Thank you for your patch. There is something to discuss/improve.

Drop "(default)"

You wrote that default is 0

You miss nuvoton,key_enable. If this is intentional, mention and shortly
explain deviations from pure conversion in the commit msg.

compatible is first property, reg is second. Therefore put
sound-dai-cells somewhere further.

-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

-      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.
