RT5665/RT5666/RT5668 audio CODEC



This device supports I2C only.



Required properties:



- compatible : One of "realtek,rt5665", "realtek,rt5666" or "realtek,rt5668".



- reg : The I2C address of the device.



- interrupts : The CODEC's interrupt output.



Optional properties:



- realtek,in1-differential

- realtek,in2-differential

- realtek,in3-differential

- realtek,in4-differential

  Boolean. Indicate MIC1/2/3/4 input are differential, rather than single-ended.



- realtek,dmic1-data-pin

  0: dmic1 is not used

  1: using GPIO4 pin as dmic1 data pin

  2: using IN2N pin as dmic2 data pin



- realtek,dmic2-data-pin

  0: dmic2 is not used

  1: using GPIO5 pin as dmic2 data pin

  2: using IN2P pin as dmic2 data pin



- realtek,jd-src

  0: No JD is used

  1: using JD1 as JD source



- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.



Pins on the device (for linking into audio routes) for RT5659/RT5658:



  * DMIC L1

  * DMIC R1

  * DMIC L2

  * DMIC R2

  * IN1P

  * IN1N

  * IN2P

  * IN2N

  * IN3P

  * IN3N

  * IN4P

  * IN4N

  * HPOL

  * HPOR

  * LOUTL

  * LOUTR

  * MONOOUT

  * PDML

  * PDMR



Example:



rt5659 {

	compatible = "realtek,rt5665";

	reg = <0x1b>;

	interrupt-parent = <&gpio>;

	interrupts = <TEGRA_GPIO(W, 3) GPIO_ACTIVE_HIGH>;

	realtek,ldo1-en-gpios =

		<&gpio TEGRA_GPIO(V, 3) GPIO_ACTIVE_HIGH>;

};
