Shouldn't sound-dai be required?
Sorry. I didn't get your Query. You mean in below "required:" properties need to add sound-dai also?

Shouldn't sound-dai be required? I don't know but maybe also additional
properties is false for this node too?

+
+ required:
+ - link-name
+ - cpu
+ - codec
Should 'reg' be required?
Okay. I think reg is required. will check and update it.
