Cirrus Logic CS4341 audio DAC
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>;
};
