How to support multi FIFO address in ALSA & DMA Engine?

Hi Experts

Some cpu-dai devices support multi FIFO, so we need to tell DMA which fifos and how many fifos it should fill the data to.

For example, when channels = 2, only one fifo is used. when channels = 4, then two fifos are used.

or when channels = 2, two fifos are used, when channels= 4, four fifos are used.

But in snd_dmaengine_dai_dma_data, and dma_slave_config, there is only one dma address. Do you have any idea to support multi FIFO? is there any implemented reference?
