Auvidea J100/J20 and RPi cameras

I’m trying to use Auvidea J20 on Jetson TX1 with the following tutorial, but don’t know where to get the “0003-add-j20-board-driver.patch”, is this patch used for kernel to support J20. BTW, I tried “sudo i2cdetect -r -y x” too, no i2c devices for PRi camera neither.

Can you tell me where to find “0003-add-j20-board-driver.patch” ?
