[Shah, Hardik] There is no need to change the nodes. If there is only one video device present than it should be /dev/video1 and not /dev/video2. Its upto the driver to use which video pipeline 1 or 2. So let the node nomenclature be same.

Thank you Shah, Hardik. I have patched your driver through that git. but your patch recognizes video2 layer as video1 device node in case that DSS2 has fb0 and fb1. you said my patch will give rise to couple of more bugs related to global_alpha and pixel formats maybe that would be because of vout->vid_info.id = k + vout_count;
