| 3 | Required properties: |
| 4 | - compatible: Should be "sprd,pcm-platform". |
| 5 | - dmas: Specify the list of DMA controller phandle and DMA request line ordered pairs. |
| 6 | - dma-names: Identifier string for each DMA request line in the dmas property. |
| 7 | These strings correspond 1:1 with the ordered pairs in dmas. |

| 9 | Example: |
| 10 | |
| 11 | audio_platform:platform@0 { |
| 12 | compatible = "sprd,pcm-platform"; |
| 13 | dmas = <&agcp_dma 1 1>, <&agcp_dma 2 2>, |
| 14 | <&agcp_dma 3 3>, <&agcp_dma 4 4>, |
| 15 | <&agcp_dma 5 5>, <&agcp_dma 6 6>, |
| 16 | <&agcp_dma 7 7>, <&agcp_dma 8 8>, |
| 17 | <&agcp_dma 9 9>, <&agcp_dma 10 10>; |
| 18 | dma-names = "normal_p_l", "normal_p_r", |
| 19 | "normal_c_l", "normal_c_r", |
| 20 | "voice_c", "fast_p", |
| 21 | "loop_c", "loop_p", |
