How to use V4l2 capture interface for two cameras

Hi All,

For our application we use two video streams from two different camera interfaces like below.

1. ADV7610 -> parallel CSI -> IPU

2. tw6869 -> pcie -> IPU

To support zero copying, both video streams are captured through imxv4l2videosrc of gstreamer. However I have only one v4l2cap node in dts file which is being utilized for parallel csi bus :

v4l2_cap_0 {
   compatible = "fsl,imx6q-v4l2-capture";
   ipu_id = <0>;
   csi_id = <0>;
   mclk_source = <0>;
   mipi_camera = <0>;
   default_input = <1>;
   status = "okay";
};

should I need two nodes to achieve simultaneous video streams ?

Thanks

Anuradha
