Foxconn SDX55 T77W175 device is working in PCIe mode normally.
You can find it in drivers/bus/mhi/pci_geneirc.c file.
But in some scenario, we need to capture the memory dump once it crashed.
So a diag port driver is needed.

Hi Sergei,
Yes, I didn't mix them up. Our product supports 3 modes: PCIE only, USB only, and PCIE+USB.
Normally, it would be PCIE mode. When we want to reproduce some crash issue, we will switch it from PCIE mode to PCIE+USB mode.
In this scenario, the USB port is used for capturing memory dump as our tool is designed based on Qualcomm USB Sahara protocol.
Thanks.

Why is this not sorted?
And the subject needs some work still...

Hi Greg,
Sorry, can you show me where should I put it at?
According to Bjørn comment, I think I need to create a new layout for Foxconn SDX55 device.
Thanks.

If it belongs in this list, then it should be in sorted order, which you
did not do here, so that would be a good idea, right?

That is up to you and Bjørn to work out :)

Hi Greg, Bjørn,
How about move this change to /drivers/usb/serial/option.c ? I just test it and everything is ok for my device.
And then we can ignore the layout issue.
Thanks
