Okay, I have the driver loaded:
root@orangepizero2w:/boot# dmesg | grep cedrus
[ 8.578154] sunxi_cedrus: module is from the staging directory, the quality is unknown, you have been warned.
[ 8.580382] cedrus 1c0e000.video-codec: Device registered as /dev/video2
I also did this:
root@orangepizero2w:/boot# v4l2-ctl --all --device /dev/video2
