2024-12-14hwmon: (pmbus/tps25990) Add initial supportJerome Brunet
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.

2024-12-14hwmon: (pmbus/core) improve handling of write protected regulatorsJerome Brunet
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.

2024-12-14hwmon: (core) Avoid ifdef CONFIG_THERMAL in C source fileThomas Weißschuh
Using an #ifdef in a C source files to have different definitions of the same symbol makes the code harder to read and understand. Furthermore it makes it harder to test compilation of the different branches. Replace the ifdeffery with IS_ENABLED() which is just a normal conditional. The resulting binary is still the same as before as the compiler optimizes away all the unused code and definitions.

2024-11-13hwmon: (pmbus/isl68137) add support for voltage divider on VoutGrant Peltier
Some applications require Vout to be higher than the detectable voltage range of the Vsense pin for a given rail. In such applications, a voltage divider may be placed between Vout and the Vsense pin, but this results in erroneous telemetry being read back from the part. This change adds support for a voltage divider to be defined in the devicetree for a (or multiple) specific rail(s) for a supported digital multiphase device and for the applicable Vout telemetry to be scaled based on the voltage divider configuration. This change copies the implementation of the vout-voltage-divider devicetree property defined in the maxim,max20730 bindings schema since it is the best fit for the use case of scaling hwmon PMBus telemetry. The generic voltage-divider property used by many iio drivers was determined to be a poor fit because that schema is tied directly to iio and the isl68137 driver is not an iio driver.

2024-11-12hwmon: (pwm-fan) Introduce start from stopped state handlingMarek Vasut
Delta AFC0612DB-F00 fan has to be set to at least 30% PWM duty cycle to spin up from a stopped state, and can be afterward throttled down to lower PWM duty cycle. Introduce support for operating such fans which need to start at higher PWM duty cycle first and can slow down next. Introduce two new DT properties, "fan-stop-to-start-percent" and "fan-stop-to-start-us". The former describes the minimum percent of fan RPM at which it will surely spin up from stopped state. This value can be found in the fan datasheet and can be converted to PWM duty cycle easily. The "fan-stop-to-start-us" describes the minimum time in microseconds for which the fan has to be set to stopped state start RPM for the fan to surely spin up. Adjust the PWM setting code such that if the PWM duty cycle is below the minimum duty cycle needed by the fan to spin up from stopped state, then first set the PWM duty cycle to the minimum duty cycle needed by the fan to spin up from stopped state, then wait the time necessary for the fan to spin up from stopped state, and finally set the PWM duty cycle to the one desired by user.

2024-11-12hwmon: (pmbus/core) clear faults after setting smbalert maskJerome Brunet
pmbus_write_smbalert_mask() ignores the errors if the chip can't set smbalert mask the standard way. It is not necessarily a problem for the irq support if the chip is otherwise properly setup but it may leave an uncleared fault behind. pmbus_core will pick the fault on the next register_check(). The register check will fails regardless of the actual register support by the chip. This leads to missing attributes or debugfs entries for chips that should provide them. We cannot rely on register_check() as PMBUS_SMBALERT_MASK may be read-only. Unconditionally clear the page fault after setting PMBUS_SMBALERT_MASK to avoid the problem.

Convert all platform drivers below drivers/hwmonto use .remove(), with the eventual goal to drop struct platform_driver::remove_new().

Add support for manipulating the internal heater of sht4x devices. Enabling the heater removes condensed water from the sensor surface which disturbs the relative humidity measurements. The heater can operate at three heating levels (20, 110 or 200 milliwatts). Also, two heating durations may be selected (0.1 or 1s). Once the heating time elapses the heater is automatically switched off.

2024-11-10hwmon: (amc6821) add support for tsd,muleFarouk Bouabid
Theobroma Systems Mule is an MCU that emulates a set of I2C devices, among which is an amc6821 and other devices that are reachable through an I2C-mux. The devices on the mux can be selected by writing the appropriate device number to an I2C config register (amc6821: reg 0xff) Implement "tsd,mule" compatible to instantiate the I2C-mux platform device when probing the amc6821.

2024-11-10hwmon: (ina2xx) Add support for INA260Guenter Roeck
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.

2024-11-10hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König
These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While touching these structs, also remove commas after the sentinel entries and use a consistent indention style.
