* hwmon: Add driver for Renesas HS3001Andre Werner2023-08-211-0/+10
| | | | | | | | | | | | | | | | | | | | | Add base support for Renesas HS3001 temperature and humidity sensors and its compatibles HS3002, HS3003 and HS3004. The sensor has a fix I2C address 0x44. The resolution is fixed to 14bit (ref. Missing feature). Missing feature: - Accessing non-volatile memory: Custom board has no possibility to control voltage supply of sensor. Thus, we cannot send the necessary control commands within the first 10ms after power-on.

* hwmon: Remove smm665 driverGuenter Roeck2023-08-211-14/+0
| | | | | | | | | | | 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: add HP WMI Sensors driverJames Seo2023-06-081-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* hwmon: Add MAX31827 driverDaniel Matyas2023-06-081-0/+11
| | | | | | | | | | | | | | | | MAX31827 is a low-power temperature switch with I2C interface. The device is a ±1°C accuracy from -40°C to +125°C (12 bits) local temperature switch and sensor with I2C/SM- Bus interface. The combination of small 6-bump wafer-lev- el package (WLP) and high accuracy makes this temper- ature sensor/switch ideal for a wide range of applications.

Currently only AMD boards are supported since Intel have different EC registers and values to read/write. Fan control is provided via pwm interface in the range [0-255]. AMD boards have [0-100] as range in the EC, the written value is scaled to accommodate for that.

The cache For JC42_REG_TEMP is dropped (regmap can't cache it because it's volatile, meaning it can change at any time) as well for simplicity and consistency with other drivers.

| | | | | | | | | | | | | | | | | | | | | | | Extend aquacomputer_d5next driver to expose hardware temperature sensors and fans of the Aquacomputer Quadro fan controller, which communicates through a proprietary USB HID protocol. Implemented by Jack Doan [1]. Four temperature sensors and PWM controllable fans are available. The liquid flow sensor is also exposed, implemented by Leonard Anderweit [2]. Additionally, serial number, firmware version and power-on count are exposed through debugfs. This driver has been tested on x86_64.

| | | | | | | | | | | | | | | | | | All chips supported by the ADM1021 driver are also supported by the LM90 driver. Make that support official. After this change, the adm1021 driver is only needed if the lm90 driver is disabled. Also, the adm1021 driver misdetects a variety of chips as MAX1617A, which is unwanted if any of those chips is in the system. For this reason. make the adm1021 driver dependent on !SENSORS_LM90 to show that it is not needed if the lm90 driver is enabled, and to avoid misdetection if a chip supported by the lm90 driver is in the system. Devicetree nodes are not added for the added chips since it is quite unlikely that such old chips will ever be used in a devicetree based system. They can be added later if needed.

Also mention ON Semiconductor NCT210, which is pin and register compatible to ADM1021A. None of the chips support the secondary manufacturer and chip ID registers at 0x3e and 0x3f, but return 0 when reading from those registers.

| | | | | | | | | | | | | | | | MAX1617 and LM84 are stripped-down versions of LM90, so they can easily be supported by the LM90 driver. The most difficult part is chip detection, since those old chips do not support manufacturer ID or chip ID registers. The "alarms" attribute is enabled for both chips to match the functionality of the adm1021 driver. Chip detection was improved and is less prone to misdetection than the chip detection in the adm1021 driver.

| | | | | | | | | | | | | | | | MAX6642 is a reduced version of LM90 with no low limits and no conversion rate register. Its alert functionality is broken, similar to many other chips supported by the lm90 driver. After this change, the stand-alone max6642 driver is only needed if the lm90 driver is disabled. Make it dependent on SENSORS_LM90=n to show that it is not needed if the lm90 driver is enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | ADT7481, ADT7482, and ADT7483 are similar to ADT7461, but support two external temperature sensors, similar to MAX6695/6696. They support an extended temperature range similar to ADT7461. Registers for the second external channel can be accessed directly or by using the same method as used by MAX6695/6696. For simplicity, the access method implemented for MAX6695/6696 is used. The chips support PEC (packet error checking). Set the PEC feature flag and let the user decide if it should be enabled or not (it is by default disabled). Even though it is only documented for ADT7483, all three chips support a secondary manufacturer ID register at 0x3e and a chip ID register at 0x3f. Use the contents of those registers register for improved chip detection accuracy. Add the same check to the ADT7461A detection code since this chip also supports the same (undocumented) registers. Devicetree nodes are not added for the added chips since it is quite unlikely that such old chips will ever be used in a devicetree based system. They can be added later if needed.
