Any suggestions if and how it is possible to use a gpu/drm/panel MIPI = DSI video mode panel with omapdrm (on OMAP5)? The problem is that our old omapdrm/display driver is broken since v5.7 = and an experimental gpu/drm/panel driver does not probe. And I assume that omapdrm/display will disappear completely soon.
