ASoC: Updates for v6.17 There's a few new drivers here and quite a lot of cleanup work from Morimoto-san but generally this has been quite a quiet release, resulting in a fairly small diffstat. Highlights include: - Refactoring of the Kconfig menus to be hopefully more consistant and easier to navigate. - Refactoring of the DAPM code, mainly hiding functionality that doesn't need to be exposed to drivers. - Removal of the unused upstream weak paths DAPM functionality. - Further work on the generic handling for SoundWire SDCA devices. - Cleanups of our usage of the PM autosuspend functions, this pulls in some PM core changes on a shared tag. - Support for AMD ACP7.2 and SoundWire on ACP 7.1, Fairphone 4 & 5, various Intel systems, Qualcomm QCS8275, Richtek RTQ9124 and TI TAS5753.
