From 2fd3eec19c6e0a2c218853db9df27d4e74921673 Mon Sep 17 00:00:00 2001 From: Aleksa Savic Date: Sun, 27 Feb 2022 21:56:25 +0100 Subject: hwmon: (aquacomputer_d5next) Add support for Aquacomputer Farbwerk 360 Extend aquacomputer_d5next driver to expose hardware temperature sensors of the Aquacomputer Farbwerk 360 RGB controller, which communicates through a proprietary USB HID protocol. Four temperature sensors are available. Additionally, serial number and firmware version are exposed through debugfs. This driver has been tested on x86_64.
