1* SiRF SoC audio port
2
3Required 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.
9
10  One of the DMA channels will be responsible for transmission (should be
11  named "tx") and one for reception (should be named "rx").

13Example:
14
15audioport: audioport@b0040000 {
16	compatible = "sirf,audio-port";
17	reg = <0xb0040000 0x10000>;
18	dmas = <&dmac1 3>, <&dmac1 8>;
19	dma-names = "rx", "tx";
20};
