pdata->cpu_map[] saves the mapping between cpu core id and the index in pdata->core_data[]. This is used to find the temp_data structure using cpu_core_id, by traversing the pdata->cpu_map[] array. But the same goal can be achieved by traversing the pdata->core_temp[] array directly. Remove redundant pdata->cpu_map[]. No functional change. 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/653Tested-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:

The temperature/humidity sensors of the STS3x/SHT3x family are calibrated and factory-programmed with a unique serial number. For some sensors, this serial number can be used to obtain a calibration certificate via an API provided by the manufacturer (Sensirion). Expose the serial number via debugfs.

Using one or more external N-channel pass transistors, board supply voltage and inrush current are ramped up at an adjustable rate.

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. Signed-off-by:

HWMON_CHANNEL_INFO() is supposed to be used as initializer for arrays of const struct hwmon_channel_info *. However, without explicit const, HWMON_CHANNEL_INFO() creates mutable compound literals, and the const pointers point at the mutable data. Add const to place the data in rodata.
