+* Cirrus Logic CLPS711X Digital Audio Interface (DAI)
+
+Required properties:
+- compatible: Should be "cirrus,clps711x-dai".
+- reg: Should contain registers location and length.
+- clocks: A clock specifier for the CPU PLL clock.
+- clock-names: The CPU PLL clock should be named "pll".
+- interrupts: Should contain DAI interrupt number.
+- syscon: phandle to syscon device node which control DAI (SYSCON3).
+
+Example:
+	dai: dai@80002000 {
+		#sound-dai-cells = <0>;
+		compatible = "cirrus,clps711x-dai";
+		reg = <0x80002000 0x604>;
+		clocks = <&clks 3>;
+		clock-names = "pll";
+		interrupts = <32>;
+		syscon = <&syscon3>;
+	};
