1ADI AXI-SPDIF controller 2 3Required 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 15For more details on the 'dma', 'dma-names', 'clock' and 'clock-names' properties 16please check: 17 * resource-names.txt 18 * clock/clock-bindings.txt 19 * dma/dma.txt 20 21Example: 22 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"; 30 }; 31
