Seems like e.g. (most of) the sensor drivers are binary blobs.

Some examples:

Ambarella S3L: https://github.com/OpenIPC/firmware/tree/master/general/pack...

Some HiSilicon chipset: https://github.com/OpenIPC/firmware/tree/master/general/pack...

Edit: A smaller subset of sensors have some code here:
