I think Abhinaba captured all possible frequencies(even lowest ones) as
what the hardware currently describes. It's upto storage controller
running frequency and let it scale ice clocks to higher/lower to it's
max capabilities.

Describing hardware based information also avoid revisiting DTs at later
moment.
