IOW, no warnings from simple-bus schema? To my knowledge, simple-bus allows only objects, except the few allowed properties (and reg is not allowed because it is bus, not a device). Nice coincidence with other patchset from Intel also claiming FPGA with resources is the bus, although there it could be root port. Best regards, Krzysztof
