Strictly speaking none of those components are passive: https:// en.wikipedia.org/wiki/Electronic_component#Passive_components. Only the VGA DACs based on resistor ladders (such as the one Maxime initially developed this driver for, see https://en.wikipedia.org/wiki/Resistor_ladder#R %E2%80%932R_resistor_ladder_network_(digital_to_analog_conversion)) can be considered passive devices. > config DRM_LVDS_ENCODER > tristate "Transparent parallel to LVDS encoder support" -- Regards, Laurent Pinchart _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
