Subject: [PATCH 0/4] add uart DMA function 

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
