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,
