It is a single PCIe controller which can be configured to either RC mode or EP mode. Wouldn't it conflict with the device tree principles to have two device tree nodes for the same PCIe controller? And obviously the two modes cannot be used at the same time so we cannot have two drivers both probe on the same hardware. Regards, Leo
