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.

Long Cheng (4):
  dt-bindings: dma: uart: add uart dma bindings
  dmaengine: mtk_uart_dma: add Mediatek uart DMA support
  serial: 8250-mtk: add uart DMA support
  arm: dts: mt2701: add uart APDMA to device tree
