imx8mp PCIE EP

[qwerqq]

I am currently using version 5.4.70 of imx8mp, and now I am using PCIE on two development boards. One does RC, the other does EP mode, now I can detect the device, the printing information is as follows:

root@OK8MP:~# lspci

00:00.0 PCI bridge: Synopsys, Inc. DWC_usb3 (rev 01)

01:00.0 Non-VGA unclassified device: Synopsys, Inc. DWC_usb3 (rev 01)

I now recognize the device, but I did not generate the corresponding device node in the /dev/directory because I still lack the corresponding device driver?Looking forward to your reply

Also, if the EP end is detected, will a node be generated under /dev/?
