Just for context: chat kind of consumers are these?

i.e. the consumers that can't tolerate a clock rate change?

I understand it if it is a hardware limitation (like the block would
crash if it glitches or changes rate).

On the other hand, in the kernel we have things like in
arch/arm/kernel/smp_twd.c we use a notifier to deal
with a changing clock rate.

Just want to be sure that you're not working around something that
can be dealt with using rate change notifiers.

(OK maybe a stupid question, I assume this is not the case, but anyways,
had to ask.)
