And as there is no edid for the connector, don't think call drm_connector_update_edid_property is required.
count = drm_add_modes_noedid(connector, 1920, 1200);Hi Tao, maybe it's better like this: count = drm_add_modes_noedid( connector , conn->dev->mode_config.max_width, conn->dev->mode_config.max_height);
drm_set_preferred_mode(connector, 1024, 768);return count;}
