What happens if there's more than one supply that needs to be varied?

Each rail's dvfs-table will have OPP nodes defined for different
voltages and each OPP node contains frequency for all clocks
affecting that rail.

Right, but some systems have operating points which cover a combination
of voltages and frequencies in one operating point.  Your binding seems
to define operating points per supply with no tie in between supplies.

We had discussed this in previous replies and thought that it can be 
expressed in separate DT nodes, may be regulator.
