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.
