Kernel Freeze while probing pci-imx6 driver

Hello,

 

We are trying to bring-up PCIe as Root-Complex only on imx8qxp chip. We are using Kernel version linux-imx-4.14.62

 

The issue we are facing now, is that the Kernel freezes while probing the pci-imx6 driver. After debugging, we found that it does not come back from any call to readl() or writel() function from the context of probe() function while trying to read any register from the configuration space of the host controller.

 

Can you point out what should we suspect? What could be the reason for this freeze?
