However, what do we do with the 2 cases that exist in upstream that

are using ranges for cfg space?

Ignore them in the core code? Make the specific host controller handle
them I would think.

I just meant, should we ‘break’ their DTs and move them from using ranges to reg?

dw-pcie is used on a lot of systems, I think we should make the common
part of that driver always handle config space in a common way, and
move out the part that parses the ranges property into the individual
soc-specific glue drivers that want to keep optional backwards compatibility
with existing dtbs.

Which one is the other driver?

Its imx6 and exynos, havent looked to see if dw-pcie is handling the parsing or not for them.
