hwmon: (pmbus/tps53679) Add support for TPS53622 and TPS53659

2026-09-02T21:38:38+00:00

TPS53622 and TPS53659 are dual-channel D-CAP+ step-down controllers that use the VID VOUT format and VOUT_MODE identification like the existing TPS53679/TPS53688, so they reuse tps53679_identify(). Shorten the Kconfig prompt to the family name and list the supported chips in the help text instead; this also adds TPS53685, which is already supported by the driver but was missing from the list. Update the driver documentation, including the per-attribute lists, and fix an existing "TPS53588" typo (should be TPS53688) in those lists.

hwmon: Add Minisforum UM780 XTX EC monitoring and fan control

2026-09-02T21:36:56+00:00

Add a DMI-gated hwmon driver for the embedded controller used by the Minisforum UM780 XTX with board revision 1.1 and BIOS 1.06. Expose the CPU and system fan control temperatures and tachometers. The tachometer protocol returns one byte per OEM command, so serialize transactions and use high-low-high sampling to reject torn values. Allow selecting either complete OEM CPU fan profile through pwm1_enable and changing the two validated system fan transition temperatures through standard automatic-curve attributes. Cache coherent settings and restore them after the firmware reloads defaults following resume.

hwmon: (spd5118) Avoid probing when 16-bit addressing is enabled

2026-09-02T21:36:56+00:00

Support for 16-bit addressing was removed when support for i3c was added to the driver. Switching between 8-bit and 16-bit addressing might confuse the system firmware, so we are forced to bail out if 16-bit addressing was configured during boot.

hwmon: (spd5118) Select page 0 unconditionally during probe

2026-09-02T21:36:56+00:00

Some Intel i2c controllers can be configured by the BIOS to reject writes to the SPD device. This often causes problems when the register page needs to be changed, usually during resume. Avoid probing on affected devices by unconditionally selecting page 0 by writing the SPD5118_REG_I2C_LEGACY_MODE register during probe. This will fail on affected controllers and thus prevent the driver from probing.

hwmon: (asus-ec-sensors) add ROG STRIX X670E-A GAMING WIFI

2026-09-02T21:36:38+00:00

The ROG STRIX X670E-A GAMING WIFI is missing from the driver's DMI table. Consequently, the board lookup fails with -ENODEV, asus_ec_sensors does not load, and no asusec hwmon device or EC temperature readings are available. The board uses the same EC sensors, access mutex, and AMD 600-series register layout as the ROG STRIX X670E-E GAMING WIFI. Add its DMI entry using the existing X670E-E board information and document the board as supported. Before the change, there was no asusec device under /sys/class/hwmon and there were no EC readings. After the change, the driver registered four sensors with representative readings of 57-61 C for CPU, 68-71 C for CPU package, 43-44 C for motherboard, and 49-52 C for VRM. The readings correlated with nct6775 and k10temp. Repeated polling with both hwmon drivers loaded produced no EC access, bank-switch, concurrent access, or locking errors. Tested on an ASUS ROG STRIX X670E-A GAMING WIFI with BIOS 2704.

hwmon: it87: add IT8613E support

2026-09-02T21:36:38+00:00

Teach the Super I/O probe path to recognize IT8613E and add its hardware monitoring configuration. Add feature flags, 11 mV ADC scaling, the IT8665-style PWM register map, six PWM temperature mapping sources, and GPIO pin-mux checks. Only three temperature inputs are currently known, so retain the existing three temperature limit and offset resources. Document the chip in the hwmon guide.
