The delayed polling work rearms itself from the work function, so use
explicit delayed-work setup and cleanup instead of
devm_delayed_work_autocancel().
Initialize the delayed work with INIT_DELAYED_WORK() and register a
devres cleanup action that calls disable_delayed_work_sync() during
teardown.
This addresses the concern raised during review about the polling work
being able to requeue itself while the driver is being removed.

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.

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 driver currently passes a stack-allocated buffer to spi_write(),
which is incompatible with DMA on systems with CONFIG_VMAP_STACK

Move the transfer buffer into the driver's private data structure
to ensure it is DMA-safe. Since this shared buffer now requires
serialization, this change depends on the previous commit which
migrated the driver to the hwmon 'with_info' API.
While moving the logic, also:
- Corrected the sign extension for 14-bit data by casting to s16.
- Scaled the output to millivolts (2500mV full scale
) to comply with the hwmon ABI.
