Sorry, my fault. You can definitely do this with any SoC that uses DT
for probing the PCI. I was merely assuming that you were asking about
ipq because the wifi chips and SoCs tend to come bundled from the
same manufacturer in embedded systems, and the MIPS based QCA SoCs
currently don't use DT.

For any machine that does not use DT, it would be much harder to
solve this problem though.
