Add a driver for the Sensirion SLF3S family of digital
liquid-flow sensors on I2C. Currently supported variants are
SLF3S-0600F, SLF3S-1300F and SLF3S-4000B; they share the same
register map and differ only in flow-scale factor and calibrated
measurement range. The variant (and therefore the scale) is
auto-detected from the product-information register at probe time;
a sensor reporting an unknown sub-type falls back to the variant
named in the device tree / I2C table, so a drop-in replacement part
keeps working on a kernel that does not know its sub-type yet.
Each measurement frame returns a 16-bit signed flow value, a
16-bit signed temperature reading and a status word, each
protected by a CRC-8 byte. The driver exposes the flow rate as
IIO_VOLUMEFLOW and the temperature as IIO_TEMP via the standard
IIO read_raw / read_scale interface.
The volume-flow scale is reported in m^3/s. As the per-LSB scale
is on the order of 1e-12 m^3/s, it is emitted as a 64-bit
fixed-point value with femto (1e-15) resolution
(IIO_VAL_DECIMAL64_FEMTO) so the small SI value keeps full
precision. This relies on the IIO_VAL_DECIMAL64_FEMTO format type
added earlier in this series.
The active calibration medium can be switched at runtime between
the factory-calibrated water and isopropyl-alcohol modes via the
in_volumeflow_medium sysfs attribute; the sensor starts in water
mode after probe.
The sensor has no low-power state of its own, so system suspend
stops the measurement and disables the vdd supply; resume powers
the sensor back up, waits out the power-up time and restarts the
measurement with the previously active medium, following the
scd30/scd4x precedent.
This driver also creates the drivers/iio/flow/ subdirectory and
the corresponding Kconfig/Makefile glue.

Document the bindings for the Sensirion SLF3S family of digital
liquid-flow sensors on I2C. The family currently covers the
SLF3S-0600F, SLF3S-1300F and SLF3S-4000B variants.
All variants share the same register map and differ only in the flow
scale factor and the calibrated measurement range, which the driver
reads back from the product-information register. Since that lookup
is needed in any case, a fallback compatible would buy nothing, so
each variant gets its own compatible without a fallback. A future
drop-in compatible part can then claim one of these compatibles and
work on kernels that do not know its product ID yet.
The active calibration medium (water / IPA) is runtime-switchable
via the in_volumeflow_medium sysfs attribute and therefore not a
DT property.

Add a new IIO channel type for liquid volumetric flow sensors. The
unit exposed via the standard _scale attribute is cubic metres per
second (m^3/s), following the SI convention used by the other IIO
channel types.
Update iio-core's name table, the iio_event_monitor whitelist and
the sysfs-bus-iio ABI document to match. The new _scale attribute is
folded into the existing shared _scale block; only the per-type _raw
needs a fresh entry.

Add AudioReach support for LPASS Audio IF based TDM backends and wire it
up for the sc8280xp machine driver.
The series first adds topology-driven Audio IF source/sink handling so
the DSP interface parameters can be described by topology while runtime
media format and slot configuration still come from the machine driver.
It then adds TDM DAI operations for q6apm-lpass-dais, exposes the Audio
IF clock IDs through the q6dsp-lpass-ports binding and q6prm clock
tables, and introduces common QCOM helpers for parsing standard
dai-tdm-slot-* properties from backend CPU and codec endpoints.
Finally, sc8280xp uses the common helpers during hw_params to program
CPU and codec TDM slots, derive the backend bit clock from the active
PCM parameters, and request the CPU and codec clocks before the stream is
started.

Allow standard dai-tdm-slot-* properties in the CPU and codec child
nodes of a DAI link.
The QCOM machine driver parses these child nodes to configure TDM slots
on the active CPU and codec DAIs. The properties are already defined by
the common tdm-slot binding, but qcom,sm8250.yaml currently rejects them
because the CPU and codec child nodes set additionalProperties: false.
Permit dai-tdm-slot-num, dai-tdm-slot-width and dai-tdm-slot-[rt]x-mask
there so boards using TDM backends can describe the slot layout without
schema warnings.

