In Mediatek SOCs, the uart can support DMA function. Base on DMA engine formwork, we add the DMA code to support uart. And put the code under drivers/dma. This series contains document bindings, Kconfig to control the function enable or not, device tree including interrupt and dma device node, the code of UART DMA function.
