Why? We enforce only generic names in shared schemas and this is neither
shared schema nor is it generic name.

Idea was to keep these node names consistent across DT files and parent node can allow a given list of child nodes with strict checks. Does name like "dynamic-range-compressor@xxx"

I would suggest generic node name, if it is possible.

May be "processing-engine@xxx" ?


peq@702d8100 {
Generic node name, so this is "equalizer", I guess?

Yes, I can use this name.
