The initial proposed solution was to allow a flexible dma-names order in the binding, due to potential ABI breakage concerns after fixing the DTS files. But luckily the Allwinner boards are not affected, since they are using a shared DMA channel for rx and tx. Hence, the first step in fixing the inconsistency was to change dma-names order in the binding to tx->rx. Do the same for the snps,dw-apb-uart nodes in the DTS file.
