I take your point on port as a signal but the way type-c determines 
data-role is via the DR_Swap message.

https://www.embedded.com/usb-type-c-and-power-delivery-101-power-delivery-protocol/

We receive an IRQ which is a packet containing DR_Swap - TCPM consumes 
that data and does a data-role switch.

The port then establishes the link between typec-port and redriver or PHY.

So, I think HS should be dropped from the commit logs and names in both 
series.

BTW for the GLINK devices I think the adsp firmware just notifies the 
APSS of the data-role switch so, these types of devices probably should 
have an epdoint with "usb_role_switch" in the name.
