+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@d080000 {
+ #sound-dai-cells = <0>;
+ compatible = "cdns,xtfpga-i2s";
+ reg = <0x0d080000 0x40>;
+ interrupts = <2 1>;
+ clocks = <&cdce706 4>;
+ };
