That would be great !

Camera sensor drivers are the other piece of the puzzle that is
required. Daniel is working on an ov5693 driver which can be found at
https://github.com/djrscally/media_tree/tree/ov5693-v2. It's nearing
completion too.

With those two pieces, we have support for the Microsoft Surface Go 2 in
libcamera, as well as a few other devices whose exact model escapes me
at this minute.
