Iow each McBSP have single DAI. Yeah it's single physical port for sure. But at least currently we need additional secondary DAIs for each TDM channel in addition to the primary DAI managing the McBSP registers. Currently there's nothing to do for the secondary DAIs, but if McBSP was also the clock master then the secondary DAI functions would need to take care of the multiplexing McBSP hardware resources. But that can be done later if we actually ever see some McBSP being TDM master use case.. Regards, Tony
