RT5668B audio CODEC
|
||||
|
||||
This device supports I2C only.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : "realtek,rt5668b"
|
||||
|
||||
- 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 RT5668B:
|
||||
|
||||
* DMIC L1
|
||||
* DMIC R1
|
||||
* IN1P
|
||||
* HPOL
|
||||
* HPOR
|
||||
|
||||
Example:
|
||||
|
||||
rt5668 {
|
||||
compatible = "realtek,rt5668b";
|
||||
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>;
|
||||
};
