Hi Mark,
+- loopback: if this property is present then the dai is configured in
loopback mode where the output fifo is redirected to the inputfifo.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...
