Yeah, it's not terribly clever either way.  We've been using the version
numbers in audio for a long time partly because it is documented
sometimes and partly because most of the SoCs tend to have one fully
featured controller and a bunch of secondary controllers on older IP

It was explicitly identified as I2Sv4 in the S3C6410 datasheet so no
real issue there.
