I was referring to drivers for connectors, binding to the connectors DT nodes. 
We shouldn't duplicate handling of connector-related features (ddc-i2c-bus 
being the most important one) in every bridge driver, and we need to pave the 
way for bridges chained with other bridges instead of being connected directly 
to a connector.
