trans-latency should really say what latency is being measured (the CPU
core only or the whole operation).

dts only descibe hw info. so the transition latency is for hw.
- trans-latency :  transition latency of HW, in unit of ns.

The issue is that you need to clarify which hardware this is - it's the
clocks only, not the time for regulators.

 - trans-latency :  transition latency of cpu freq and related regulator,
   in unit of ns.

Does it look better?
If you think regulator thansition latency is board specific, then the board
dts can overrite it.
