The LM75 alert pin is asserted based on the value of alert polarity bit
of the configuration register. The device/driver default is 0 which means
alert pin is configured to be active-low. A value of 1 maps to inverted
(active-high).
Add an optional boolean property "ti,alert-polarity-active-high" to
override the alert pin polarity. When absent, the default active-low
polarity is kept.

The EMC2305 fan controller supports multiple independent PWM fan
outputs. Some systems require fans to enter a defined safe state
during system shutdown or reboot handoff, until firmware or the next
boot stage reconfigures the controller.
Add an optional "fan-shutdown-percent" property to fan child nodes
allowing the PWM duty cycle applied during shutdown to be configured
per fan output.

aspeed: First batch of ARM devicetree changes for v7.2
New platforms:
- Rainiera6 (Meta)
- SanMiguel (Meta)
Updated platforms:
- Anacapa: SGPIO line names and interrupt configuration
- Clemente: Remove TMP421 nodes
- Kommando: Enable networking via MAC2/MDIO2
- SanMiguel: Line names and interrupt configuration
AST2600 SoC updates:
- Describe PWM/Tach
- Describe I3C controllers
- Reorganise I2C nodes
Other notes:
91b9aed7381c ("ARM: dts: aspeed-g6: Add nodes for i3c controllers") currently
causes a new warning:
... /ahb/apb/bus@1e7a0000/syscon@0: failed to match any schema with compatible: ['aspeed,ast2600-i3c-global', 'syscon']
The patch necessary to address it has an R-b tag from Kryzsztof[2] but as best
I can tell is yet to be applied to the MFD tree. I've left the change in for now
as the warning will resolve once the binding patch is applied.
Lastly, as part of improving support for the Kommando card Anirudh has also
addressed[1] the persistent pain we've had with the phy-mode property for the
AST2600 MACs. Thanks to Andrew Lunn for being on the case for a while now, and
for those who tested Anirudh's patch.

RISC-V Devicetrees for v7.2
Sophgo:
For CV18xx serials:
- Add bindings for Milk-V "Duo S" board.
For SG2042:
- The CPU unit address incorrectly used decimal numbers,
especially for those nodes which value >= 10. Now
corrected to use hexadecimal.
- The MSI controller actually only supports 16 interrupts;
corrected to match the actual situation.
- PCIe RCs are cache-coherent with the CPU. Marked it out
for RC nodes.
For SG2044:
- The same as SG2042, use hex for CPU unit address.
In additional, update Chen Wang's email address for Sopgho

Tenstorrent device tree for v7.2
Add a riscv,pmu node to the Tenstorrent Blackhole SoC device tree. This
enables OpenSBI to expose the SBI PMU extension, allowing Linux perf to
use the 4 programmable counters (mhpmcounter3-6) across 3 event classes:
instruction commit, microarchitectural, and memory system events.
Extend the RISC-V IOMMU device tree bindings to document the Tenstorrent
IOMMU used in the Tenstorrent Atlantis SoC. A second register range is
added which contains M-mode only registers like PMAs and PMPs. The
binding will be used by OpenSBI and potentially other M-mode software.

Allwinner driver changes for 7.2
Mostly changes to the SRAM driver to allow for one SRAM region to be
"claimed" by multiple changes. When a region is "claimed" it is removed
or disconnected from the CPU's view. This is needed on the H6 and H616,
which have one alias region seemingly shared between the video codec
engine and the display engine.
One minor fix for the RSB driver is also included.

