Concerning my use cases, they fix the issue described in https://lore.kernel.org/all/20240221095137.616d2aaa@xxxxxxxxxxx/ But not the one described in https://lore.kernel.org/lkml/20240312151835.29ef62a0@xxxxxxxxxxx/ A link is still present between the i2c@600 and the PCI device. instead of the i2c@600 and the pci-ep-bus. Adding the patch clearing the FWNODE_FLAG_NOT_DEVICE in device_add() available at [1] on top of your patches fixes the link issue. With this additional patch applied, the link is present between the i2c@600 and the pci-ep-bus. [1] https://lore.kernel.org/lkml/20240220111044.133776-2-herve.codina@xxxxxxxxxxx/ Best regards, Hervé
