+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@4a {
+ compatible = "cirrus,cs42l52";
+ reg = <0x4a>;
+ reset_gpio = <&gpio 10 0>;
+ chgfreq = <0x05>;
+ mica_sel = <0x01>;
+ micbias_lvl = <0x05>;
