[Letux-kernel] framebuffer rotation

[H. Nikolaus Schaller]

Hi,
I just learned that

root at letux:~# echo 0 > /sys/class/graphics/fbcon/rotate_all 
root at letux:~# echo 1 > /sys/class/graphics/fbcon/rotate_all 
root at letux:~# echo 2 > /sys/class/graphics/fbcon/rotate_all 
root at letux:~# echo 3 > /sys/class/graphics/fbcon/rotate_all 

also does screen/framebuffer rotation.

Now I wonder why we need to patch drm_fb_helper (which is
currently broken in letux-5.3) and have our own ./tiler-ctl
script?

Any suggestions or explanations are welcome.

BR and thanks,
Nikolaus
