How about add a comment here:

Maybe add a warning here for parsing the legacy broken IORESOURCE_MEM
that's known to be broken from DT point of view?
Other than that, looks OK to me and should allow also changing to
use a generic solution, Mark may have some other comments.
Anyways, something like this is needed for v4.3-rc cycle, probably
best that Mark queues all these after review. So feel free to add
for the whole series:
