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>;
|
