+Mikroe-PROTO audio board
+
+Required properties:
+ - compatible: "mikroe,mikroe-proto"
+ - dai-format: Must be "i2s".
+ - i2s-controller: The phandle of the I2S controller.
+ - audio-codec: The phandle of the WM8731 audio codec.
+Optional properties:
+ - model: The user-visible name of this sound complex.
+ - bitclock-master: Indicates dai-link bit clock master; for details see simple-card.txt (1).
+ - frame-master: Indicates dai-link frame master; for details see simple-card.txt (1).
+
+(1) : There must be the same master for both bit and frame clocks.
+
+Example:
+ sound {
+ compatible = "mikroe,mikroe-proto";
+ model = "wm8731 @ sama5d2_xplained";
+ i2s-controller = <&i2s0>;
+ audio-codec = <&wm8731>;
+ dai-format = "i2s";
