Hmm -- apologies if I pointed you in the wrong direction here on the
last revision (or should have considered this earlier), but is there a
particular need for this arrangement to be described by a single
regulator-output DT node instead of just having one node per supply? If
they're independently-controlled voltage outputs, treating them as two
separate things instead of a single ganged one seems like it might be
more appropriate anyway...
