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.

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.
