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...
