I think as well that we should avoid considering a regulator with
several outputs. I saw the same pattern used for the clock binding in DT
as well.

A clock node like a regulator node should output only one signal.
These nodes should provide atomic functionality. And if extra
functionality are needed we might consider adding some intermediate nodes.
Except for a regulator that will output several lines at the same
voltage to spread the current load, assuming it does exist, I'm not sure
to understand the need.

Mark,
What usage do you have in mind for such supply node with several outputs?
