+ZTE ZX AUD96P22 Audio Codec
+
+Required properties:
+ - compatible: Must be "zte,zx-aud96p22"
+ - #sound-dai-cells: Should be 0
+ - reg: I2C bus slave address of AUD96P22
+
+Optional properties:
+ - zte,pa-gpios: The GPIO to enable external power amplifier
+
+Example:
+
+	i2c0: i2c at 1486000 {
+		compatible = "zte,zx296718-i2c";
+		reg = <0x01486000 0x1000>;
+		interrupts = <GIC_SPI 35 IRQ_TYPE_LEVEL_HIGH>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+		clocks = <&audiocrm AUDIO_I2C0_WCLK>;
+		clock-frequency = <1600000>;
+
+		aud96p22: codec at 22 {
+			compatible = "zte,zx-aud96p22";
+			#sound-dai-cells = <0>;
+			reg = <0x22>;
+			zte,pa-gpios = <&bgpio4 0 GPIO_ACTIVE_HIGH>;
+		};
