yes, there is something in our upstreaming pipeline. This one works for us on top of 4.4.0:

<http://git.goldelico.com/?p=gta04-kernel.git;a=shortlog;h=refs/heads/work/hns/misc/w2sg-tty-slave2-v4>

There is one point still to be solved: the exact style of the DT bindings.

We have an idea how a driver can implement two different styles (child node AND phandle)
so that it is up to the DTS developer to use the one that best fits into the existing DTS.

BR,
