binding may
implement the software configuration in other ways while still
conforming to the binding.

Merge series from Philipp Stanner <phasta@kernel.org>:
A year ago we spent quite some work trying to get PCI into better shape.
Some pci_ functions can be sometimes managed with devres, which is
obviously bad. We want to provide an obvious API, where pci_ functions
are never, and pcim_ functions are always managed.
Thus, everyone enabling his device with pcim_enable_device() must be
ported to pcim_ functions. Porting all users will later enable us to
significantly simplify parts of the PCI subsystem. See here [1] for
details.
This patch series does that for sound.
Feel free to squash the commits as you see fit.

Currently userspace software systemd treats `brightness` and
`actual_brightness` identically due to a bug found in an out of tree
driver.
This however causes problems for in-tree drivers that use brightness
to report user requested `brightness` and `actual_brightness` to report
what the hardware actually has programmed.
Clarify the documentation to match the behavior described in commit
6ca017658b1f9 ("[PATCH] backlight: Backlight Class Improvements").

Currently the calling conventions for ->d_automount() instances have
an odd wart - returned new mount to be attached is expected to have
refcount 2.
That kludge is intended to make sure that mark_mounts_for_expiry() called
before we get around to attaching that new mount to the tree won't decide
to take it out. finish_automount() drops the extra reference after it's
done with attaching mount to the tree - or drops the reference twice in
case of error. ->d_automount() instances have rather counterintuitive
boilerplate in them.
There's a much simpler approach: have mark_mounts_for_expiry() skip the
mounts that are yet to be mounted. And to hell with grabbing/dropping
those extra references. Makes for simpler correctness analysis, at that...

The following register contains bits that indicate the cause for the
previous reset.
PMx000000C0 (FCH::PM::S5_RESET_STATUS)
This is useful for debug. The reasons for reset are broken into 6 high level
categories. Decode it by category and print during boot.
Specifics within a category are split off into debugging documentation.
The register is accessed indirectly through a "PM" port in the FCH. Use
MMIO access in order to avoid restrictions with legacy port access.
Use a late_initcall() to ensure that MMIO has been set up before trying to
access the register.
This register was introduced with AMD Family 17h, so avoid access on older
families. There is no CPUID feature bit for this register.

The SG2044 shares the same reset controller as SG2042, so it
is just enough to use the compatible string of SG2042 as a
basis.
Add compatible string for the reset controller of SG2044.

The RK3576 SoC contains another standalone TRNG implementation. While
the register map and hardware is different, it has the same
clocks/interrupts/resets as the RK3588's TRNG, so can go in the same
binding.
Add the compatible and generalise the title/description of the binding
some more.

All legacy network transports have been removed. Vector transports
provide the same capabilities with significantly higher network
throughput. There is no reason to keep the legacy network transport
infrastructure anymore. Remove it to reduce the maintenance burden.

These legacy network transports were marked as obsolete in commit
40814b98a570 ("um: Mark non-vector net transports as obsolete").
More than five years have passed since then. Remove these network
transports to reduce the maintenance burden.
