This patch series adds support for the various features found on laptops manufactured by Uniwill. Those features are: - battery charge limiting - RGB lightbar control - hwmon support - improved hotkey support - keyboard-related settings This patch series is based on the following out-of-tree drivers: - https://github.com/pobrn/qc71_laptop - https://github.com/tuxedocomputers/tuxedo-drivers Additionally the OEM software of the Intel Nuc x15 was reverse-engineered to have a better understanding about the underlying hardware interface. The first patch introduces the uniwill-wmi driver used for handling WMI events on Uniwill devices. Due to a grave design error inside the underlying WMI firmware interface (the WMI GUID was copied from the Windows driver samples and is thus not unique) the driver cannot be autoloaded. Instead drivers using this module will load it as an module dependency. The second patch introduces the uniwill-laptop driver that does the majority of the work. This driver talks to the embedded controller yet another WMI interface to control the various features. Sadly this WMI firmware interfaces suffers from the exact same issue (the WMI GUID is not unique) and thus a DMI whitelist has to be used for loading the driver. The last patch finally adds some documentation for configuring and using both drivers. Special thanks go to: - github user cyear for bring up this topic on the lm-sensors issue tracker and being the tester for various prototype versions - github user dumingqiao for testing the battery, lightbar and keyboard-related features - Tuxedo computers for giving advice on how to design the userspace interface I send this series as an RFC to gather feedback and to request any involved developers if they want to have their Co-developed-by tags on the final patch series.
