hwmon: add driver for Aquacomputer D5 Next

2021-08-28T15:53:30+00:00

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 Signed-off-by: Guenter Roeck

hwmon: (max31790) Fix pwmX_enable attributes

2021-06-17T11:21:46+00:00

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.
