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>;
|
|
};
