Hi linux-usb,
I'm currently bringing up a custom board that uses a CherryTrail
processor and I'm having quite a bit of trouble accessing the dual-role
port from Linux.
Our system includes two USB 3.0-capable ports with Type-C connectors.
One port is designed to be a host-only port (downstream-fac

I just finished backporting + testing your patch with our 4.14-kernel
(mine is already there) and it works great. The driver correctly
handles different EP06-configurations.
Thanks a lot
