If yes, then we can just keep the array of <t/min/max> > in the same order. And software should be able to correlate then? It's probably not *too* bad for small numbers of supplies but bindings that require that indexes into two different arrays match up (particularly with different step sizes as here) do have legibility issues - it's easy to miscount when reading things. > > device's node.

No power supplies or clocks are connected to an OPP, an OPP is a property of something else.
