Nuvoton NAU8825 audio codec
|
||||
|
||||
This device supports I2C only.
|
||||
|
||||
Required properties:
|
||||
- compatible : Must be "nuvoton,nau8825"
|
||||
|
||||
- reg : the I2C address of the device. This is either 0x1a (CSB=0) or 0x1b (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,sar-threshold-num: Number of buttons supported
|
||||
- nuvoton,sar-threshold: Impedance threshold for each button. Array that contains up to 8 buttons configuration. SAR value is calculated as
|
||||
SAR = 255 * MICBIAS / SAR_VOLTAGE * R / (2000 + R)
|
||||
where MICBIAS is configured by 'nuvoton,micbias-voltage', SAR_VOLTAGE is configured by 'nuvoton,sar-voltage', R - button impedance.
|
||||
Refer datasheet section 10.2 for more information about threshold calculation.
|
||||
|
||||
- nuvoton,sar-hysteresis: Button impedance measurement hysteresis.
|
||||
|
||||
- nuvoton,sar-voltage: Reference voltage for button impedance measurement.
|
||||
0 - VDDA
|
||||
1 - VDDA
|
||||
2 - VDDA * 1.1
|
||||
3 - VDDA * 1.2
|
||||

|
||||
5 - VDDA * 1.4
|
||||
6 - VDDA * 1.53
|
||||
7 - VDDA * 1.53
|
||||
|
||||
- nuvoton,sar-compare-time: SAR compare time
|
||||
0 - 500 ns
|
||||
1 - 1 us
|
||||
2 - 2 us
|
||||
3 - 4 us
|
||||
|
||||
- nuvoton,sar-sampling-time: SAR sampling time
|
||||
0 - 2 us
|
||||
1 - 4 us
|
||||
2 - 8 us
|
||||
3 - 16 us
|
||||
|
||||
- nuvoton,short-key-debounce: Button short key press debounce time.
|
||||
0 - 30 ms
|
||||
1 - 50 ms
|
||||
2 - 100 ms
|
||||
3 - 30 ms
|
||||
|
||||
- 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
|
||||
|
||||
- clocks: list of phandle and clock specifier pairs according to common clock bindings for the
|
||||
clocks described in clock-names
|
||||
- clock-names: should include "mclk" for the MCLK master clock
|
||||
