On platforms which have smart speaker amplifiers connected via soundwire and modeled as aux devices in ASoC, in such usecases machine driver should be able to get sdw master stream from dai so that it can use the runtime stream to setup slave streams.
soundwire already as a set function, get function would provide more flexibility to above configurations.
