HI Sergei,
  Yes. Our produt has 3 mode: PCIe mode only, USB mode only, and PCIE+USB.
  When we need to reproduce some crash issue, we will let it enter into PCIE+USB mode.
  In this scenario, USB would have a diag port to capture memory dump.

That's all fine, I was just pointing out the typo. :-)
Couldn't open your another reply...

Foxconn SDX55 T77W175 device is working in PCIe mode normally.
You can find it in drivers/bus/mhi/pci_geneirc.c file.

pci_generic? :-)

But in some scenario, we need to capture the memory dump once it crashed.
So a diag port driver is needed.
