That's fine, the driver can just use the compatible string to check this and not offer any of the DSP related stuff (it should do this regardless of the method used here). I'm guessing the regmap configs should also be different. > What if there was an ALSA control instead that passed in the firmware name > from the user space instead of using the DT? > Then the control can load and parse the firmware and wait for the user to > select the program. > This would solve a user from having ot update the DT to use a firmware. That's really not very idiomatic for how Linux does stuff and seems to pretty much guarantee issues with hotplugging controls and ordering - you'd need special userspace to start up even if it was just a really simple DSP config doing only speaker correction or something. I'm not sure what the advantage would be - what problem is this solving over static names?
