RT5651 audio CODEC
This device supports I2C only.
Required properties:
- compatible : "realtek,rt5651".
- reg : The I2C address of the device.
Optional properties:
- realtek,in2-differential
Boolean. Indicate MIC2 input are differential, rather than single-ended.
- realtek,dmic-en
Boolean. true if dmic is used.
Pins on the device (for linking into audio routes) for RT5651:
* DMIC L1
* DMIC R1
* IN1P
* IN2P
* IN2N
* IN3P
* HPOL
* HPOR
* LOUTL
* LOUTR
* PDML
* PDMR
Example:
codec: rt5651@1a {
compatible = "realtek,rt5651";
reg = <0x1a>;
realtek,dmic-en = "true";
realtek,in2-diff = "false";
};
