Last time I investigated, csi is present in mainline, but does not support vfe_v4l2, which the existing gc2035 code relies on.  It is no small task to reverse engineer the driver code, so as to migrate it. The hardware datasheets provide the means, but the effort is enormous compared to replacing the gc2035 with ov56xx hardware, which is fully supported in mainline and legacy.  The driver code is probably something xunlong need to provide, but don't hold your breath.

It would be easier for you to get a compatible ov**** camera, they are cheap and the driver is in kernel mainline.

Add EXPERT="yes" parameter to compile.sh and you will be able to make WIP images & kernels.

Problem is solved.
1) I make Armbian5.20 image from source code ( https://github.com/igorpecovnik/lib/archive/v2016.09.tar.gz )
2) Write image to SD card
3) Boot from SD card
4) After initial initialization of system it is necessary to execute:
sudo apt-get update
sudo apt-get upgrade
sudo reboot
5) Boot orangepi and login
sudo modprobe gc2035
sudo modprobe vfe_v4l2
