RT5660 audio CODEC



This device supports I2C only.



Required properties:



- compatible : "realtek,rt5660".



- reg : The I2C address of the device.



Optional properties:



- clocks: The phandle of the master clock to the CODEC

- clock-names: Should be "mclk"



- realtek,in1-differential

- realtek,in3-differential

  Boolean. Indicate MIC1/3 input are differential, rather than single-ended.



- realtek,poweroff-in-suspend

  Boolean. If the codec will be powered off in suspend, the resume should be

  added delay time for waiting codec power ready.



- realtek,dmic1-data-pin

  0: dmic1 is not used

  1: using GPIO2 pin as dmic1 data pin

  2: using IN1P pin as dmic1 data pin



Pins on the device (for linking into audio routes) for RT5660:



  * DMIC L1

  * DMIC R1

  * IN1P

  * IN1N

  * IN2P

  * IN3P

  * IN3N

  * SPO

  * LOUTL

  * LOUTR



Example:



rt5660 {

	compatible = "realtek,rt5660";

	reg = <0x1c>;

};
