    1 Device-Tree bindings for Xilinx SPDIF IP
    2 
    3 The IP supports playback and capture of SPDIF audio
    4 
    5 Required properties:
    6  - compatible: "xlnx,spdif-2.0"
    7  - clock-names: List of input clocks.
    8    Required elements: "s_axi_aclk", "aud_clk_i"
    9  - clocks: Input clock specifier. Refer to common clock bindings.
   10  - reg: Base address and address length of the IP core instance.
   11  - interrupts-parent: Phandle for interrupt controller.
   12  - interrupts: List of Interrupt numbers.
   13  - xlnx,spdif-mode: 0 :- receiver mode
   14                     1 :- transmitter mode
   15  - xlnx,aud_clk_i: input audio clock value.
   16 
   17 Example:
   18         spdif_0: spdif@80010000 {
   19                 clock-names = "aud_clk_i", "s_axi_aclk";
   20                 clocks = <&misc_clk_0>, <&clk 71>;
   21                 compatible = "xlnx,spdif-2.0";
   22                 interrupt-names = "spdif_interrupt";
   23                 interrupt-parent = <&gic>;
   24                 interrupts = <0 91 4>;
   25                 reg = <0x0 0x80010000 0x0 0x10000>;
   26                 xlnx,spdif-mode = <1>;
   27                 xlnx,aud_clk_i = <49152913>;
   28         };
