    Hi,

     

    VPIF driver in the Linux kernel is independent of the video chip connected. You should write your driver as a slave driver in V4L2 sub-dev framework and attach it to the VPIF driver. VPIF driver will call your video chip function when it is required.  Please go through the ths8200 driver to get the idea about how to write slave driver in sub-dev framework. Let me know if you need more information on this.

     

    Thanks,

    you mean I just modify the ths8200.c and ths8200.h?

    can you explain the details?

    I just want the 9134 to display in SD or HD.
