I am using sdk 03.02 and trying to interface adv7180 with vip2 .I did the necessary modifications in device tree and able to register the device as /dev/video1 . I changed the v4l2 media bus format in vip to YUYV8_2X8 to register the device.When i see the properties of /dev/video1 using v4l2-ctl command i find  YUYV format but no width,height ,lsize information.what changes do i need to do so get the driver communicate with VIP.

    Hello,

    Please refer the below guide:
    software-dl.ti.com/.../Foundational_Components_Kernel_Drivers.html
    and make sure that you configure it correctly in the devicetree. Please check the debugging and Troubleshooting common capture problem chapters.
    It will be nice if you share the changes in the device tree that you have made.
    I would recommend you to check this txt file:
    video-interfaces.txt under <linux folder>/Documentation/devicetree/bindings/media and adv7180.txt .../devicetree/bindings/media/i2c
    Please check this thread: https://e2e.ti.com/support/processors/f/791/t/524349
    Hope this helps.
