1 Nuvoton NAU88L21 audio codec
3 This device supports I2C only.
6 - compatible : Must be "nuvoton,nau8821"
8 - reg : the I2C address of the device. This is either 0x1B (CSB=0) or 0x54 (CSB=1).
11 - nuvoton,jkdet-enable: Enable jack detection via JKDET pin.
12 - nuvoton,jkdet-pull-enable: Enable JKDET pin pull. If set - pin pull enabled,
13 otherwise pin in high impedance state.
14 - nuvoton,jkdet-pull-up: Pull-up JKDET pin. If set then JKDET pin is pull up, otherwise pull down.
15 - nuvoton,jkdet-polarity: JKDET pin polarity. 0 - active high, 1 - active low.
17 - nuvoton,vref-impedance: VREF Impedance selection
23 - nuvoton,micbias-voltage: Micbias voltage level.
33 - nuvoton,jack-insert-debounce: number from 0 to 7 that sets debounce time to 2^(n+2) ms
34 - nuvoton,jack-eject-debounce: number from 0 to 7 that sets debounce time to 2^(n+2) ms
36 - nuvoton,dmic-clk-threshold: the ADC threshold of DMIC clock.
