AK4104 S/PDIF transmitter
|
||||
|
||||
This device supports SPI mode only.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : "asahi-kasei,ak4104"
|
||||
|
||||
- reg : The chip select number on the SPI bus
|
||||
|
||||
Example:
|
||||
|
||||
spdif: ak4104@0 {
|
||||
compatible = "asahi-kasei,ak4104";
|
||||
reg = <0>;
|
||||
spi-max-frequency = <5000000>;
|
||||
};
