This means that MediaTek SoCs can change their CPU frequency once every
10 milliseconds?!?!?!

I don't think that's really the case.

Besides, are you aware that this will have a *huge* impact on either power
consumption or performance?
We're going from a bunch of microseconds to *multiple* milliseconds here.
