* hwmon: add driver for HTU31Andrei Lalaev2025-03-182-0/+38
| | | | | | | | | | | | Add base support for HTU31 temperature and humidity sensor. Besides temperature and humidity values, the driver also exports a 24-bit heater control to sysfs and serial number to debugfs.

* hwmon: Add Congatec Board Controller monitoring driverThomas Richard2025-03-172-0/+64
| | | | | | | | | | | | | | | Add support for the Congatec Board Controller. This controller exposes temperature, voltage, current and fan sensors. The available sensors list cannot be predicted. Some sensors can be present or not, depending the system. The driver has an internal list of all possible sensors, for all Congatec boards. The Board Controller gives to the driver its sensors list, and their status (active or not).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add initial support for the Texas Instruments TPS25990 eFuse. This adds the basic PMBUS telemetry support for the device. From Karol Przybylski: The tps25990_read_word_data function contains a block of unreachable code caused by the syntactic structure in the PMBUS_VIRT_READ_IIN_MAX case. Specifically, the return TPS25990_READ_IIN_PEAK; statement immediately exits the function, making the next lines unreachable. This patch removes the return statement, leaving the expected handling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Writing PMBus protected registers does succeed from the smbus perspective, even if the write is ignored by the device and a communication fault is raised. This fault will silently be caught and cleared by pmbus irq if one has been registered. This means that the regulator call may return succeed although the operation was ignored. With this change, the operation which are not supported will be properly flagged as such and the regulator framework won't even try to execute them.

| | | | | | | | | | | | INA260 is similar to other chips of the series, except it has an internal shunt resistor. The calibration register is therefore not present. Also, the current register address was changed, though that does not matter for the driver since the shunt voltage register (which is now the current register) value is already used to read the current.

* hwmon: Remove devm_hwmon_device_unregister() API functionGuenter Roeck2024-09-131-7/+0
| | | | | | | | | | | | devm_hwmon_device_unregister() has no in-tree user, and its implementation is wrong since it does not pass the to-be-removed hardware monitoring device as parameter. I do not envision a valid use for it; drivers needing it should not have called devm_hwmon_device_register_with_info() in the first place. Remove it.

* hwmon: (ina2xx) Add support for current limitsGuenter Roeck2024-08-301-0/+4
| | | | | | | | | | | | | While the chips supported by this driver do not directly support current limits, they do support setting shunt voltage limits. The shunt voltage divided by the shunt resistor value is the current. On top of that, calibration values are set such that in the shunt voltage register and the current register report the same values. That means we can report and configure current limits based on shunt voltage limits, and we can do so with much better accuracy than by setting shunt voltage limits.

* hwmon: (oxp-sensors) Add support for multiple new devices.Derek J. Clark2024-08-271-18/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the OrangePi NEO-01. It uses different registers for PWM manual mode, set PWM, and read fan speed than previous devices. Valid PWM input and duty cycle is 1-244, we scale this from 1-255 to maintain compatibility with the existing interface. Add OneXPlayer 2 series, OneXFly, and X1 series models. The 2/X1 series use new registers for turbo button takeover and read fan speed. X1 has an Intel variant so change the CPU detection at init to only check for the affected devices. While at it, adjust formatting of some constants and reorder all cases alphabetically for consistency. Rename OXP_OLD constants to OXP_MINI for disambiguation. Update code comments for clarity. Add support for AYANEO models 2S, AIR 1S, Flip series, GEEK 1S, and KUN. Signed-off-by: Derek J.
