1 | * SiRF SoC audio port |
2 | ||
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. | |
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"). | |
12 | ||
13 | Example: | |
14 | ||
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 | }; |
