Why does not supported other than VERT_FLIP in ipuv3?

Hi

 

I have examined the rotation function on iMX6Q.

   echo 0 > /sys/class/graphics/fb0  :  0 degree.

   echo 1 > /sys/class/graphics/fb0  :  90 degree with mirror.

   echo 2 > /sys/class/graphics/fb0  :  0 degree.

   echo 3 > /sys/class/graphics/fb0  :  0 degree.

 

Then, I found following code from the mxcfb_check_var() in the mxc_ipuv3_fb.c

    if (var->rotate > IPU_ROTATE_VERT_FLIP)
         var->rotate = IPU_ROTATE_NONE;

 

[Question]

1. Why we can not use other rotate mode?

2. Is there any other ways to screen rotate?

 

Thanks,

Taro
