Changing struct v4l2_if_type_bt656 for a csi2 format Help?

Hello ;

I need to modify the v4l2_if_type_bt656 parallel camera interface for csi2 interface I look at the this document http://electronix.ru/forum/index.php?act=Attach&type=post&id=67362

but I did not know where should I have to look at this document. Can some one explain what v4l2_if_type_bt656 struct is doing and how can I modify according to the csi2 interface. It would be very appreciated.

struct v4l2_if_type_bt656 {
   /*
   * 0: Frame begins when vsync is high.
   * 1: Frame begins when vsync changes from low to high.
   */
   unsigned frame_start_on_rising_vs:1;
   /* Use Bt synchronisation codes for sync correction. */
   unsigned bt_sync_correct:1;
   /* Swap every two adjacent image data elements. */
   unsigned swap:1;
   /* Inverted latch clock polarity from slave. */
   unsigned latch_clk_inv:1;
   /* Hs polarity. 0 is active high, 1 active low. */
   unsigned nobt_hs_inv:1;
   /* Vs polarity. 0 is active high, 1 active low. */
   unsigned nobt_vs_inv:1;
   enum v4l2_if_type_bt656_mode mode;
   /* Minimum accepted bus clock for slave (in Hz). */
   u32 clock_min;
   /* Maximum accepted bus clock for slave. */
   u32 clock_max;
   /*
   * Current wish of the slave. May only change in response to
   * ioctls that affect image capture.
   */
   u32 clock_curr;
};

Also I want to ask is ipu-v3.h compatible for csi2 interface which ipu specification should I use ?

Best Regards
