The following errors can be observed in dmesg on some boards (e.g. SANTINO/SANTINO-LT):
[ 3.102655] /disp0: could not find display-timings node
[ 3.108037] /disp0: no timings specifiedIt looks like panel_dt_get_non_edid_modes() was made from
panel_simple_get_non_edid_modes() of drivers/gpu/drm/panel/panel-simple.c
but increasing number of found modes was omited.
panel-simple.c has this code:
283- if (mode) {
284- drm_mode_probed_add(connector, mode);
285: num = 1;
286- } else {So add the same assignment in panel-dt.c too.
