hwmon: (nct6775) Add support for NCT6122D

2026-09-11T01:03:23+00:00

The NCT6122D hardware monitor is the same as the NCT6126D, the only difference if the number of UARTs: two instead of six. Add it to the driver using the nct6126 chip kind to avoid code duplication.

hwmon: (nct6775) Add support for NCT6126D

2026-09-11T01:03:23+00:00

Add support for the hardware monitoring functionality of the NCT6126D Super-I/O chip. The NCT6126D hardware monitor is nearly identical to the NCT6116D: the fan, PWM, temperature, TSI, alarm. The differences are: - Device IDs 0xd283 (A version) and 0xd284 (B version), which both fall into the NCT6116D ID range (0xd280) when masked with SIO_ID_MASK. Instead, compare the full value to distinguish from NCT6116D. - One additional VIN: VHIF scaled at 16 mV/LSB. - The fan count limit registers are documented for all five fans. Also expose fan4_min.

hwmon: arctic_fan_controller: default PWM cache to MCU 40%

2026-09-11T01:03:23+00:00

The device has no GET_REPORT and every OUT report carries all 10 channels, so the cache has to start at some value. Starting at 0 means the first sysfs write to a single channel also sends 0% on the other nine. The MCU factory default is 40%. Initialize pwm_duty[] to 102 (40% on the 0-255 sysfs scale) at probe and on reset-resume. Any initial cache can be stale if the module is reloaded without a device reset. 40% matches the hardware after power-on or power-loss resume, and a first single-channel write leaves the fans running at a safe speed. PWM is still not taken from periodic IN reports: the device is manual-only and the host cache stays authoritative after the first successful write.

hwmon: (hih6130) Replace sprintf() with sysfs_emit()

2026-09-11T01:03:23+00:00

Use sysfs_emit() instead of sprintf() in the sysfs show functions hih6130_temperature_show() and hih6130_humidity_show() to use the preferred kernel interface for writing to sysfs buffers. No functional change intended. Note: Not runtime tested due to lack of hardware.

hwmon: axiado-tsadc: Add AX3000/AX3005 TSADC support

2026-09-11T01:03:23+00:00

Add a hwmon driver for the temperature sensor ADC (TSADC) controller found on Axiado AX3000 and AX3005 SoCs. The controller measures temperature at locations within the SoC silicon die. Each TSADC controller is registered as a separate hwmon device and exposes one read-only temperature channel. The sensor is configured for continuous conversion during probe. The current TSADC hardware does not support threshold or alarm reporting. All TSADC interrupt sources are masked during initialization, and only the current temperature is exposed through temp1_input. The averaged 12-bit ADC code is converted to millidegrees Celsius using a lookup table with linear interpolation between adjacent entries. Raw values outside the characterized lookup-table range are clamped to the nearest supported temperature.

hwmon: (pmbus/ltc4286) Add writable shunt_resistor sysfs attribute

2026-09-11T01:03:23+00:00

The LTC4286/LTC4287 driver uses rsense to scale current and power telemetry. rsense is board-specific rather than a fixed device characteristic, and may differ across qualified BOM variants using the same software image. If rsense does not match the installed board configuration, current and power readings are mis-scaled. Add a writable shunt_resistor sysfs attribute so userspace can update the board calibration value after platform identification. Initialize rsense from shunt-resistor-micro-ohms as before (or the existing default when absent), and validate runtime updates before recalculating the current/power scaling coefficients.

hwmon: (asus_rog_ryujin) Add ROG Ryujin III 360

2026-09-11T01:03:23+00:00

Add the USB product ID of the base ASUS ROG RYUJIN III 360 (0b05:1aa2, USB product string "ROG RYUJIN III"). It uses the same status report layout and cooler duty channel as the RYUJIN III EXTREME, EVA and WHITE editions, so it can share rog_ryujin_iii_info. Tested on a ROG RYUJIN III 360: coolant temperature, pump speed and internal fan speed report plausible values that track load, and the internal fan follows pwm2 (30% -> 870 RPM, 40% -> 1590 RPM).
