i.mx6 IPU rotate 180 degree

Hi all,

Is the i.mx6 IPU able to do 180 degree rotation in kernel?

In drivers/video/mxc/mxc_ipuv3_fb.c, I saw that there are two lines as below:

     if(var->rotate > IPU_ROTATE_VERT_FLIP)

          var->rotate = IPU_ROTATE_NONE;

 

Does it means the IPU only can do vertical flip? why is these two lines in the coding?

I am using kernel version 3.0.101.

 

Regards,

Tee
