Bindings for I2S controller built into xtfpga Xtensa bitstreams.
Required properties:
- compatible: shall be "cdns,xtfpga-i2s".
- reg: memory region (address and length) with device registers.
- interrupts: interrupt for the device.
- clocks: phandle to the clk used as master clock. I2S bus clock
is derived from it.
Examples:
i2s0: xtfpga-i2s@0d080000 {
#sound-dai-cells = <0>;
compatible = "cdns,xtfpga-i2s";
reg = <0x0d080000 0x40>;
interrupts = <2 1>;
clocks = <&cdce706 4>;
};
