RT5650/RT5645 audio CODEC
|
|
|
|
This device supports I2C only.
|
|
|
|
Required properties:
|
|
|
|
- compatible : One of "realtek,rt5645" or "realtek,rt5650".
|
|
|
|
- reg : The I2C address of the device.
|
|
|
|
- interrupts : The CODEC's interrupt output.
|
|
|
|
Optional properties:
|
|
|
|
- hp-detect-gpios:
|
|
a GPIO spec for the external headphone detect pin. If jd-mode = 0,
|
|
we will get the JD status by getting the value of hp-detect-gpios.
|
|
|
|
- realtek,in2-differential
|
|
Boolean. Indicate MIC2 input are differential, rather than single-ended.
|
|
|
|
- realtek,dmic1-data-pin
|
|
0: dmic1 is not used
|
|
1: using IN2P pin as dmic1 data pin
|
|
2: using GPIO6 pin as dmic1 data pin
|
|
3: using GPIO10 pin as dmic1 data pin
|
|
4: using GPIO12 pin as dmic1 data pin
|
|
|
|
- realtek,dmic2-data-pin
|
|
0: dmic2 is not used
|
|
1: using IN2N pin as dmic2 data pin
|
|
2: using GPIO5 pin as dmic2 data pin
|
|
3: using GPIO11 pin as dmic2 data pin
|
|
|
|
-- realtek,jd-mode : The JD mode of rt5645/rt5650
|
|
0 : rt5645/rt5650 JD function is not used
|
|
1 : Mode-0 (VDD=3.3V), two port jack detection
|
|
2 : Mode-1 (VDD=3.3V), one port jack detection
|
|
3 : Mode-2 (VDD=1.8V), one port jack detection
|
|
