Hi Paolo,

Thank you for your suggestions, which have been very helpful to us!

Currently, we are referring to the Rust implementation of sysbus to develop
the Rust version of I2CBus, and we have already made some phased progress.

Going forward, we will submit some RFC patches to the upstream for
everyone to discuss.

Thanks,
Chao