git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next
Pablo Neira Ayuso says:
====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for net-next,
this contains updates to address sashiko reports in IPVS and Netfilter
on possible pre-existing issues. This also includes a series to add
refcount for ct helper and timeout to deal with a corner case scenario
with unconfirmed conntracks flying to nfqueue.
1) Add a conn_max sysctl to IPVS to limit the maximum number of
connections, from Julian Anastasov.
2) Use get_unaligned_be16() to access TCP MSS in nfnetlink_osf,
from Fernando Fernandez Mancera.
3) Use {READ,WRITE}_ONCE to access helper flags from nfnetlink_helper.
Several patches for the synproxy infrastructure, from Fernando
Fernandez Mancera:
4) Drop packet if TCP timestamp adjustment fails.
5) Continue parsing of TCP timestamp to deal with possible duplicates.
6) Use {get,put}_unaligned_be32() to acess the TCP timestamp.
7) Hold ct->lock to initialize nf_ct_seqadj_init().
Updates for the ct timeout infrastructure, to deal with a corner case
for unconfirmed conntracks flying to nfqueue:
8) Add a refcount to track ct timeout policy use by ct extension,
release the timeout until the last ct extension drops the refcnt
on it.
Similar update for the ct helper infrastructure:
9) Dynamic allocation of ct helpers, as a preparation for adding
refcount to track ct extension use.
10) Move destroy_sibling_or_exp() to nf_conntrack_proto_gre, so
pptp conntrack helper module removal does not make this code
unreachable via the helper->destroy callback. This is another
dependency for the new refcount coming in this series.
11) Add a refcount to track use of it from the ct extension, then
ct helper and timeout is reachable to the connection until
it goes away.
12) Remove the genid infrastructure in ct extensions. The primary
goal was to detect that a ct extension such as ct timeout and
ct helper went stale for unconfirmed conntrack, either because
object or module was removed. This deactivates all ct extensions
though for this unconfirmed conntrack.
13) Call nf_ct_gre_keymap_destroy() if this is a master conntrack
with a pptp helper only.
sashiko.dev reports one more relevant issue when unsetting the helper
via ctnetlink that I will address in a follow up patch.
Then, two more assorted updates:
14) Avoid a unlikely underflow in bridge VLAN untag, only possible
if buggy bridge VLAN filtering is buggy, remove WARN_ON_ONCE
while at it. From David Carlier.
15) Use get_unaligned_be32() in nf_conntrack_tcp to access sack
extension, from Rosen Penev.

Pass KBUILD_MODNAME through the driver registration macro so that the
driver core can create the module symlink in sysfs for built-in drivers,
and fixup all callers.
The Rust platform adapter is updated to pass the module name through to
the new parameter.
Tested on qemu with:
- x86 defconfig + CONFIG_RUST
- arm64 defconfig + CONFIG_RUST + CONFIG_CORESIGHT stuff
Examples after this patch:

