I strongly agree - the current proposal is very hard to read due to the
separation between the voltage and frequency values.  Some devices do
also need to scale multiple rails together, especially when this gets
used for I/O devices.

I'd also expect to see a range of voltages for each frequency rather
than a specific voltage; usually things are at least characterised with
a specified tolerance.
