+CS53L30 audio CODEC
+
+Required properties:
+
+ - compatible : "cirrus,cs53l30"
+
+ - reg : the I2C address of the device
+
+ - VA-supply, VP-supply : power supplies for the device,
+ as covered in Documentation/devicetree/bindings/regulator/regulator.txt.
+
+Optional properties:
+
+ - reset-gpios : a GPIO spec for the reset pin.
+
+ - mute-gpios : a GPIO spec for the MUTE pin. The active state can be either
+ GPIO_ACTIVE_HIGH or GPIO_ACTIVE_LOW, which would be handled
+ by the driver automatically.
+
+ - cirrus,micbias-lvl : Set the output voltage level on the MICBIAS Pin.
+ 0 = Hi-Z
+ 1 = 1.80 V
+ 2 = 2.75 V
+
+ - cirrus,use-sdout2 : This is a boolean property. If present, it indicates
+ the hardware design connects both SDOUT1 and SDOUT2
+ pins to output data. Otherwise, it indicates that
+ only SDOUT1 is connected for data output.
+ * CS53l30 supports 4-channel data output in the same
+ * frame using two different ways:
+ * 1) Normal I2S mode on two data pins -- each SDOUT
+ * carries 2-channel data in the same time.
+ * 2) TDM mode on one signle data pin -- SDOUT1 carries
+ * 4-channel data per frame.
+
+Example:
+
+codec: cs53l30@48 {
+ compatible = "cirrus,cs53l30";
+ reg = <0x48>;
+ reset-gpios = <&gpio 54 0>;
+ VA-supply = <&cs53l30_va>;
+ VP-supply = <&cs53l30_vp>;
+};