IIO: New device support, features and cleanup for the 7.2 cycle.
Like many areas of the kernel IIO has seen a lot of new contributors
though in this case that is not all AI driven, but also reflects and annual
surge of student contributions from usp.br. We also have several new
regular reviewers who are helping with the surge (thanks to all our
active reviewers!)
Given there was a lot of cases of similar improvements applied to
different drivers, I have grouped those into a special section (various
drivers) to avoid mass duplication.
New device support
------------------
adi,ad4130
- Add support for AD4129-4, AD4129-8, AD4130-4, AD4131-4 and AD4131-8
after reworking the driver to be suitable for multiple device support.
adi,ad4080
- Support the AD4880 and AD4884 dual-channel parts. Interesting parts
as have two separate data pipelines (including SPI buses interfaces),
but the only current backend IP combines the two so they cannot be
treated as independent devices.
adi,ad5706r
- New driver for this 4 channel current output DAC.
adi,ad4691
- New driver supporting this family of ADCs. Support for AD4691, AD4692,
AD4693 and AD4694 which support either 8 or 16 channels with different
max sampling rates. Feature rich driver including SPI offload support.
adi,ltc2983
- Add support for the ADT7604 in which the same sensor die as the
LTC2984 is used for leak detection (liquid coverage of a sense area).
allwinner,adc
- Support for A523 SoCs. Similar to existing parts but with an additional
clock. Includes adding support for non contiguous channel lookup
for in kernel use (fwnode_xlate callback).
broadcomm,apds9999
- New driver for the APDS9999 Ambient Light, RGB and proximity sensor.
memsic,mmc5983
- New driver for this 3-axis magnetometer.
taos,tsl2772
- Add support for the AVAGO APDS9900 and APDS9901 Ambient Light and
Proximity sensors. which are very similar to existing part with slightly
different integration time choices. Includes removal of driver for these
parts from drivers/misc.
vishay,veml3328
- New driver for this RGB+IR light sensor.
Features
--------
IIO Core
- Support for IEEE 754 floating point values in buffer scan elements.
- Support quaternion axis representation (missing the scaler part)
microchip,mcp4821
- Add configurable gain control
qcom,pm8xxx-xoadc
- Add per channel labels.
st,lsm6dsx
- Support for rotation sensing on the LSM6DSV and LSM6DSV16X using
both floating point and new quaterionaxis rotation modifier.
MAINTAINERS update
------------------
IIO top level entry
- Include Documentation/driver-api/iio/
adi,*
- Top level ADI entry maintainer switch from Lars-Peter Clausen to Nuno Sá
reflecting what has been the reality for some time. Thanks to Lars-Peter
who was very active for many years, but has moved on to other things.
Also add the linux@analog.com email list to ensure we don't get a gap
in future.
- Maintainer updates to reflect Cosmin Tanislav having moved on - thanks
to Marcelo Schmitt for taking these over.
sensiron,scd30
- Replace maintainer (Tomasz Duszynski) with Maxwell Doose.
Cleanups, minor fixes and hardening.
------------------------------------
Documentation
- Add missing powerdown modes to ABI docs.
- Use modern helpers for buffer definition in the examples.
core
- Rework of the handling of timestamps so that the offset is cached at
buffer resize time (during enabling) rather than based on assumption
that relied in the timestamp being last and the largest element and
so always 8 bytes before end of the scan. Underlying problem was
triggered by scans with repeated type elements such as quaternions
with each element more than 2 bytes - Giving a 16 byte+ aligned channel
with result that a following timestamp may be 16 bytes from end of scan,
rather than 8. Note that for the bosch,bno55 a compatibility hack means
that it will duplicate the timestamp putting a second copy at previously
incorrect location.
- Tidy up use of kernel types in buffer code to not use int64_t given all
calls use s64.
various drivers
- Drop unused driver_data in device id tables - includes cleanup of various
drivers that had only one choice where it can be hard coded elsewhere.
- Move to named initializers for many i2c_device_id and platform_device_id
tables (I have no idea how we go into habit of using named initializers
for only a subset of the table types - e.g. of_device_id).
- Make IIO_CHAN_SOFT_TIMESTAMP() macro a compound literal allowing simple
use in various drivers that do dynamic channel definitions. Use it in
all such cases.
- Use dev_err_probe() and local dev variables to tidy up older drivers.
- Switch more drivers to devm_mutex_init() to provide minor debug benefits.
- Reorder code to put MODULE_DEVICE_TABLE() next to the tables.
- Lots of use of cleanup.h magic to improve code flow, often including
related refactors such as introducing helpers.
- Replacement of usleep_range() with fsleep()
- Reduce logging noise where functions either provide their own extensive
reports on error, or where a clear error code is returned to userspace.
- Minor spelling and style fixes (improving bracket usage, not using
__packed etc)
hid-sensors-*
- Drop helpers for setting channel bit masks in favor of a compound
literal at the call site. Also general cleanup of surrounding code.
hid-sensors-magn
- Use u32 rather than bare unsigned for types.
hid-sensors-rotation
- Make sue of ext_scan_type handling for static case rather than duplicate
chan_info structures.
adi,ad3552r
- Use field_get() to replace open coded equivalent.
adi,ad4170
- Switch from switch to table lookup for GPIO modes.
adi,ad5686
- Apply IWYU principal to included a consistent set of headers.
- Deduplicate regmaps for AD5684 and AD5693 as identical.
- Switch from an enum value in driver data and array look up to pointers
to separate structures, improving readabilty and avoiding issues with
0 value when using helpers to deal with different firmware types.
- Add of_match_id table to SPI driver rather than relying on fallback to
spi_device_id table.
- Introduce some helpers for powerdown mask control.
- Add helpers for control sync simplifying a couple of corner cases.
- Docs fixes.
- Add an ops structure to simplify future addition of operations beyond
read and write.
adi,ad7191
- Switch to best practice of using device_property_present() to detect
if an optional property is there rather than error values on querying
the property.
adi,ad7280a
- Use local variables to improve readability of breaking up chan-address.
adi,ad7825
- Cleanup a type mismatch in clamp() call.
adi,ad799x
- Include improvements
- Local dev variable to shorten code lines.
- Cache regulator voltage at probe (these never change in practice)
- Convert to devm for all unwind handling.
adi,ad9832
- Improve include relevance including replacing kernel.h with more specific
headers.
- Simplify some maths.
adi,ad9834
- Improve include relevance including replacing kernel.h with more specific
headers.
adi,adt7316
- Add a comment to avoid future 'fixes' for error handling during the
odd sequence used to flip from I2C mode to SPI mode.
adi,adxl*
- Documentation consistency improvements.
asahi-kasei,ak8975
- Fix missing runtime pm calls for buffered capture.
- Fix missing pm_runtime_put_autosuspend() in an error path that would leave
the device stuck on.
- Close a potential uninitialized kernel stack leak.
- Extensive driver modernization including: header relevance, fsleep()
various minor bugs, dropping duplicate error messages and avoiding
magic lengths for buffers.
- Replace opencoded polling with iopoll().
- Add error checking to gpio reads.
avia,hx711
- Move scale computation from global data to per device avoiding problems
if multiple devices present.
- General binding text cleanup.
bosch,bmg160
- Add missing mount-matrix entry to binding.
bosch,bno55
- Terminate error strings with newlines.
devantech,srf08
- Replace sprintf() with sysfs_emit() and sysfs_emit_at() to make intent
clearer.
freescale,mma8452
- Add missing return value check.
- Fix potential probe ordering issue by switching to non devm irq request.
linear,ltc2309
- Add chip specific read delays.
- Improve chip_info structure, adding __counted_by_ptr marking and
reorganizing to improve packing.
linear,ltc2983
- Fix a firmware combination where default n_wires of 2 bypasses exclusion
of adi,current-rotate whereas explicitly setting it to 2 does not.
- Fix potential race with completion reinit.
- Improve error message wording consistency.
- Use fwnode_property_present() to detect optional properties rather
than fragile return value checking.
microchip,mcp3422
- Use of GENMASK(), FIELD_GET(), FIELD_PREP() to improve readability and
generally modernize driver.
microchip,mcp47feb02
- Fix binding example to use a possible I2C address.
- Fix binding bounds on channel number.
- Standardize binding example indentation
nxp,saradc
- Increase chances of recovering from a failure in the interrupt handler
by notifying the trigger that it can reenable even when the read failed.

