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
- realtek,in3-differential
Boolean. Indicate MIC1/2/3 input are differential, rather than single-ended.
- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
