iMX8Q evaluation board PCIe boot failure

Right now we are working on iMX8 PCIe link. Without any PCIe device inserted in the iMX8Q evaluation board, we can get PCIe related message as below when boot up:


[    0.910397] 5f010000.pcie supply epdev_on not found, using dummy regulator
[    0.917200] OF: PCI: host bridge /pcie@0x5f010000 ranges:
[    0.922347] OF: PCI:   No bus range found for /pcie@0x5f010000, using [bus 00-ff]
[    1.187991] imx6q-pcie 5f010000.pcie: phy link never came up
[    1.193315] imx6q-pcie 5f010000.pcie: Link never came up
[    1.198622] imx6q-pcie 5f010000.pcie: failed to initialize host
[    1.204522] imx6q-pcie 5f010000.pcie: unable to add pcie port.
[    1.210580] imx6q-pcie: probe of 5f010000.pcie failed with error -110
It seems that iMX8Q still uses the same driver for PCIe from iMX6. Does any body can address what's the root cause?
Thanks a lot,
