Test your code - you will see your binding is a no-op. Best regards, Krzysztof

But when I check the bindings that do required the compatible... So I will add it next time. --- Best Regards Jacobe

But there are not, because schema is not applied to this node at all. Look how Apple is doing this. I have doubts that your code works at all in the first place. If there is no compatible, how your platform device gets of_node? Best regards, Krzysztof

In file brcm_hw_ids.h and pcie.c has added Device ID and Vendor ID for bus to enumerate the device when board bootup, so I didn't add specific compatible in DTS. And by doing so, it can probe successfully. --- Best Regards Jacobe

And by doing so, it can probe successfully. I did not ask about probe()... that's quite obvious. How the device's of_node is assigned? Best regards, Krzysztof
