Are the following revisions correct?
Add a DT schema for describing nau8325 audio amplifiers. The key
features are as follows:
- Low SPK_VDD Quiescent Current
- Gain Setting with 2-wire interface
- Powerful Stereo Class-D Amplifier
- Low Output Noise
- Low Current Shutdown Mode
- Click-and Pop Suppression

Is the description of the following modification correct?
nuvoton,vref-impedance:
$ref: /schemas/types.yaml#/definitions/uint32
description:
The vref impedance to be used in KOhms. Voltage Reference impedance
selection. VREF impedance selection.
enum:
- 0 # Disable tie off resistance
- 1 # 25KOhms
- 2 # 125KOhms
- 3 # 2.5kOhms
default: 2
