Title: /dev/camsys_marvin & /dev/camsys_marvin1 on Ubuntu
Hi,

    I'm using Ubuntu and trying to read frames from two cameras (OV13850 board) connected to MIPI-CSI ports. From what I understand, it is not supported yet in Ubuntu.

    On the Android SDK, I see the two cameras are exposed as /dev/camsys_marvin and /dev/camsys_marvin1. The same marvin driver used in Android is also seen under Ubuntu Linux kernel source code.

    What I believe is missing in Ubuntu are the relevant DTS changes to enable the mipi-csi/isp/marvin. Android or Ubuntu, it is still Linux kernel and I belive bringing-up /dev/camsys_marvin and /dev/camsys_marvin1 on Ubuntu must be straight forward.

    Is my understanding correct? Could someone throw some light?


Thanks,
San
