   3 Required properties:
   4 - compatible: "sirf,audio-port"
   5 - reg: Base address and size entries:
   6 - dmas: List of DMA controller phandle and DMA request line ordered pairs.
   7 - dma-names: Identifier string for each DMA request line in the dmas property.
   8   These strings correspond 1:1 with the ordered pairs in dmas.

  15 audioport: audioport@b0040000 {
  16         compatible = "sirf,audio-port";
  17         reg = <0xb0040000 0x10000>;
  18         dmas = <&dmac1 3>, <&dmac1 8>;
  19         dma-names = "rx", "tx";
  20 };
