+RT5514 audio CODEC
+
+This device supports both I2C and SPI.
+
+Required properties:
+
+- compatible : "realtek,rt5514".
+
+- reg : the I2C address of the device for I2C, the chip select
+        number for SPI.
+
+Optional properties:
+
+- clocks: The phandle of the master clock to the CODEC
+- clock-names: Should be "mclk"
+
+- interrupts: The interrupt number to the cpu. The interrupt specifier format
+	      depends on the interrupt controller.
+
+- realtek,dmic-init-delay-ms
+  Set the DMIC initial delay (ms) to wait it ready for I2C.
+
+Pins on the device (for linking into audio routes) for I2C:
+
+  * DMIC1L
+  * DMIC1R
+  * DMIC2L
+  * DMIC2R
+  * AMICL
+  * AMICR
+
+Example:
+
+rt5514: codec@57 {
+	compatible = "realtek,rt5514";
+	reg = <0x57>;
+};
