     1 * Amlogic Audio SPDIF Input
    2 
    3 Required properties:
    4 - compatible: 'amlogic,axg-spdifin' or
    5               'amlogic,g12a-spdifin' or
    6               'amlogic,sm1-spdifin'
    7 - interrupts: interrupt specifier for the spdif input.
    8 - clocks: list of clock phandle, one for each entry clock-names.
    9 - clock-names: should contain the following:
   10   * "pclk" : peripheral clock.
   11   * "refclk" : spdif input reference clock
   12 - #sound-dai-cells: must be 0.
   13 
   14 Optional property:
   15 - resets: phandle to the dedicated reset line of the spdif input.
   16 
   17 Example on the A113 SoC:
   18 
   19 spdifin: audio-controller@400 {
   20         compatible = "amlogic,axg-spdifin";
   21         reg = <0x0 0x400 0x0 0x30>;
   22         #sound-dai-cells = <0>;
   23         interrupts = <GIC_SPI 87 IRQ_TYPE_EDGE_RISING>;
   24         clocks = <&clkc_audio AUD_CLKID_SPDIFIN>,
   25                  <&clkc_audio AUD_CLKID_SPDIFIN_CLK>;
   26         clock-names = "pclk", "refclk";
   27 };
