2022-03-03hwmon: Add driver for Texas Instruments TMP464 and TMP468Guenter Roeck
Add support for Texas Instruments TMP464 and TMP468 temperature sensor ICs. TI's TMP464 is an I2C temperature sensor chip. This chip is similar to TI's TMP421 chip, but with 16bit-wide registers (instead of 8bit-wide registers). The chip has one local sensor and four remote sensors. TMP468 is similar to TMP464 but has one local and eight remote sensors.

2022-02-27hwmon: (lm70) Add ti,tmp125 supportChristian Lamparter
The TMP125 is a 2 degree Celsius accurate Digital Temperature Sensor with a SPI interface. The temperature register is a 16-bit, read-only register. The MSB (Bit 15) is a leading zero and never set. Bits 14 to 5 are the 1+9 temperature data bits in a two's complement format. Bits 4 to 0 are useless copies of Bit 5 value and therefore ignored. This was tested on a Aerohive HiveAP-350. Bonus: lm70 supports TMP122/TMP124 as well. I added them to the Kconfig module description.

2021-12-26hwmon: add driver for NZXT RGB&Fan Controller/Smart Device v2.Aleksandr Mezin
This driver implements monitoring and control of fans plugged into the device. Besides typical speed monitoring and PWM duty cycle control, voltage and current are reported for every fan. The device also has 2 connectors for RGB LEDs, support for them isn't implemented (mainly because there is no standardized sysfs interface). Also, the device has a noise sensor, but the sensor seems to be completely useless (and very imprecise), so support for it isn't implemented too. The driver coexists with userspace tools that access the device through hidraw interface with no known issues. The driver has been tested on x86_64, built in and as a module. Some changes/improvements were suggested by Jonas Malaco.

2021-12-26hwmon: (asus_wmi_ec_sensors) Support B550 Asus WMI.Denis Pauk
Linux HWMON sensors driver for ASUS motherboards to read sensors from the embedded controller. Many ASUS motherboards do not publish all the available sensors via the Super I/O chip but the missing ones are available through the embedded controller (EC) registers. This driver implements reading those sensor data via the WMI method BREC, which is known to be present in all ASUS motherboards based on the AMD 500 series chipsets (and probably is available in other models too). The driver needs to know exact register addresses for the sensors and thus support for each motherboard has to be added explicitly. The EC registers do not provide critical values for the sensors and as such they are not published to the HWMON.

2021-10-27hwmon: (tmp401) Drop support for TMP461Guenter Roeck
TMP461 is almost identical to TMP451, which is already supported by the lm90 driver. At the same time, unlike other sensors from the TMP401 compatible series, it only supports 8-bit temperature read operations, and it supports negative temperatures when configured for its default temperature range, and it supports a temperature offset register. Supporting this chip in the tmp401 driver adds unnecessary complexity. Remove its support from this driver and support the chip with the lm90 driver instead. Fixes: 24333ac26d01 ("hwmon: (tmp401) use smb word operations instead of 2 smb byte operations") Reported-by: David T. Wilson <david.wilson@nasa.gov> Cc: David T.

2021-10-27hwmon: (lm90) Add basic support for TI TMP461Guenter Roeck
TMP461 is almost identical to TMP451 and was actually detected as TMP451 with the existing lm90 driver if its I2C address is 0x4c. Add support for it to the lm90 driver. At the same time, improve the chip detection function to at least try to distinguish between TMP451 and TMP461. As a side effect, this fixes commit 24333ac26d01 ("hwmon: (tmp401) use smb word operations instead of 2 smb byte operations"). TMP461 does not support word operations on temperature registers, which causes bad temperature readings with the tmp401 driver. The lm90 driver does not perform word operations on temperature registers and thus does not have this problem. Support is listed as basic because TMP461 supports a sensor resolution of 0.0625 degrees C, while the lm90 driver assumes a resolution of 0.125 degrees C. Also, the TMP461 supports negative temperatures with its default temperature range, which is not the case for similar chips supported by the lm90 and the tmp401 drivers. Those limitations will be addressed with follow-up patches. Fixes: 24333ac26d01 ("hwmon: (tmp401) use smb word operations instead of 2 smb byte operations") Reported-by: David T.

2021-08-28hwmon: add driver for Aquacomputer D5 NextAleksa Savic
This driver exposes hardware sensors of the Aquacomputer D5 Next watercooling pump, which communicates through a proprietary USB HID protocol. Available sensors are pump and fan speed, power, voltage and current, as well as coolant temperature. Also available through debugfs are the serial number, firmware version and power-on count. Attaching a fan is optional and allows it to be controlled using temperature curves directly from the pump. If it's not connected, the fan-related sensors will report zeroes. The pump can be configured either through software or via its physical interface. Configuring the pump through this driver is not implemented, as it seems to require sending it a complete configuration. That includes addressable RGB LEDs, for which there is no standard sysfs interface. Thus, that task is better suited for userspace tools. This driver has been tested on x86_64, both in-kernel and as a module. Signed-off-by: Aleksa Savic <savicaleksa83@gmail.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2021-06-17hwmon: (max31790) Fix pwmX_enable attributesGuenter Roeck
pwmX_enable supports three possible values: 0: Fan control disabled. Duty cycle is fixed to 0% 1: Fan control enabled, pwm mode. Duty cycle is determined by values written into Target Duty Cycle registers. 2: Fan control enabled, rpm mode Duty cycle is adjusted such that fan speed matches the values in Target Count registers The current code does not do this; instead, it mixes pwm control configuration with fan speed monitoring configuration. Worse, it reports that pwm control would be disabled (pwmX_enable==0) when it is in fact enabled in pwm mode. Part of the problem may be that the chip sets the "TACH input enable" bit on its own whenever the mode bit is set to RPM mode, but that doesn't mean that "TACH input enable" accurately reflects the pwm mode. Fix it up and only handle pwm control with the pwmX_enable attributes. In the documentation, clarify that disabling pwm control (pwmX_enable=0) sets the pwm duty cycle to 0%. In the code, explain why TACH_INPUT_EN is set together with RPM_MODE. While at it, only update the configuration register if the configuration has changed, and only update the cached configuration if updating the chip configuration was successful.

2021-06-17hwmon: (max31790) Report correct current pwm duty cyclesGuenter Roeck
The MAX31790 has two sets of registers for pwm duty cycles, one to request a duty cycle and one to read the actual current duty cycle. Both do not have to be the same. When reporting the pwm duty cycle to the user, the actual pwm duty cycle from pwm duty cycle registers needs to be reported. When setting it, the pwm target duty cycle needs to be written. Since we don't know the actual pwm duty cycle after a target pwm duty cycle has been written, set the valid flag to false to indicate that actual pwm duty cycle should be read from the chip instead of using cached values.
