Hi Geert,
today, I want to learn some history ;)

Why do we read the extal* frequencies from DT and don't auto detect them
based on the MD pins?
Yesterday, I spent two hours debugging a clock issue due to a wrong DT
because the hardware guys populated a different EXTAL oscillator. I
would have saved this time if it would have been auto detected.
Best regards
