* hwmon: (aspeed-g6-pwm-tacho): Support for ASPEED g6 PWM/Fan tachBilly Tsai2024-03-072-0/+27
| | | | | | | | | | | | | | The driver support two functions: PWM and Tachometer. The PWM feature can handle up to 16 output ports, while the Tachometer can monitor to up to 16 input ports as well. This driver implements them by exposing two kernel subsystems: PWM and HWMON. The PWM subsystem can be utilized alongside existing drivers for controlling elements such as fans (pwm-fan.c), beepers (pwm-beeper.c) and so on. Through the HWMON subsystem, the driver provides sysfs interfaces for fan.

* hwmon: Add driver for ASUS ROG RYUJIN II 360 AIO coolerAleksa Savic2024-02-252-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* hwmon: Add driver for NZXT Kraken X and Z series AIO CPU coolersAleksa Savic2024-02-252-0/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* hwmon: Add support for Amphenol ChipCap 2Javier Carrasco2024-02-252-0/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* hwmon: Drop non-functional I2C_CLASS_HWMON support for drivers w/o detect()Heiner Kallweit2024-02-111-1/+0
| | | | | | | | | | | | | | | 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(). Class-based probing is a legacy mechanism, in addition apparently nobody ever noticed that class-based probing has been non-functional in both drivers from the very beginning. So drop the fragments of class-based probing support.

* hwmon: (max31827) Add custom attribute for resolutionDaniel Matyas2023-12-111-6/+23
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | SMM665 and related chips are power controller/sequencer chips from Summit Microelectronics. The company was acquired by Qualcomm in 2012, and support for the chip series stopped. The chips are long since gone from active use, making the driver unsupportable and just consuming space and compile time. Remove it. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

* hwmon: (oxp-sensors) Add tt_toggle attribute on supported boardsJoaquín Ignacio Aramendía2023-06-171-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | OneXPlayer boards from the last generation (both for OneXPlayer and AOK ZOE brands) have a toggle in the EC to switch the "Turbo/Silent" button into a different keyboard event. Add a means to use that "Turbo button takeover" function and expose it to userspace in a custom sysfs `tt_toggle` attribute. It can be read to take the current state. Write 1|0 to activate the function. The specific keycode is dependent on the board but can be checked by running `evtest` utility. Newer BIOS on the OneXPlayer added this function aside from string changes. Add a board enum to differentiate it from the old OneXplayer Mini AMD BIOS.

* hwmon: add HP WMI Sensors driverJames Seo2023-06-082-0/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hewlett-Packard (and some HP Compaq) business-class computers report hardware monitoring information via WMI. This driver exposes that information to hwmon. Initial support is provided for temperature, fan speed, and intrusion sensor types. Provisional support is provided for voltage and current sensor types. HP's WMI implementation permits many other types of numeric sensors. Therefore, a debugfs interface is also provided to enumerate and inspect all numeric sensors visible on the WMI side. This should facilitate adding support for other sensor types in the future. Tested on a HP Z420, a HP EliteOne 800 G1, and a HP Compaq Elite 8300 SFF. Note that provisionally supported sensor types are untested and seem to be rare-to-nonexistent in the wild, having been encountered neither on test systems nor in ACPI dumps from the Linux Hardware Database. They are included because their popularity in general makes their presence on past or future HP systems plausible and because no doubt exists as to how the sensors themselves would be represented in WMI (alarm attributes will need to wait for hardware to be located). A 2005 HP whitepaper gives the relevant sensor object MOF definition and sensor value scaling calculation, and both this driver and the official HP Performance Advisor utility comply with them (confirmed in the latter case by reverse engineering).

Implemented by Noah Bergbauer [1]. Two temperature sensors are exposed, along with pressure (current, min, max and target), reservoir volume (total and filled), pump speed and flow. Pump speed and flow values are user provided and allow the Leakshield to optimize its operation. Writing them to the device is subject of future patches.
