+RT5660 audio CODEC
+
+This device supports I2C only.
+
+Required properties:
+
+- compatible : "realtek,rt5660".
+
+- reg : The I2C address of the device.
+
+Optional properties:
+
+- clocks: The phandle of the master clock to the CODEC
+- clock-names: Should be "mclk"
+
+- realtek,in1-differential
+- realtek,in3-differential
+ Boolean. Indicate MIC1/3 input are differential, rather than single-ended.
+
+- realtek,poweroff-in-suspend
+ Boolean. If the codec will be powered off in suspend, the resume should be
+ added delay time for waiting codec power ready.
+
+- realtek,dmic1-data-pin
+ 0: dmic1 is not used
+ 1: using GPIO2 pin as dmic1 data pin
+ 2: using IN1P pin as dmic1 data pin
+
+Pins on the device (for linking into audio routes) for RT5660:
+
+ * DMIC L1
+ * DMIC R1
+ * IN1P
+ * IN1N
+ * IN2P
+ * IN3P
+ * IN3N
+ * SPO
+ * LOUTL
+ * LOUTR
+
+Example:
+
+rt5660 {
+ compatible = "realtek,rt5660";
+ reg = <0x1c>;
+};
