+CS42L52 audio CODEC
+
+Required properties:
+
+  - compatible : "cirrus,cs42l52"
+
+  - reg : the I2C address of the device for I2C
+
+Optional properties:
+
+  - reset_gpio : a GPIO spec for the reset pin.
+  - chgfreq    : Charge Pump Frequency values 0x00-0x0F
+  - mica_sel   : MIC A single ended input select MIC1/MIC2
+  - micb_sel   : MIC B single ended input select MIC1/MIC2
+  - mica_cfg   : MIC A single-ended or differential select
+  - micb_cfg   : MIC A single-ended or differential select
+  - micbias_lvl: Set the output voltage level on the MICBIAS Pin
+		 0x00 = 0.5 x VA
+		 0x01 = 0.6 x VA
+		 0x02 = 0.7 x VA
+		 0x03 = 0.8 x VA
+		 0x04 = 0.83 x VA
+		 0x05 = 0.91 x VA
+
+Example:
+
+codec: cs42l52 at 4a {
+	compatible = "cirrus,cs42l52";
+	reg = <0x4a>;
+	reset_gpio = <&gpio 10 0>;
