Hi Claudiu,

>         i2cset -y 1 0x18 0xf4 0x8 # Link down
>         i2cset -y 1 0x18 0xf4 0xc # Link up: PCIE_SLOT (NVMe Micron)

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.

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?

Thanks and happy hacking,

   Wolfram
