This is the first major patch I've ever done with the intention of introducing a new module, so it's highly likely I've made some mistakes or misunderstood something. TL;DR: 1. introduce new module to contain bios attributes, using fw_attributes_class 2. deprecate all possible attributes from asus-wmi that were added ad-hoc 3. remove those in the next LTS cycle The idea for this originates from a conversation with Mario Limonciello https://lore.kernel.org/platform-driver-x86/371d4109-a3bb-4c3b-802f-4ec27a945c99@xxxxxxx/ It is without a doubt much cleaner to use, easier to discover, and the API is well defined as opposed to the random clutter of attributes I had been placing in the platform sysfs. There is some discussion on-going regarding the way tuning knobs such as the PPT_* should work with platform_profile. This may result in the creation of an extra profile type "Custom" to signify that the user has adjusted things away from the defaults used by profiles such as "balanced" or "quiet".
