We really shouldn't need dummy DAIs at all I think, if we do it feels like there's a problem. It's quite possible that there is actually a problem here though...
It's dummy in the droid4 voice call case as mcbsp is not the clock-master and there's nothing to configure for mcbsp.
If the McBSP is doing anything at all it should still be properly represented with the actual device rather than a dummy otherwise we'll most likely get confused at some point. If it's not doing anything then we shouldn't even need the dummy. But perhaps I'm confused about this particular system, I remember some of the OMAP designs were a bit fun.
But I guess in some cases mcbsp could be the clock-master and then the secondary DAI would have ops.
It'd be a bit of an unusual clock design for a phone but yeah.
