1 ADI AXI-SPDIF controller
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"

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>;
