This bug is rather old so I'd like to summarize where we are now:

- there are i2c, iio and spi interfaces in snapd
- there is no uio interface yet

Interfaces must be defined by the gadget but we now have support for hot-plug detection that could be used instead of static declaration.

I'm not familiar with uio devices, can you share some information about development boards that have them? I found updated reference to the kernel documentation here https://www.kernel.org/doc/html/v4.17/driver-api/uio-howto.html but none of the reference platforms for snapd seems to have those.
