+RT5514 SPI audio CODEC
+
+This device supports SPI only.
+
+Required properties:
+
+- compatible : "realtek,rt5514".
+
+- reg : The SPI address of the device.
+
+Optional properties:
+
+- interrupt-parent: Should be the phandle for the interrupt controller
+- interrupts: The interrupt number to the cpu. The interrupt specifier format
+	      depends on the interrupt controller.
+
+Example:
+
+codec: rt5514-spi@0 {
+	compatible = "realtek,rt5514", "realtek,rt5514-spi";
+	reg = <0>;
+
+        /* May run faster once verified. */
+        spi-max-frequency = <10000000>;
+
+        pinctrl-names = "default";
+        pinctrl-0 = <&mic_int>;
+
+        interrupt-parent = <&gpio1>;
+        interrupts = <13 IRQ_TYPE_LEVEL_HIGH>;
+        wakeup-source;
