    1 Device-Tree bindings for Xilinx PL audio formatter
    2 
    3 The IP core supports DMA, data formatting(AES<->PCM conversion)
    4 of audio samples.
    5 
    6 Required properties:
    7  - compatible: "xlnx,audio-formatter-1.0"
    8  - interrupt-names: Names specified to list of interrupts in same
    9                     order mentioned under "interrupts".
   10                     List of supported interrupt names are:
   11                     "irq_mm2s" : interrupt from MM2S block
   12                     "irq_s2mm" : interrupt from S2MM block
   13  - interrupts-parent: Phandle for interrupt controller.
   14  - interrupts: List of Interrupt numbers.
   15  - reg: Base address and size of the IP core instance.
   16  - clock-names: List of input clocks.
   17    Required elements: "s_axi_lite_aclk", "aud_mclk"
   18  - clocks: Input clock specifier. Refer to common clock bindings.
   19 
   20 Example:
   21         audio_ss_0_audio_formatter_0: audio_formatter@80010000 {
   22                 compatible = "xlnx,audio-formatter-1.0";
   23                 interrupt-names = "irq_mm2s", "irq_s2mm";
   24                 interrupt-parent = <&gic>;
   25                 interrupts = <0 104 4>, <0 105 4>;
   26                 reg = <0x0 0x80010000 0x0 0x1000>;
   27                 clock-names = "s_axi_lite_aclk", "aud_mclk";
   28                 clocks = <&clk 71>, <&clk_wiz_1 0>;
   29         };
