Isn't this something that depend on the actual board design? From the driver
point of view you should not silently enforce such design requirement on the
board.
Am I missing something here? Would be glad to you if you can clarify in case.

[Richard Zhu] Yes, it is relied on the actual HW board design.
This regulator is one optional, not mandatory required for all the board designs.
So, there is one _enabled or not check before manipulate this regulator.

I think I was not clear in my question.

I'm asking what's is going to happen if the vpci-e supply is used in the
actual board design AND the same regulator is shared with another device (to my
understanding this should be just fine from the regulator API
point of view, correct me if I'm wrong).

I'm not talking about board designed by NXP in which such use case might not
exist.
