Hmm...I think, if "samsung,<ip name>-<ip version>" is possible, it would be
nice. I remember there are no versions in datasheet for some IPs but
something have like i2s and mfc. So "samsung,<ip>-<version>" is used for
only i2s and mfc. But actually there are versions for Samsung IPs, no
comments for that in datasheet. So I think, if Samsung can provide the
specific version of Samsung IPs, we can use that like other platforms. I
will prepare some table for that after meeting with Samsung hardware IP team
so that samsung platform use one format "samsung,<ip>-<version>".
