-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@...10000 {
-		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>;
