No, if you run it per file or per directory, prefix is the same. Starts with regulator, doesn't it?

regulator: dt-bindings: nxp,pca9450: add foo bar

Where do you see such syntax?

I don't understand what you want to express with such syntax. That's why I suggested you to look for existing examples. There is no such code as above, so you are the first one to add it. And then the obvious question: why are you doing things quite different than others? That's pretty often a hint that something is odd.

Again, what do you want to achieve?

No. What do you want to achieve?
