Then the pci@0,0 is the child, so what is this? The host bridge is the parent of pcie@0,0. And pcie@0,0 is Bridge1, so the wifi@0,0 as a device under the Bridge1. > >> + reg = <0x410000 0 0 0 0>; >> + clocks = <&hym8563>; >> + clock-names = "32k"; > >1. Bindings are before the users. >2. Where is the compatible? Are you sure this validates? Before, the compatible is "pci14e4,449d", but when I checkpatch the warning said that "pci14e4" was not documented, so I remove the compatible which doesn't affect the Wi-Fi function. I have tried to add "pci14e4" to vendor-prefixes.yaml but was refused. So whether should I add the compatible with warning?
