+Conexant CX20921/CX209724 Voice Processor DSP
+
+The devices supports both the I2C and SPI bus.
+
+Required properties:
+
+ - compatible: One of "cnxt,cx20921", "cnxt,cx20924".
+ - reg: The I2C address of the device for I2C, it should be <0x41>
+
+Optional properties:
+
+ - reset-gpios: A GPIO spec to define which pin is connected to the chip's
+ !RESET pin. If specified, the driver will assert a hardware
+ reset at probe time.
+
+CODEC input pins:
+ "MIC" - Microphone input
+
+Example:
+
+codec_i2c: cx20921@41 {
+ compatible = "cnxt,cx20921";
+ reg = <0x41>;
+ reset-gpios = <&gpio1 23 0>;
+};
+
+codec_spi: cx20924@0 {
+ compatible = "cnxt,cx20924";
+};
