Then you will see a message from the kernel saying that no external SDMA firmware could be found and that the internal one is going to be used. >> Also, could you try bumping the SSI and SDMA clock rates at the maximum? > > Any idea how I do that? I guess it's in the .dtsi file perhaps? I'll > poke around. You can try to call clk_set_rate() with the maximum allowed frequency inside the ssi driver. I don't recall on top of my head what is this value though.
