Nuvoton NAU88L21 audio codec
|
||||
|
||||
This device supports I2C only.
|
||||
|
||||
Required properties:
|
||||
- compatible : Must be "nuvoton,nau8821"
|
||||
|
||||
- reg : the I2C address of the device. This is either 0x1B (CSB=0) or 0x54 (CSB=1).
|
||||
|
||||
Optional properties:
|
||||
- nuvoton,jkdet-enable: Enable jack detection via JKDET pin.
|
||||
- nuvoton,jkdet-pull-enable: Enable JKDET pin pull. If set - pin pull enabled,
|
||||
otherwise pin in high impedance state.
|
||||
- nuvoton,jkdet-pull-up: Pull-up JKDET pin. If set then JKDET pin is pull up, otherwise pull down.
|
||||
- nuvoton,jkdet-polarity: JKDET pin polarity. 0 - active high, 1 - active low.
|
||||
|
||||
- nuvoton,vref-impedance: VREF Impedance selection
|
||||
0 - Open
|
||||
1 - 25 kOhm
|
||||
2 - 125 kOhm
|
||||
3 - 2.5 kOhm
|
||||
|
||||
- nuvoton,micbias-voltage: Micbias voltage level.
|
||||
0 - VDDA
|
||||
1 - VDDA
|
||||
2 - VDDA * 1.1
|
||||
3 - VDDA * 1.2
|
||||
4 - VDDA * 1.3
|
||||
5 - VDDA * 1.4
|
||||
6 - VDDA * 1.53
|
||||
7 - VDDA * 1.53
|
||||
|
||||
- nuvoton,jack-insert-debounce: number from 0 to 7 that sets debounce time to 2^(n+2) ms
|
||||
- nuvoton,jack-eject-debounce: number from 0 to 7 that sets debounce time to 2^(n+2) ms
|
||||
|
||||
- nuvoton,dmic-clk-threshold: the ADC threshold of DMIC clock.
|
||||
- nuvoton,key_enable: Headset button detection switch.
|
||||
|
||||

|
||||
|
||||
headset: nau8821@1b {
|
||||
compatible = "nuvoton,nau8821";
