thanks for pointing this out.

After re-reading the binding and thinking about it again, I agree with you.
The proposed property describes a Linux driver policy (sysclk programming
order) rather than a hardware capability or configuration, so it does not
really fit the DT binding model.

I'll drop the DT binding part for now and reconsider how this should be
handled on the driver side instead.

If you have suggestions on a more appropriate direction for this kind of
configuration, I'd be happy to hear your opinion.

Best regards,
Stefano
