Description

Support reading from an I2S microphone and writing to an I2S speaker at the same time. Will require some architecture changes so that the parent I2S audio component handles configuring the audio settings. It should also improve the handling of I2S busses where its impossible to support duplex mode; e.g., the ATOM Echo has a PDM mic but a regular I2S speaker on the same bus, which are incompatible.
