I tried now with kernel 6.6.20 and had no success so far. In fact, the dtoverlay and driver mentioned above do not rotate the output at all (neither text nor graphical). Only an additional KMS argument in cmdline.txt [1] rotates the splash box and text output after a few seconds (the first seconds during boot show still unrotated content) but all graphical output (Wayland, EGLFS, fbi) appears still unrotated. Of course, I can rotate the screen through the Wayfire configuration, but ideally, our single-app embedded system does not depend on a window manager. Any further ideas?
Again, here is some more information:
[1] video=DSI-1:320x480@60,rotate=90
