L6.1.22: iMX8MP PCIe not came up

[JefferyCheng]

kernel: linux-6.1.22

board: imx8mp-evk

It reports error:

I've tested linux-imx-5.15, it works fine. Can anyone fix linux-6.1 about the issue?  Thanks,

Hello @JefferyCheng ,

I hope you are doing well.

I have a few queries to ask, Please find them below.
-Have you used pre-built images or customized ones?
-If customized have you made any changes related to PCIe?
-If Yes please share these changes to debug them.

-Please make sure to check device tree configurations related to PCIe from the DOcumentation section. I have shared a location below.
If one wants to build the image and customized it on its own please refer to this document.

I hope it helps!

Thanks & Regards,
