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.
- realtek,btndet-delay
The debounce delay for push button.
The delay time is realtek,btndet-delay value multiple of 8.192 ms.
If absent, the default is 16.
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>;
realtek,btndet-delay = <16>;
};
