If it's only that I'm sure we could spare a i.MX53 LOCO ;)

Right now the i.MX audmux binding is only enough to say which ports
should be connected, but not which format should be used. Just today
we had the problem where a codec has two DAIs and wanted to add the
information on which port our SSI unit is connected to the devicetree.
So I think it's worthwile to do, but that would be a big big task...
