-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>;
- };
