RT5640/RT5639 audio CODEC
|
||
|
|
|
||
|
|
This device supports I2C only.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible : One of "realtek,rt5640" or "realtek,rt5639".
|
||
|
|
|
||
|
|
- reg : The I2C address of the device.
|
||
|
|
|
||
|
|
- interrupts : The CODEC's interrupt output.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
|
||
|
|
- realtek,in1-differential
|
||
|
|
- realtek,in2-differential
|
||
|
|
Boolean. Indicate MIC1/2 input are differential, rather than single-ended.
|
||
|
|
|
||
|
|
- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
