minimum: 0
maximum: 15
and drop that one sentence.

The same in other places.

s/slave/secondary/

This is some odd indentation. Please use standard, like example-schema
is showing, so:

description:
Child nodes for a standalone audio codec or speaker amplifier IC.
RX and TX Soundwire slave devices.

It looks you used such pattern in other places here - they should also
be corrected.
