The current fsl_qmc_audio works in interleaved mode. The audio samples are interleaved and all data are sent to (received from) one QMC channel. Using several QMC channels, non interleaved mode can be easily supported. In that case, data related to ch0 are sent to (received from) the first QMC channel, data related to ch1 use the next QMC channel and so on up to the last channel. In terms of constraints and settings, the two modes are slightly different: - Interleaved mode: - The sample size should fit in the number of time-slots available for the QMC channel. - The number of audio channels should fit in the number of time-slots (taking into account the sample size) available for the QMC channel. - Non-interleaved mode: - The number of audio channels is the number of available QMC channels. - Each QMC channel should have the same number of time-slots. - The sample size equals the number of time-slots of one QMC channel. Add support for the non-interleaved mode allowing multiple QMC channel per DAI. The DAI switches in non-interleaved mode when more that one QMC channel is available.
