Some patchs was released, for i.MX6 IPU and rotating a frame buffer for kernel 3.10.17 and it was ok.
unfortunately, the new kernel version 4.1.15 is not compatible with the existings patchs.
I am try to adapt the existing patch for the 4.1.15 kernel version but it is too hard for me.
Please anybody can help me ?
May be a person can adapt the existing patch to obtain a rotoating frame buffer.
Thanks in advance
