in line with an earlier comment, the primary/secondary terminology seem to
reflect how things are called in the datasheet (which only talks about a
primary/secondary master clock, otherwise about mi2sN). How about calling
these nodes 'dai-link@N' as in the binding (and a bunch of other
boards/SoCs)?
Okay. will change accordingly.

Detter put this at the end as many other nodes do, rather than
'hiding' it inmidst of the hardware description.
