The INA238 family supports eight conversion time steps from 50 us to
4120 us (SQ52206: 66 us to 8230 us). At the millisecond granularity of
update_interval, the four shortest steps (50, 84, 150, 280 us) all
round to the same value and cannot be individually selected.
Add support for the generic update_interval_us attribute, which reports
and programs the same ADC cycle time as update_interval but in
microseconds, giving userspace full access to all conversion time steps.
Both attributes reflect the total cycle time including the active
averaging count: the reported value is the raw conversion time
multiplied by the number of averaged samples, and writes apply the
inverse mapping.

Some hardware monitoring chips support update intervals below one
millisecond. The existing update_interval attribute uses millisecond
granularity, which causes sub-millisecond steps to round to the same
value and become inaccessible from userspace.
Introduce update_interval_us, a companion chip-level attribute that
expresses the same update interval in microseconds. Drivers
implementing this attribute should also implement update_interval for
compatibility with millisecond-based userspace interfaces.

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 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.

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.

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.

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,

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.

Add hardware monitoring support for the LattePanda Sigma SBC
(DFRobot, ITE IT8613E EC). The driver reads fan speed and
temperatures via direct port I/O, as the BIOS disables the
ACPI EC interface.

* Make sysfs entries documentation easier to maintain.
* Use multi-line enum.
* Correct "has_power_average" comment.
Create a new "has_update_interval" member for chips which support
averaging.

As noticed in the discussion [1] the Baikal SoC and platforms
are not going to be finalized, hence remove stale code.

The adm1177 driver exposes the current alert threshold through
hwmon_curr_max_alarm. This violates the hwmon sysfs ABI, where
*_alarm attributes are read-only status flags and writable thresholds
must use currN_max.
The driver also stores the threshold internally in microamps, while
currN_max is defined in milliamps. Convert the threshold accordingly
on both the read and write paths.
Widen the cached threshold and related calculations to 64 bits so
that small shunt resistor values do not cause truncation or overflow.
Also use 64-bit arithmetic for the mA/uA conversions, clamp writes
to the range the hardware can represent, and propagate failures from
adm1177_write_alert_thr() instead of silently ignoring them.
Update the hwmon documentation to reflect the attribute rename and
the correct units returned by the driver.

temperature
The hwmon sysfs ABI expects tempN_crit_hyst to report the temperature at
which the critical condition clears, not the hysteresis delta from the
critical limit.
The peci cputemp driver currently returns tjmax - tcontrol for
crit_hyst_type, which is the hysteresis margin rather than the
corresponding absolute temperature.
Return tcontrol directly, and update the documentation accordingly.

This reverts commit 443b39c82c322c9f3c38bea0389fe927ba00b3b4.
I was just informed that this product is discontinued (without being
ever released to the market). Pull the plug and let's not waste any more
maintainers time.
