   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"

  23         spdif: spdif@0x77400000 {
  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";
