2026-04-10hwmon: pmbus: Add support for Sony APS-379Chris Packham-0/+58
Add pmbus support for Sony APS-379 power supplies. There are a few PMBUS commands that return data that is undocumented/invalid so these need to be rejected with -ENXIO. The READ_VOUT command returns data in linear11 format instead of linear16 so we need to workaround this.

2026-04-03hwmon: (yogafan) Add support for Lenovo Yoga/Legion fan monitoringSergio Melas-0/+131
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.

2026-03-30hwmon: (it87) Add support for IT8689EMarkus Hoffmann-6/+20
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.

2026-03-25hwmon: (adm1177) fix sysfs ABI violation and current unit conversionSanman Pradhan-4/+4
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.

2026-01-23Documentation: use a source-read extension for the index link boilerplateJani Nikula-7/+0
The root document usually has a special :ref:`genindex` link to the generated index. This is also the case for Documentation/index.rst. The other index.rst files deeper in the directory hierarchy usually don't. For SPHINXDIRS builds, the root document isn't Documentation/index.rst, but some other index.rst in the hierarchy. Currently they have a ".. only::" block to add the index link when doing SPHINXDIRS html builds. This is obviously very tedious and repetitive. The link is also added to all index.rst files in the hierarchy for SPHINXDIRS builds, not just the root document. Put the boilerplate in a sphinx-includes/subproject-index.rst file, and include it at the end of the root document for subproject builds in an ad-hoc source-read extension defined in conf.py. For now, keep having the boilerplate in translations, because this approach currently doesn't cover translated index link headers.

2025-11-18hwmon: Add Apple Silicon SMC hwmon driverJames Calligeros-0/+72
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.
