RT274 audio CODEC
This device supports I2C only.
Required properties:
- compatible : "realtek,rt274".
- reg : The I2C address of the device.
Optional properties:
- interrupts : The CODEC's interrupt output.
Pins on the device (for linking into audio routes) for RT274:
* DMIC1 Pin
* DMIC2 Pin
* MIC
* LINE1
* LINE2
* HPO Pin
* SPDIF
* LINE3
Example:
codec: rt274@1c {
compatible = "realtek,rt274";
reg = <0x1c>;
interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
};
