This really doesn't seem like something that ought to go into the DT and hence ABI given that there's obviously no reason to use this in production. Just make it be a #define in the code or something.
It would be nice to have this as an optional devicetree property so when testing JACK latency etc I don't have to manually re-compile a kernel...
You'll have to rebuild your DT anyway, I'm not sure the kernel is that much of a difference... For your use case you'd want a regular runtime ALSA control, not a DT property anyway. That would be fine.
