I'd expect a single property with freq/volt pairs or 2 properties for

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.
Multiple rails for single clock or would it be multiple clocks?
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.
But then how will you determine the operating voltage for a frequency?
