Hi Claudiu,

So, I applied your patches on current -next and did the above.
During LinkUp the card (Renesas USB3 host controller) got correctly
re-initialized. Same for physical unplug/plug.
Thank you for testing this series!
I don't know nothing about PCI, but I wondered about one thing: after
removal (both physically and via I2C), the card was still present in
/sys/bus/pci/devices. Is that expected?
I currently can't reproduce this on my side. Do you remember if you executed the below command before your test:
echo performance > /sys/module/pcie_aspm/parameters/policy
?
Thank you,
Claudiu
