1*4882a593Smuzhiyun* SiRF SoC audio port
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible: "sirf,audio-port"
5*4882a593Smuzhiyun- reg: Base address and size entries:
6*4882a593Smuzhiyun- dmas: List of DMA controller phandle and DMA request line ordered pairs.
7*4882a593Smuzhiyun- dma-names: Identifier string for each DMA request line in the dmas property.
8*4882a593Smuzhiyun  These strings correspond 1:1 with the ordered pairs in dmas.
9*4882a593Smuzhiyun
10*4882a593Smuzhiyun  One of the DMA channels will be responsible for transmission (should be
11*4882a593Smuzhiyun  named "tx") and one for reception (should be named "rx").

13*4882a593SmuzhiyunExample:
14*4882a593Smuzhiyun
15*4882a593Smuzhiyunaudioport: audioport@b0040000 {

18*4882a593Smuzhiyun	dmas = <&dmac1 3>, <&dmac1 8>;
19*4882a593Smuzhiyun	dma-names = "rx", "tx";
