Hello,
I am using a DSI display with a CM4 and a 5.15 Kernel. So far, I've been successful with a patched panel-simple.c and a custom devicetree overlay. Unfortunately, the native pixel addressing of the display leads to a portrait orientation (320 x 480) of the output. I added "rotation = <270>" to the panel overlay and it works for the CLI and boot logos. However, all graphical output (Raspbian Desktop, fbi, glmark2-es2-drm) is still shown in portrait mode. Can anyone please give me a pointer on how to rotate the graphical output properly? My cautious guess is that the rotation setting somehow isn't fully propagated to / implemented by the V3D driver. But hopefully, it's more trivial.
Here is some output for information:
