Why not just do these one time at probe, we don't undo them when we shut
the DAI down?
If I do that Am afraid that the driver would loose the flexibility of
selecting different MI2S from DT level. Hardcoding which MI2S can got to
external or internal codec is something that I wanted to avoid from the
start.
I will add the shutdown code to reset the configuration.

It'd be clearer if this were part of the above code (which should still
be written as a switch statement) - I was just asking myself what
happens if we fall off the end of the if/else chain.
I will change this to switch case.

If this is all the property is doing why not just put a link name
property in the DT rather than this? That makes the driver a bit more
general and is more idiomatic.
Yes, it makes it more clear with link-name property. I will fix this in
next version.
+ dai_link->name = dai_link->stream_name = name;
Write two assignment statements, it's clearer and more idiomatic.
I will fix this too.
