No expert available? Let me refine the question: By using the descriptions of panel-common.yaml and panel-timing.yaml it is possible to define a simple-panel by pure DTS means. This timing setup is done by code through: git blame drivers/gpu/drm/panel/panel-simple.c | grep of_get_display_timing 4a1d0dbc8332231 (Sam Ravnborg 2020-02-16 19:15:13 +0100 431) ret = of_get_display_timing(np, "panel-timing", timing); 4a1d0dbc8332231 (Sam Ravnborg 2020-02-16 19:15:13 +0100 566) if (!of_get_display_timing(dev->of_node, "panel-timing", &dt)) But it seems to lack a mechanism to define the connector type and bus format which is needed to make a panel finally work. Are we missing something or is the code/property missing? If it is the first, please let us know so that we can use it. If code is missing, please let us know so that we can suggest a patch.
