+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;
+};
