+Device-Tree bindings for Xilinx PL audio formatter
+
+The IP core supports DMA, data formatting(AES<->PCM conversion)
+of audio samples.
+
+Required properties:
+ - compatible: "xlnx,audio-formatter-1.0"
+ - interrupt-names: Names specified to list of interrupts in same
+ order mentioned under "interrupts".
+ List of supported interrupt names are:
+ "irq_mm2s" : interrupt from MM2S block
+ "irq_s2mm" : interrupt from S2MM block
+ - interrupts-parent: Phandle for interrupt controller.
+ - interrupts: List of Interrupt numbers.
+ - reg: Base address and size of the IP core instance.
+ - clock-names: List of input clocks.
+ Required elements: "s_axi_lite_aclk", "aud_mclk"
+ - clocks: Input clock specifier. Refer to common clock bindings.
+
+Example:
+ audio_ss_0_audio_formatter_0: audio_formatter@80010000 {
+ compatible = "xlnx,audio-formatter-1.0";
+ interrupt-names = "irq_mm2s", "irq_s2mm";
+ interrupt-parent = <&gic>;
+ interrupts = <0 104 4>, <0 105 4>;
+ reg = <0x0 0x80010000 0x0 0x1000>;
+ clock-names = "s_axi_lite_aclk", "aud_mclk";
+ clocks = <&clk 71>, <&clk_wiz_1 0>;
+ };
