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>;

	};
