hwmon: (pwm-fan) Switch regulator dynamically

2022-09-25T21:22:11Z

This adds the enable attribute which is used to select if zero PWM duty means to switch off regulator and PWM or to keep them enabled but at inactive PWM output level. Depending on the select enable mode, turn off the regulator and PWM if the PWM duty is zero, or keep them enabled. This is especially important for fan using inverted PWM signal polarity. Having regulator supplied and PWM disabled, some PWM controllers provide the active, rather than inactive signal. With this change the shutdown as well as suspend/resume paths require modifcations as well.

hwmon: (aquacomputer_d5next) Add support for Aquacomputer High Flow Next

2022-09-19T13:17:06Z

Extend aquacomputer_d5next driver to expose various hardware sensors of the Aquacomputer High Flow Next flow sensor, which communicates through a proprietary USB HID protocol. The High Flow Next exposes +5V voltages, water quality, conductivity and flow readings. A temperature sensor can be connected to it, in which case it provides its reading and an estimation of the dissipated/absorbed power in the liquid cooling loop. Additionally, serial number and firmware version are exposed through debugfs. Registry offsets were discovered and tested by users on Github [1] [2].

hwmon: (max31790) add fanN_enable

2022-09-19T13:17:05Z

The MAX31790 has a tach input enable bit in each fan's configuration register. This is only enabled by the driver if RPM mode is selected, but the driver doesn't provide a way to independently enable tachometer input regardless of the regulator mode. By adding the fanN_enable sysfs files, we can decouple the tach input from the regulator mode. Also update the documentation.

hwmon: (aquacomputer_d5next) Add support for reading virtual temp sensors

2022-09-19T13:17:05Z

Add support for reading virtual temperature sensors for the D5 Next, Octo, Quadro and Farbwerk 360. Virtual temperature sensors are written to the device by the user, pulling from an arbitrary value source. Writing to them is not yet reverse engineered, so the only way to set them for now is to use the official software.
