Please say more about this device. Features, link to datasheet, etc.
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

yes, I will.

When clock detection is enabled, it will detect whether MCLK

FS range is from 8kHz to 96kHz. And also needs to detect the ratio
MCLK_SRC/LRCK of 256, 400 or 500, and needs to detect the BCLK
to make sure data is present. There needs to be at least 8 BCLK
cycles per Frame Sync.
