     About i.MX5 TV-out application, all we can set in bootargs is,

           a. the "YUV444" to format DI

           b. the "TV-PAL/NTSC or others" to determine corresponding framebuffer's resolution & digital blanking

           c. the "tve" to fire TVE driver to work.


     as to i.MX6, we hope to mount a DA sinking from the DI(not MIPI,HDMI,LVDS...) in CCIR656 inferface, to achieve the CVBS-out we need.

     how to do ? we only trace something & set it, but no CCIR656 found on DI0/1 :

          i. mxcfb0:dev=lcd, TV-NTSC, if=YUV444

          ii. we add a named "TV-NTSC" in modedb, refer to the TVE setting in i.MX5


     please help me if any solution.
