We have validated only these. edp 2/3 corresponds to mdss1_dptx0 and mdss1_dptx1, and these are not validated, as already mentioned during the driver changes for the same. Should we mention the same in the commit message for the upcoming patchset ? > > > > > > > > > > > > + type = "full-size"; > > > > + > > > > + port { > > > > + dp0_connector_in: endpoint { > > > > + remote-endpoint = <&mdss0_dp0_out>; > > > > + }; > > > > + }; > > > > + }; > > > > + > > > > + dp1-connector { > > > > + compatible = "dp-connector"; > > > > + label = "DP1"; > > > > > > Same comment here. > > > > > > > + type = "full-size"; > > > > + > > > > + port { > > > > + dp1_connector_in: endpoint { > > > > + remote-endpoint = <&mdss0_dp1_out>; > > > > + }; > > > > + }; > > > > + }; > > > > }; > > > > > &apps_rsc { > > > >
