I mentioned exactly this in my message to SpacemiT just now.

And yes, regardless of their answer, you're probably right.
It is *possible* that these resets must be de-asserted, so
it's safest to describe them.

Conor please if you disagree with this, please say so.
Otherwise I think I'll keep them in the next version

Thanks.
