Your subject says it is v2 and previously it was v6. Make it consistent.

Fix your patchset threading. I don't think it's possible to apply your one.

you miss allOf with ref to saound-dai-common.

You said you can have here two addresses. You don't allow it, test it.
Missing minItems, but...

... So these are fixed? No need to encode them in such case...
and anyway actually I agree with Rob here - these addresses should be put in reg.

Probably you can figure it out from previous addresses and there is no need for this property.
