+ZTE zx96p22 controller
+
+Required properties:
+ - compatible : Must be "zte,zx-aud96p22"
+ - #sound-dai-cells: Should be 0
+ - reg : Offset of I2C register for zx96p22
+
+Example:
+
+	audio_i2c0: audio_i2c0@...6000 {
+		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>;
+		status = "ok";
+		inner_codec: aud96p22@22 {
+			compatible = "zte,zx-aud96p22";
+			#sound-dai-cells = <0>;
+			reg = <0x22>;
