If the child node doesn't have a compatible, how would the driver be
able to work
out the operational mode? The chip can only be in a single operational mode
at a time. So the child node has 'led' or 'regulator' compatible.

Or is there a more elegant method I've overlooked?

The chip contains a single optional regulator only. I documented its
dt bindings later in the patchset.
