I can't find where it was documented at the moment, but I seem to remember
reading somewhere that the iMX6 SoC version of this IP doesn't support
audio with non-CEA modes - though, maybe that's a result of the limited
TMDS clocks which are supported.

This is a change which will need testing on iMX6.
