RT5651 audio CODEC
This device supports I2C only.
Required properties:
- compatible : "realtek,rt5651".
- reg : The I2C address of the device.
Optional properties:
- realtek,in2-differential
Boolean. Indicate MIC2 input are differential, rather than single-ended.
- realtek,dmic-en
Boolean. true if dmic is used.
- realtek,jack-detect-source
u32. Valid values:
1: Use JD1_1 pin for jack-detect
2: Use JD1_2 pin for jack-detect
3: Use JD2 pin for jack-detect
- realtek,over-current-threshold-microamp
u32, micbias over-current detection threshold in µA, valid values are
600, 1500 and 2000µA.
- realtek,over-current-scale-factor
u32, micbias over-current detection scale-factor, valid values are:
0: Scale current by 0.5
1: Scale current by 0.75
2: Scale current by 1.0
3: Scale current by 1.5
