Device-Tree bindings for Xilinx SPDIF IP
The IP supports playback and capture of SPDIF audio
Required properties:
- compatible: "xlnx,spdif-2.0"
- clock-names: List of input clocks.
Required elements: "s_axi_aclk", "aud_clk_i"
- clocks: Input clock specifier. Refer to common clock bindings.
- reg: Base address and address length of the IP core instance.
- interrupts-parent: Phandle for interrupt controller.
- interrupts: List of Interrupt numbers.
- xlnx,spdif-mode: 0 :- receiver mode
1 :- transmitter mode
- xlnx,aud_clk_i: input audio clock value.
Example:
spdif_0: spdif@80010000 {
clock-names = "aud_clk_i", "s_axi_aclk";
clocks = <&misc_clk_0>, <&clk 71>;
compatible = "xlnx,spdif-2.0";
interrupt-names = "spdif_interrupt";
interrupt-parent = <&gic>;
interrupts = <0 91 4>;
reg = <0x0 0x80010000 0x0 0x10000>;
xlnx,spdif-mode = <1>;
xlnx,aud_clk_i = <49152913>;
};
