From: Mario Limonciello <mario.limonciello@xxxxxxx> When two drivers provide platform profile handlers but use different strings to mean (essentially) the same thing the legacy interface won't export them because it only shows profiles common to multiple drivers. This causes an unexpected behavior to people who have upgraded from an earlier kernel because if multiple drivers have bound platform profile handlers they might not be able to access profiles they were expecting. Introduce a compatibility mode to the core that when one driver supports quiet and the other supports low power that allows both to enter the appropriate mode. There have been some other attempts at solving this issue in other ways. This serves as an alternative to those attempts. v1 -> v2: * Drop hidden choices. * Just add compatibility to the core for low power and quiet modes Link: https://lore.kernel.org/platform-driver-x86/e64b771e-3255-42ad-9257-5b8fc6c24ac9@xxxxxx/T/#t Link: https://lore.kernel.org/platform-driver-x86/CAGwozwF-WVEgiAbWbRCiUaXf=BVa3KqmMJfs06trdMQHpTGmjQ@xxxxxxxxxxxxxx/T/#m2f3929e2d4f73cc0eedd14738170dad45232fd18 Link: https://lore.kernel.org/platform-driver-x86/20250228170155.2623386-1-superm1@xxxxxxxxxx/ Cc: Antheas Kapenekakis <lkml@xxxxxxxxxxx> Cc: "Luke D.
