RT5665/RT5666 audio CODEC
|
|
This device supports I2C only.
|
|
Required properties:
|
|
- compatible : One of "realtek,rt5665", "realtek,rt5666".
|
|
- 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.
