Hi Folker,

Thanks for the clarification — I misunderstood about custom drivers.

I have confirmed that we are using the upstream xilinx DMA driver (drivers/dma/xilinx/xilinx_dma.c)
and using AXI DMA for audio. We use separate fixed-direction channels:
MM2S for playback (DMA_MEM_TO_DEV) and S2MM for capture (DMA_DEV_TO_MEM), referenced
via device tree.

Thanks,
Rahul Navale
