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

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>;
};
