From: Ville Syrjälä <[email protected]> Remove the lspcon special case from intel_dp_compute_config() and just treat it like any other DFP than can do 4:4:4->4:2:0 conversion.
The only difference between the two codepaths was that the lspcon code tried to already halve port_clock. That was just total nonsense as we hadn't even computed the base port_clock at that time. All that stuff happens intel_dp_compute_link_config*() and it already takes care of the 4:2:0 clock reduction.
