There are cases, where support for Type-C mux events is needed, that
does not have port partners.
Enabling communication to a retimer connected to an USB4 port, when
no devices are attached, is a case that requires support for handling
Type-C mux events without port partners.
The following patches[1] are needed on top of the mainline kernel to be
able to verify these patches.

configuration acknowledgment to EC")
