ASoC machine driver is a Linuxism.

I'd expect something else in here like phandle links to sub blocks. This 
alone just for purposes of instantiating a driver is not acceptible.

Don't use '_' in node names, just 'codec@...'.

Bindings describe h/w, not ASoC or drivers.

Just i2s@... Though 0 here is not valid without a reg property. There's 
no registers?

What's the difference between this and the previous one.

Now I'm confused. How does this relate to the machine driver above? An 
overview of the audio subsystem and its components would be helpful.

Again, why the indexing here?
