* SiRF SoC audio port
Required properties:
- compatible: "sirf,audio-port"
- reg: Base address and size entries:
- dmas: List of DMA controller phandle and DMA request line ordered pairs.
- dma-names: Identifier string for each DMA request line in the dmas property.
These strings correspond 1:1 with the ordered pairs in dmas.
One of the DMA channels will be responsible for transmission (should be
named "tx") and one for reception (should be named "rx").
Example:
audioport: audioport@b0040000 {
compatible = "sirf,audio-port";
reg = <0xb0040000 0x10000>;
dmas = <&dmac1 3>, <&dmac1 8>;
