Now we have the same subject for patches 2 and 3.
Personally, I'd prefer "dt-bindings: sound: blah...", but not enough to
argue with Mark about it. If that is not the prefix, then it should at
least have "binding" in the subject.

Drop this and just make compatible doc above like this:
- compatible : Must be one of:
"zte,zx296718-i2s", "zte,zx296702-i2s"
"zte,zx296702-i2s"

BTW, this should be "i2s@0b005000". No trailing 0 on i2s and no leading
0 on unit-address.
