Custom MIPI cameras

I would like to ask if there is a github project for the source of duo_camera_test_v0.2 binaries. I would like to extend the support to an AR2020 and an IMX* camera. I actually have the specs (register for camera rampup/clock setup…) to use and I’ve done the same for other 2 boards.

Is there any documentation available? I was not able to say if the i2c ramp up register are actually just in the binaries.