- Replace custom timestamp channel macro with main one.
sciosense,ens210
- Now scoped_guard() has been reworked, no need for a return
that can never be reached.
sensiron,scd30
- Constify command lookup table.
- Sanity check for NULL buffer of non zero size being provided to
sc30_i2c_command()

During staging and delete, measurements are not completely deallocated.
Their entry digest portion is kept and is still reachable with the hash
table to detect duplicate records. If the number of records is significant,
this reduces the memory saving benefit of staging.
Some users might be interested in achieving the best memory saving (the
measurements are completely deallocated) at the cost of having duplicate
records across the staged measurement lists. Duplicate records are still
avoided within the current measurement list.
Introduce the new kernel option ima_flush_htable to decide whether or not
the digests of staged measurement records are flushed from the hash table,
when they are deleted, to achieve the maximum memory saving.
When the option is enabled, replace the old hash table with a new one,
by calling ima_alloc_replace_htable(), and completely delete the
measurements records.

Now that inode->i_ino stores the full 64-bit NFS fileid, the
nfs_compat_user_ino64() function is no longer needed.
generic_fillattr() already copies inode->i_ino into stat->ino, so the
explicit override in nfs_getattr() is also redundant.
Also remove the now-unused nfs_fileid_to_ino_t() and
nfs_fattr_to_ino_t() helper functions that were used to XOR-fold
64-bit fileids into the old unsigned long i_ino.
Keep the enable_ino64 module parameter as a deprecated stub that
accepts but ignores the value, logging a notice when set. This avoids
breaking existing configurations that pass nfs.enable_ino64 on the
kernel command line or in modprobe.d.

The conservative governor documentation incorrectly states that setting
freq_step to 0 will use the default 5% frequency step. In reality, since
at least commit 8e677ce83bf4 ("[CPUFREQ] conservative: fixup governor to
function more like ondemand logic"), freq_step=0 has always caused the
governor to skip frequency updates entirely.
Correct the documentation to reflect the actual behavior: freq_step=0
disables frequency changes by the governor entirely.

Convert the xtfpga I2S controller plain-text binding documentation
to standard dt-schema.
The hardware requires exactly one memory region, one interrupt line,
and one phandle to the master clock. Verified these constraints against
the driver source in sound/soc/xtensa/xtfpga-i2s.c.
Also explicitly define the '#sound-dai-cells' property, as it is
required for audio routing but was omitted from the original
text properties list.
