+* Cirrus Logic CLPS711X Digital Audio Interface (DAI)
+
+Required properties:
+- compatible:  Shall contain "cirrus,clps711x-dai".
+- reg:         Should contain registers location and length.
+- clocks:      phandle + clock specifier pair of the CPU PLL reference
+               clock and (optionally) external MCLK reference clock.
+- clock-names: The clock should be named "pll" for CPU PLL and "mclk"
+               for external MCLK.
+- interrupts:  Should contain DAI interrupt number.
+
+Example:
+	dai: dai@80002000 {
+		#sound-dai-cells = <0>;
+		compatible = "cirrus,ep7312-dai", "cirrus,clps711x-dai";
+		reg = <0x80002000 0x604>;
+		clocks = <&clks 3>, <&clk12288>;
+		clock-names = "pll", "mclk";
+		interrupts = <32>;
+	};
