Right, so taking these two paragraphs together - if you have an absent
ranges you are imagining that the mbus driver would write out a new
fully populated ranges to the DTB? That would be necessary to keep
of_address_translate working.
If so we are talking about exactly the same thing - the in memory DTB
would still have working address translation.
An absent ranges makes some sense from a spec perspective - however do we
have the kernel infrastructure to grow an in memory DTB node?
