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. Reported-by:

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. Reviewed-by:

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:

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. Signed-off-by:

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. [1]: https://github.com/liquidctl/liquidctl/pull/653 Tested-by:

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. Co-developed-by:

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. Signed-off-by:
