| 2 | |
| 3 | Required properties: |
| 4 | - compatible : Must be "adi,axi-spdif-tx-1.00.a" |
| 5 | - reg : Must contain SPDIF core's registers location and length |
| 6 | - clocks : Pairs of phandle and specifier referencing the controller's clocks. |
| 7 | The controller expects two clocks, the clock used for the AXI interface and |
| 8 | the clock used as the sampling rate reference clock sample. |
| 9 | - clock-names: "axi" for the clock to the AXI interface, "ref" for the sample |
| 10 | rate reference clock. |
| 11 | - dmas: Pairs of phandle and specifier for the DMA channel that is used by |
| 12 | the core. The core expects one dma channel for transmit. |
| 13 | - dma-names : Must be "tx" |
| 14 | |

| 23 | spdif: spdif@77400000 { |
| 24 | compatible = "adi,axi-spdif-tx-1.00.a"; |
| 25 | reg = <0x77600000 0x1000>; |
| 26 | clocks = <&clk 15>, <&audio_clock>; |
| 27 | clock-names = "axi", "ref"; |
| 28 | dmas = <&ps7_dma 0>; |
| 29 | dma-names = "tx"; |
