So what happens with your changes to everyone who is using a DT file with
the "samsung,i2s-v5" compatible string?

AFAIK we decided that current bindings, if broken, can be redone correctly, 
without caring for compatibility with old DTBs and only then, after 
reviewing these new bindings by DT people, they can be stabilized.

Other issue, though, is that this patch breaks things until they get fixed 
by patch 3. Support for new bindings should be added first, then users fixed 
and only then old bindings can be removed.

Best regards,
