This needs to model the uC connected to the UART rather than some node
that defines only some portion of the functionality. I'm working on
bindings and proper bus support for this[1], but it's not done yet.
Though, the binding side is pretty simple.

Actually I have limited knowledge on DT binding.
I think it should be OK to remove the 2/3 patch (this thread) in my

Thank you!

Cheers,