The security team is still seeing a lot of reports lacking a full patch
and showing missing contents and formatting issues. Since AI assistants
tend to be better than humans at following instructions, let's defer to
coding-assistants.rst to follow mandatory steps, and insist on the plain
text format, as well as asking for recipient addresses and an e-mail
client setup hint to be mentioned early in the report for the reporter.
Also add a link to https://github.com/masoncl/kres.git which contains
way more advanced and detailed steps for those willing to go further.
Tested with Opus-5 and Qwen3.6-27B-Architect-Polaris2-Fable-B-F451, both
of which proceeded according to instructions.

Due to the increasing capabilities of available AI models, it's becoming
common to see them used to find bugs anywhere. Unfortunately the quality
of reports (especially when they're believed to be security relevant) is
still lacking a lot.
Let's add a section dedicated to bug finding, explaining the few
mandatory steps (noting commit ID, writing the fix from the session that
found the bug, building and testing, etc). This was tested both against
Qwen3.6-27B-Architect-Polaris2-Fable-B-F451 running under Hermes, and
Opus-5, and both followed the instructions to the letter, verifying
their results and checking threat-model.rst to decline the vulnerability
aspect. At least in the current form it's expected to improve the
situation a little bit.

When originally writing the "fake USB device" entry, it was difficult
to find a suitable section for it and it ended up in "non production
use" but that doesn't fit particularly well. Actually it's very similar
to crafted filesystems, it's a matter of spec violation. Both drivers
and FS are written against a spec, and what the threat model doesn't
cover is out-of-spec use. So let's move the entry there and rename the
crafted FS entry to "Non-conforming devices and media" instead.
Overall it looks more consistent.
The spec was tested agains Qwen3.6-27B-Architect-Polaris2-Fable-B-F451,
Opus-5 and Gemini by reading the threat-model file, then reading a tens
of FS and driver fixes, and they were now all properly classified as
regular bugs, except two that Gemini and Opus rightfully classified as
vulns (Qwen didn't spot the security potential but that's out of our
scope).

Throwing an LLM (Opus 5) at a file looking for random bugs after having
read the threat model made it ignore certain bugs it found because "the
threat model said they must be ignored". When asked why, the LLM
rightfully reported the ambiguous wording used at a few places:
"is not a security bug", which can also be read as "is not a bug",
despite the rest of the document. That is particularly true when the
LLM decides to look for info using grep.
This change replaces "security bug" with "vulnerability" at a few places
in order to remove this identified ambiguity, and uses "bugs" instead of
issues in two such sentences to insist that what is described remains a
bug.

The size of a sequential zone backing file records the amount of data
written and is used to restore the zone state. A backing file whose size
is equal to the zone capacity is restored as a full zone, while a file
larger than the zone capacity is rejected as invalid.
However, zloop_finish_zone() currently truncates the backing file to the
zone size. For devices with a reduced zone capacity, finishing a zone
therefore creates a backing file larger than the zone capacity. After the
device is removed and later re-added, that zone file is rejected instead
of being restored as a full zone.
Truncate finished sequential zones to the zone capacity, matching the
persistent representation accepted by zloop_update_seq_zone() for a full
zone.

So far, parts that could only do differential voltage measurements were
only required to have a consistent labeling of their channels by complying
either to voltageY or to voltageY-voltageZ ABI. Over time, code maintainers
came to the conclusion that the voltageY-voltageZ ABI is better suited for
differential-only chips as it provides a simple indication to users that
the channels measure the difference of two inputs.
Adjust the ABI documentation to recommend using the voltageY-voltageZ ABI
for chips that do only differential voltage measurements.

Add the ICM42607 and ICM42607P inertial measurement unit.
This device is functionally very similar to the icm42600 series with a
very different register layout. The icm42607 currently does not use an
interrupt because wake on movement and buffers are not supported, and
cannot be implemented on my test device which lacks an interrupt line.

The requirement to identify specific models used in the Assisted-by tag
provides free advertising to proprietary software companies while adding
little or no useful information. Change the requirement to simply:
Assisted-by: LLM
to capture the fact that an LLM was used without tracking which one.

Describe the interpreters a 'B' entry can bind while it is disabled, what
binding a file buys over naming a path the exec resolves, how a load
program picks one, that an entry binds at most 100 interpreters, and
that enabling the entry seals the set.

Describe the 'D' flag and what it changes about a registration:
- that the entry has to be enabled before it dispatches anything
- and that the flag is not read back
Scope the bpf section's "carries no flags" rule to invocation flags now
that 'D' composes with 'B'.
