2024-02-25hwmon: Add driver for ASUS ROG RYUJIN II 360 AIO coolerAleksa Savic
This driver exposes hardware sensors of the ASUS ROG RYUJIN II 360 all-in-one CPU liquid cooler, which communicates through a proprietary USB HID protocol. Report offsets were initially discovered in [1] by Florian Freudiger. Available sensors are pump, internal and external (controller) fan speed in RPM, their duties in PWM, as well as coolant temperature. Attaching external fans to the controller is optional and allows them to be controlled from the device. If not connected, the fan-related sensors will report zeroes. The controller is a separate hardware unit that comes bundled with the AIO and connects to it to allow fan control. The addressable LCD screen is not supported in this driver and should be controlled through userspace tools.

2024-02-25hwmon: Add driver for NZXT Kraken X and Z series AIO CPU coolersAleksa Savic
This driver enables hardware monitoring support for NZXT Kraken X53/X63/X73 and Z53/Z63/Z73 all-in-one CPU liquid coolers. All models expose liquid temperature and pump speed (in RPM), as well as PWM control (natively only through a temp-PWM curve, but the driver also emulates fixed PWM control on top of that). The Z-series models additionally expose the speed and duty of an optionally connected fan, with the same PWM control capabilities. Pump and fan duty control mode can be set through pwm[1-2]_enable, where 1 is for the manual control mode and 2 is for the liquid temp to PWM curve mode. Writing a 0 disables control of the channel through the driver after setting its duty to 100%. As it is not possible to query the device for the active mode, the driver keeps track of it. The temperature of the curves relates to the fixed [20-59] C range, per device limitations, and correlating to the detected liquid temperature. Only PWM values (ranging from 0-255) can be set. The addressable RGB LEDs and LCD screen, included only on Z-series models, are not supported in this driver.

2024-02-25hwmon: Add support for Amphenol ChipCap 2Javier Carrasco
The Amphenol ChipCap 2 is a capacitive polymer humidity and temperature sensor with an integrated EEPROM and minimum/maximum humidity alarms. All device variants offer an I2C interface and depending on the part number, two different output modes: - CC2D: digital output - CC2A: analog (PDM) output This driver adds support for the digital variant (CC2D part numbers), which includes the following part numbers: - non-sleep measurement mode (CC2D23, CC2D25, CC2D33, CC2D35) - sleep measurement mode (CC2D23S, CC2D25S, CC2D33S, CC2D35S) The Chipcap 2 EEPROM can be accessed to configure a series of parameters like the minimum/maximum humidity alarm threshold and hysteresis. The EEPROM is only accessible in the command window after a power-on reset. The default window lasts 10 ms if no Start_CM command is sent. After the command window is finished (either after the mentioned timeout of after a Start_NOM command is sent), the device enters the normal operation mode and makes a first measurement automatically. Unfortunately, the device does not provide any hardware or software reset and therefore the driver must trigger power cycles to enter the command mode. A dedicated, external regulator is required for that. This driver keeps the device off until a measurement or access to the EEPROM is required, making use of the first automatic measurement to avoid different code paths for sleep and non-sleep devices. The minimum and maximum humidity alarms are configured with two registers per alarm: one stores the alarm threshold and the other one keeps the value that turns off the alarm. The alarm signals are only updated when a measurement is carried out.

2024-02-11hwmon: Drop non-functional I2C_CLASS_HWMON support for drivers w/o detect()Heiner Kallweit
Class-based I2C probing requires detect() and address_list both to be set in the I2C client driver, see checks in i2c_detect(). It's misleading to declare I2C_CLASS_HWMON support if the driver doesn't implement detect().

2024-01-02hwmon: (lm75) Add AMS AS6200 temperature sensorAbdel Alkuor
as6200 is a temperature sensor with 0.0625°C resolution and a range between -40°C to 125°C. By default, the driver configures as6200 as following: - Converstion rate: 8 Hz - Conversion mode: continuous - Consecutive fault counts: 4 samples - Alert state: high polarity - Alert mode: comparator mode Interrupt is supported for the alert pin.

2024-01-02hwmon: Add driver for Gigabyte AORUS Waterforce AIO coolersAleksa Savic
This driver exposes hardware sensors of the Gigabyte AORUS Waterforce all-in-one CPU liquid coolers, which communicate through a proprietary USB HID protocol. Report offsets were initially discovered in [1] and confirmed by me on a Waterforce X240 by observing the sent reports from the official software. Available sensors are pump and fan speed in RPM, as well as coolant temperature. Also available through debugfs is the firmware version. Attaching a fan is optional and allows it to be controlled from the device. If it's not connected, the fan-related sensors will report zeroes. The addressable RGB LEDs and LCD screen are not supported in this driver and should be controlled through userspace tools.

2023-12-11hwmon: (max31827) Add custom attribute for resolutionDaniel Matyas
Added custom channel-specific (temp1) attribute for resolution. The wait time for a conversion in one-shot mode (enable = 0) depends on the resolution. When resolution is 12-bit, the conversion time is 140ms, but the minimum update_interval is 125ms. Handled this problem by waiting an additional 15ms (125ms + 15ms = 140ms). Added 'mask' parameter to the shutdown_write() function. Now it can either write or update bits, depending on the value of mask. This is needed, because for alarms a write is necessary, but for resolution only the resolution bits should be updated.

MPS Flow Extend aquacomputer_d5next driver to expose various hardware sensors of the Aquacomputer High Flow USB flow sensor, which communicates through a proprietary USB HID protocol. This commit also adds support for the sensors of the MPS Flow devices, as they have the same USB product ID and sensor layouts. Implemented by Leonard Anderweit [1]. Internal and external temp sensor readings are available, along with the flow sensor. Additionally, serial number and firmware version are exposed through debugfs.
