+* 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>;
+ };
