So if you think we can get the panel driver upstream without the pyra dts files I am happy to submit something for review. But I have to fix it first. Maybe Tomi can comment about ideas what structural changes have been done so that it got broken since v5.7-rc1. Then it becomes easier to fix for me. Maybe there was some rework in omapdrm/dss which needs some change in the driver. And what I would need to know before I start to write new code is if is possible to operate a video mipi dsi panel with driver from gpu/drm/panel together with omapdrm (v5.7 and later). If this is possible it should be quite easy to mix the old omapdrm/display driver code with e.g.: drivers/gpu/drm/panel/panel-orisetech-otm8009a.c BR and thanks, Nikolaus
