-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.
-
-Example:
-
- headset: nau8821@1b {
- compatible = "nuvoton,nau8821";
- reg = <0x1b>;
- interrupt-parent = <&gpio>;
- interrupts = <23 IRQ_TYPE_LEVEL_LOW>;
- nuvoton,jkdet-enable;
- nuvoton,jkdet-pull-enable;
- nuvoton,jkdet-pull-up;
- nuvoton,jkdet-polarity = <GPIO_ACTIVE_LOW>;
- nuvoton,vref-impedance = <2>;
- nuvoton,micbias-voltage = <6>;
- nuvoton,jack-insert-debounce = <7>;
- nuvoton,jack-eject-debounce = <7>;
- nuvoton,dmic-clk-threshold = 3072000;
