RT5682 audio CODEC



This device supports I2C only.



Required properties:



- compatible : "realtek,rt5682" or "realtek,rt5682i"



- reg : The I2C address of the device.



Optional properties:



- interrupts : The CODEC's interrupt output.



- realtek,dmic1-data-pin

  0: dmic1 is not used

  1: using GPIO2 pin as dmic1 data pin

  2: using GPIO5 pin as dmic1 data pin



- realtek,dmic1-clk-pin

  0: using GPIO1 pin as dmic1 clock pin

  1: using GPIO3 pin as dmic1 clock 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 RT5682:



  * DMIC L1

  * DMIC R1

  * IN1P

  * HPOL

  * HPOR



Example:



rt5682 {

	compatible = "realtek,rt5682i";

	reg = <0x1a>;

	interrupt-parent = <&gpio>;

	interrupts = <TEGRA_GPIO(U, 6) GPIO_ACTIVE_HIGH>;

	realtek,ldo1-en-gpios =

		<&gpio TEGRA_GPIO(R, 2) GPIO_ACTIVE_HIGH>;

	realtek,dmic1-data-pin = <1>;

	realtek,dmic1-clk-pin = <1>;

	realtek,jd-src = <1>;

};
