This fails as ‘struct intel_dp’ has no member named ‘base’. 
Tried some variants, but I am clueless.. :-/

This seems easier, parse_ddi_port() assigns an 'is_edp' variable with
is_edp = is_dp && (child->common.device_type & 
DEVICE_TYPE_INTERNAL_CONNECTOR);

Assuming that setting it would suffice for my port to be detected as 
eDPI tried to change it to something like:
is_edp = is_dp && child->common.dvo_port == DVO_PORT_DPC;
or
is_edp = is_dp && (port == PORT_C);

is_edp = is_dp && port_name(port) == "DP-3"

since it's the third DP, but no success.

I must admit I am a bit clueless, but the solution seems within 
grasp....


Thanks very much
