However, the fact that CONFIG_OF isn't enabled on x86 config > seems a bit complicated on this side. It does work, intel even used it for one of there tiny x86 SoCs. Maybe it was Newton? If you search around you can find maybe a Linux Plumbers presentation about DT and x86. You can probably use a udev rule, triggered by the PCIe device ID to load the DT overlay. Do you actually need anything from the host other than PCIe? It sounds like this card is pretty self contained, so you won't need phandles pointing to the host i2c bus, or the hosts GPIOs? You only need phandles to your own i2c bus, your own GPIOs? That will make the overlay much simpler. Andrew
