The controller has a dma controller for one playback buffer. It can play the stream to both I2S and SPDIF interfaces with independent mute.

Now, for example, I have a board with i2s codec and spdif tx diode connected to the above controller:

DMA (platform) -+-> I2S (dai) ----> I2S_Codec (codec) | +-> SPDIF (dai) --> SPDIF_TX (codec)

Is there any way in the current ASoC API to have the above setup?

As discussed on IRC this is probably best represented using soc-pcm at the minute.
