+This device supports both I2C and SPI (configured with pin strapping
+on the board).
+
+Required properties:
+ - compatible: "cirrus,cs4341a"
+ - reg : the I2C address of the device for I2C, the chip select
+ number for SPI.
+
+For required properties on I2C-bus, please consult
+Documentation/devicetree/bindings/i2c/i2c.txt
+For required properties on SPI-bus, please consult
+Documentation/devicetree/bindings/spi/spi-bus.txt
+
+Example:
+ codec: cs4341@0 {
+ #sound-dai-cells = <0>;
+ compatible = "cirrus,cs4341a";
+ reg = <0>;
+ spi-max-frequency = <6000000>;
+ };
