- 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.

- interrupts = <TEGRA_GPIO(W, 3) GPIO_ACTIVE_HIGH>;
- realtek,ldo1-en-gpios =
- <&gpio TEGRA_GPIO(V, 3) GPIO_ACTIVE_HIGH>;
- };
