I thought about much more basic things like "check if it's the right pin
name", "check if logic levels, fan in and fan out match", "check if the whole
idea is actually feasible" etc.
For this I have to scrutinize the corresponding sections in CPU datasheet, so
I understand what I'm asking for and what it should work like, instead of
just forwarding a "bake recipe" from ML. So some pointer would be welcome ;-)
Not eager to search the whole manual for "UEXTCLK"
