>I'm also wondering why would adding a DT node for a PCI device be needed >in the first place, given that PCI supports device discovery? In fact, I learn that PCIe bus devices do not need compatible to probe just now... Before sending this patch, I committed the code that added "pci14e4,449d" to vendor-prefix.yaml and net/wireless/brcm,brcm4329-fmac.yaml. Now I know the reason why my addition was rejected. By the way, except for the compatible binding, is there any other binding that I should remove?? --- Best Regards Jacobe
