SubjectRe: [PATCH v7 1/3] usb: typec: tcpci: move tcpci.h to include/linux/usb/ directory

The idea was to have tcpci compliant drivers in the tcpm/ subdirectory.
If I recall correctly, the reason for having this driver elsewhere is
that it doesn't support tcpm. That should be explained here.
"better for other USB Type-C driver" is not a reason for moving
a header file.

I don't think this should be part of the commit description.
