RT5640 audio CODEC
This device supports I2C only.
Required properties:
- compatible : "realtek,rt5640".
- 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.
Pins on the device (for linking into audio routes):
* DMIC1
* DMIC2
* MICBIAS1
* IN1P
* IN1R
* IN2P
* IN2R
* HPOL
* HPOR
* LOUTL
* LOUTR
* MONOP
* MONON
* SPOLP
* SPOLN
* SPORP
* SPORN
Example:
rt5640 {
compatible = "realtek,rt5640";
reg = <0x1c>;
interrupt-parent = <&gpio>;
interrupts = <TEGRA_GPIO(W, 3) GPIO_ACTIVE_HIGH>;
realtek,ldo1-en-gpios =
<&gpio TEGRA_GPIO(V, 3) GPIO_ACTIVE_HIGH>;
};
