1Device-Tree bindings for Xilinx PL audio formatter
2
3The IP core supports DMA, data formatting(AES<->PCM conversion)
4of audio samples.
5
6Required 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.

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>;
