-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
-
- - vdd-supply : A regulator node, providing 2.7V - 3.6V
-
-Optional properties:
-
- - reset-gpios : a GPIO spec for the reset pin. If specified, it will be
- deasserted before communication to the device starts.
-
-Example:
-
-spdif: ak4104@0 {
- compatible = "asahi-kasei,ak4104";
- reg = <0>;
- spi-max-frequency = <5000000>;
- vdd-supply = <&vdd_3v3_reg>;
-};
