The existing write_unlock_ip procfs interface releases NLM file
locks held by a specific client IP address, but procfs provides
no structured way to extend that operation to other scopes such as
revoking NFSv4 state.
Add NFSD_CMD_UNLOCK_IP as a dedicated netlink command for
releasing NLM locks by client address. The command accepts a
binary sockaddr_in or sockaddr_in6 in its address attribute.
The handler validates the address family and length, then calls
nlmsvc_unlock_all_by_ip() to release matching NLM locks. Because
lockd is a single global instance, that call operates across
all network namespaces regardless of which namespace the caller
inhabits.
A separate netlink command for filesystem-scoped unlock is added in
a subsequent commit.
The nfsd_ctl_unlock_ip tracepoint is updated from string-based
address logging to __sockaddr, which stores the binary sockaddr
and formats it with %pISpc. This affects both the new netlink path
and the existing procfs write_unlock_ip path, giving consistent
structured output in both cases.

The bridge chain format selection behaviour was, until now,
undocumented. With the addition of the "color format" DRM property, it's
not sufficiently complex enough that documentation is warranted,
especially for driver authors trying to do the right thing.
Add a high-level overview of how the process is supposed to work, and
mention what the display driver is supposed to do if it wants to make
use of this functionality.

Add a new general DRM property named "color format" which can be used by
userspace to request the display driver to output a particular color
format.
Possible string values for the new enum property are:
- "AUTO" (setup by default, driver internally picks the color format)
- "RGB"
- "YUV 4:4:4"
- "YUV 4:2:2"
- "YUV 4:2:0"
Drivers should advertise from this list the formats they support in an
optimistic best-case scenario. EDID data from the sink can then be used
in the kernel's atomic check phase to restrict this set of formats, as
well as by userspace to make a correct choice in the first place.

The LTC4283 is a negative voltage hot swap controller that drives an
external N-channel MOSFET to allow a board to be safely inserted and
removed from a live backplane.
Special note for the "adi,vpower-drns-enable" property. It allows to choose
between the attenuated MOSFET drain voltage or the attenuated input
voltage at the RTNS pin (effectively choosing between input or output
power). This is a system level decision not really intended to change at
runtime and hence is being added as a Firmware property.

Extend the raspberrypi-hwmon driver to expose firmware-provided
voltage measurements through the hwmon subsystem.
The driver now exports the following voltage inputs:
- in0_input (core)
- in1_input (sdram_c)
- in2_input (sdram_i)
- in3_input (sdram_p)
Voltage values returned by firmware are converted from microvolts
to millivolts as expected by the hwmon subsystem.
Update the documentation related to it.
The existing undervoltage sticky alarm handling is preserved and
associated with the first voltage channel.

The Murata D1U74T-W series are hot-pluggable 1U AC/DC front-end
power supplies in the Intel CRPS-185 / OCP M-CRPS form factor.
Each variant delivers a 12 V main output plus a 12 V standby output
from a wide AC input (90-264 Vac) or HVDC supply, and includes an
internal variable-speed cooling fan and on-board voltage, current,
power, fan-speed, and temperature telemetry.
The host-side digital interface is a PMBus 1.2 port on I2C. The
PSU's other electrical signals (status, alert, current-share) live
on the CRPS edge connector and are consumed by the chassis
controller rather than the host SoC, so there are no host-described
supplies, GPIOs, clocks, or interrupts. Add the compatible to
trivial-devices.yaml rather than carrying a standalone binding file.

The nct7802 chip exposes two registers that allow setting the time
interval between successive duty increases or decreases in Smart Fan
mode. The units are intervals of 0.1 second. The default value at power
on is 10, so 1 second.
Add sysfs attributes for step_up_time and step_down_time to allow
controlling the responsiveness of the fan speed. Values are represented
as milliseconds to the user. When set, the value is clamped to the valid
range of 100 to 25500 (0.1 to 25.5 seconds), and rounded to the nearest
multiple of 100.

Add hwmon driver for the ARCTIC Fan Controller, a USB HID device
(VID 0x3904, PID 0xF001) with 10 fan channels. Exposes fan speed in
RPM (read-only) and PWM duty cycle (0-255, read/write) via sysfs.
The device pushes IN reports at ~1 Hz containing RPM readings. PWM is
set via OUT reports; the device applies the new duty cycle and sends
back a 2-byte ACK (Report ID 0x02). The driver waits up to 1 s for
the ACK using a completion. Measured device latency: max ~563 ms over
500 iterations. PWM control is manual-only: the device never changes
duty cycle autonomously.
raw_event() may run in hardirq context, so fan_rpm[] is protected by
a spinlock with irq-save. pwm_duty[] is also protected by this spinlock
because reset_resume() clears it outside the hwmon core lock. The OUT
report buffer is built and write_pending is armed under the same lock so
that no reset_resume() can race with the pwm_duty[] snapshot. priv->buf
is exclusively accessed by write(), which the hwmon core serializes.

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.
