|
||||
|
||||
This device supports I2C only.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : One of "realtek,rt5640" or "realtek,rt5639".
|
||||
|
||||
- reg : The I2C address of the device.
|
||||
|
||||
- interrupts : The CODEC's interrupt output.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- clocks: The phandle of the master clock to the CODEC
|
||||
- clock-names: Should be "mclk"
|
||||
|
||||
- realtek,in1-differential
|
||||
- realtek,in2-differential
|
||||
- realtek,in3-differential
|
||||
Boolean. Indicate MIC1/2/3 input are differential, rather than single-ended.
|
||||
|
||||
- realtek,lout-differential
|
||||
Boolean. Indicate LOUT output is differential, rather than stereo.
|
||||
|
||||
- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
|
||||
|
||||
- realtek,dmic1-data-pin
|

0: dmic1 is not used
|
||||
1: using IN1P pin as dmic1 data pin

|
||||
6: Use GPIO4 for jack-detect
|
||||
|
||||
- realtek,jack-detect-not-inverted
|
||||
bool. Normal jack-detect switches give an inverted signal, set this bool
|
||||
in the rare case you've a jack-detect switch which is not inverted.
