Koen Vandeputte efb362cd93 imx6: disable dma on uart ... When this target got updated to 4.14, this patch got removed to re-evaluate if it was still needed. Extensive testing now shows this issue is still present. Let's re-add the patch to fix it for now. As the uart bus is very low bandwidth .. performance impact is negligible. Boot log: [ 22.513051] imx-uart 2020000.serial: DMA transaction error. [ 22.522721] imx-uart 2020000.serial: DMA transaction error. As a sidenote: The patch mentiones an issue with RS485, but the bootlog errors above were recorded with the uart ports in standard RS232 mode.
