optimize the MOSFET safe operating area (SOA). The SOA timer limits MOSFET
temperature rise for reliable protection against overstresses.

e28d0c73d4 hwmon: add driver for ARCTIC Fan Controller
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.

7e91691466 hwmon: add AMD Promontory 21 xHCI temperature sensor support
Add an auxiliary-bus hwmon driver for the temperature sensor exposed by
AMD Promontory 21 (PROM21) xHCI PCI functions. The driver binds to the
"hwmon" auxiliary device published by the PROM21 xHCI PCI glue and
exposes the sensor as temp1_input under the prom21_xhci hwmon device.

The sensor is accessed through a PROM21 vendor index/data register pair
in the xHCI PCI MMIO BAR. The driver consumes parent-provided MMIO data
from the PROM21 PCI glue instead of inspecting the parent PCI driver's
drvdata. The read path restores the previous vendor index value after
sampling and does not runtime-resume the parent PCI device; reads from a
suspended parent return -ENODATA.

Document the supported device, register access, runtime PM behavior, and
sysfs lookup method. The documentation also records the observation
method used to identify the register pair and derive the conversion
formula.

c67c248ca4 hwmon: (yogafan) Add support for Lenovo Yoga/Legion fan monitoring
This driver provides fan speed monitoring for Lenovo Yoga, Legion, and
IdeaPad laptops by interfacing with the Embedded Controller (EC) via ACPI.

To address low-resolution sampling in Lenovo EC firmware, a Rate-Limited
Lag (RLLag) filter is implemented. The filter ensures a consistent physical
curve regardless of userspace polling frequency.

Hardware identification is performed via DMI-based quirk tables, which
map specific ACPI object paths and register widths (8-bit vs 16-bit)
deterministically.

66b8eaf8de hwmon: (it87) Add support for IT8689E
Add support for the ITE IT8689E Super I/O chip. The IT8689E supports
newer autopwm, 12mV ADC, 16-bit fans, six fans, six PWM channels,
PWM frequency 2, six temperature inputs, AVCC3, temperature offset,
and fan on/off control.

Give it8689 its own GPIO configuration block in it87_find() rather
than sharing the it8620/it8628 block. The shared block reads
IT87_SIO_PINX2_REG and either marks IN3 as internal AVCC or skips
IN9. Because it8689 declares FEAT_AVCC3, IN9 is already marked as
always-internal before the GPIO block is reached; applying the PINX2
check would either create duplicate AVCC labels on IN3 and IN9 or
incorrectly skip IN9.

Also update Documentation/hwmon/it87.rst and drivers/hwmon/Kconfig to
document the newly supported chip.

663eb8763c i3c: simplify combined i3c/i2c dependencies
All combined i2c/i3c drivers appear to suffer from the same link
time problem when CONFIG_I3C is set to 'm':

arm-linux-gnueabi-ld: drivers/iio/magnetometer/mmc5633.o: in function `mmc5633_i3c_driver_init':
mmc5633.c:(.init.text+0x30): undefined reference to `i3c_driver_register_with_owner'

This was previously fixed every time by marking individual
drivers as 'depends on I2C; depends on I3C || !I3C', but this gets
tedious and is somewhat confusing.

Add a Kconfig symbol 'I3C_OR_I2C' to help replace those dependencies,
and use this in all the existing drivers that had already fixed it
as well as the new mmc5633 driver.

785205fd81 hwmon: Add Apple Silicon SMC hwmon driver
The System Management Controller on Apple Silicon devices is responsible
for integrating and exposing the data reported by the vast array of
hardware monitoring sensors present on these devices. It is also
responsible for fan control, and allows users to manually set fan
speeds if they so desire. Add a hwmon driver to expose current,
power, temperature, and voltage monitoring sensors, as well as
fan speed monitoring and control via the SMC on Apple Silicon devices.

The SMC firmware has no consistency between devices, even when they
share an SoC. The FourCC keys used to access sensors are almost
random. An M1 Mac mini will have different FourCCs for its CPU core
temperature sensors to an M1 MacBook Pro, for example. For this
reason, the valid sensors for a given device are specified in a
child of the SMC Devicetree node. The driver uses this information
to determine which sensors to make available at runtime.

0c7d530a04 hwmon: Add TSC1641 I2C power monitor driver
Add a driver for the ST Microelectronics TSC1641 16-bit high-precision
power monitor. The driver supports reading bus voltage, current, power,
and temperature. Sysfs attributes are exposed for shunt resistor and
update interval. The driver integrates with the hwmon subsystem and
supports optional ALERT pin polarity configuration.

3eaf1b6315 hwmon: (aht10) Add support for dht20
Add support for dht20 temperature and humidity sensor from Aosong.
Modify aht10 driver to handle different init command for dht20 sensor by
adding init_cmd entry in the driver data. dht20 sensor is compatible with
aht10 hwmon driver with this change.

Tested on TI am62x SK board with dht20 sensor connected at i2c-2 port.

d5f7411411 gpio updates for v6.18-rc1
GPIO core:
 - add support for sparse pin ranges to the glue between GPIO and pinctrl
 - use a common prefix across all GPIO descriptor flags for improved
   namespacing
 
 New drivers:
 - add new GPIO driver for the Nuvoton NCT6694
 - add new GPIO driver for MAX7360
 
 Driver improvements:
 - add support for Tegra 256 to the gpio-tegra186 driver
 - add support for Loongson-2K0300 to the gpio-loongson-64bit driver
 - refactor the gpio-aggregator module to expose its GPIO forwarder API
   to other in-kernel users (to enable merging of a new pinctrl driver
   that uses it)
 - convert all remaining drivers to using the modernized generic GPIO chip
   API and remove the old interface
 - stop displaying global GPIO numbers in debugfs output of controller
   drivers
 - extend the gpio-regmap helper with a new config option and improve its
   support for GPIO interrupts

Merge tag 'gpio-updates-for-v6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "There are two new drivers and support for more models in existing
  ones.

  The generic GPIO API has been reworked and all users converted
  which allowed us to move the fields specific to the generic GPIO
  implementation out of the high-level struct gpio_chip into its own
  structure that wraps the gpio_chip.

  Other than that, there's nothing too exciting. Mostly minor tweaks and
  fixes all over the place, some refactoring and some small new features
  in helper modules.

  GPIO core:
   - add support for sparse pin ranges to the glue between GPIO and
     pinctrl
   - use a common prefix across all GPIO descriptor flags for improved
     namespacing

   - add new GPIO driver for the Nuvoton NCT6694

9b96f82c78 hwmon: Add KEBA fan controller support
The KEBA fan controller is found in the system FPGA of KEBA PLC devices.
It detects if the fan is removed or blocked. For fans with tacho signal
the monitoring of the speed of the fan is supported. It also supports to
regulate the speed of fans with PWM input.

The auxiliary device for this driver is instantiated by the cp500 misc
driver.

platform/x86: oxpec: Move hwmon/oxp-sensors to platform/x86
The EC of OneXPlayer devices used to only control the fan. This is no
longer the case, with the EC of OneXPlayer gaining additional
functionality (turbo button, turbo led, battery controls).

As it will be beneficial from a complexity perspective to retain this
driver as a single unit, move it out of hwmon, and into platform/x86.
Also, remove the hwmon documentation to prepare moving it to
Documentation/ABI/.

While at it, add myself to the maintainer's file.
