A few things were changed in the process: - the dmas and dma-names properties are now required. - the ingenic,jz4770-uart and ingenic,jz4775-uart compatible strings now require the ingenic,jz4760-uart string to be used as fallback, since the hardware is compatible. - the ingenic,jz4725b-uart compatible string was added, with a fallback to ingenic,jz4740-uart.
