As you are aware, this can't work with iMX6 SoCs.  We need to come up with
some way to deal with the different IP cores in a sane way.

The "codec" part of this IP is different between the two implementations;
your ASoC codec driver is not useful on the iMX6 SoC implementation.

We need to find a way to allow these two implementations to co-exist
sanely.
