* Spreadtrum DMA platfrom bindings
|
|
|
|
Required properties:
|
|
- compatible: Should be "sprd,pcm-platform".
|
|
- dmas: Specify the 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.
|
|
|
|
Example:
|
|
|
|
audio_platform:platform@0 {
|
|
compatible = "sprd,pcm-platform";
|
|
dmas = <&agcp_dma 1 1>, <&agcp_dma 2 2>,
|
|
<&agcp_dma 3 3>, <&agcp_dma 4 4>,
|
|
<&agcp_dma 5 5>, <&agcp_dma 6 6>,
|
|
<&agcp_dma 7 7>, <&agcp_dma 8 8>,
|
|
<&agcp_dma 9 9>, <&agcp_dma 10 10>;
|
|
dma-names = "normal_p_l", "normal_p_r",
|
|
"normal_c_l", "normal_c_r",
|
|
"voice_c", "fast_p",
|
|
"loop_c", "loop_p",
|
|
"voip_c", "voip_p";
|
|
};
