I would like to ask again if it may not be a better idea to introduce a 
fallback compatible, once this patchseries lands I will be adding the 
parade,ps185hdm. I don't know how many other variants there are that are 
just simple dp->hdmi bridges that don't require anything other than the 
connector type set to HDMIA. The Thinkbook 16 and zenbook a14 both have 
HDMI connectors, likely with simple bridges too.

Kind regards,
Maud
