hwmon: (aquacomputer_d5next) Add support for Aquacomputer Quadro fan controller
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.
