But Oh, there's definitely going to be a platform-specific hook to configure things. The platform needs to specify how the devices that make up the audio subsystem are interconnected on the board, and that's done in kernel since it depends on the hardware and can potentially lead to physical damage if done incorrectly. > otherwise, I think that'd work for audio - the only question is whether > we need it to be more generic. Agreed.
