Subject: [PATCH] [V2,1/1]USB: serial: option: add Foxconn T77W175 composition 0x901d
Date: Mon, 16 Aug 2021 11:54:04 +0800	[thread overview]
Message-ID: <20210816035404.4210-1-slark_xiao@163.com> (raw)

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

Only interface 0 is used:
jbd@jbd-ThinkPad-P1-Gen-4:~$ lsusb | grep 05c6
Bus 003 Device 010: ID 05c6:901d Qualcomm, Inc. Generic Mobile Broadband Adapter
jbd@jbd-ThinkPad-P1-Gen-4:~$ lsusb -t | grep "Dev 10"
    |__ Port 7: Dev 10, If 0, Class=Vendor Specific Class, Driver=option, 480M
