Frambuffer rotation i.MX6

wesleyrevens — Wed, 22 Jun 2016 15:59:57 GMT

I have a TN LCD screen where the viewing angles are much improved if I turn the screen upside down.

Unfortunately, that means I also need to be able to rotate the graphics output by 180 degrees.

If I run "echo 3 > /sys/devices/soc0/fb.23/graphics/fb0/rotate" which should be an IPU_ROTATE_180

The image is not rotated.

The only time I get a change in the image on the screen is if I echo 1 > /sys/devices/soc0/fb.23/graphics/fb0/rotate

but that maps to IPU_VERT_FLIP so the image still looks incorrect on my screen.

Can anyone tell me how to get the IPU rotations >= 2 To work? I'm using kernel 3.14.38
