No clue if the original DTS change should be reverted or these are in fact DMA coherent, but let's choose one path... https://lore.kernel.org/linux-devicetree/254c1d14-25e3-4f4c-9e79-4ef7cec4d22f@linaro.org/T/#t Best regards, Krzysztof

I don't understand your comment. Did you read the link above? Anyway, I was asking: are you testing the patches before sending? Best regards, Krzysztof
