Philipp has been working on one for quite some time. See
http://www.spinics.net/lists/arm-kernel/msg321927.html

However, it seems to progress slowly, and we don't seem to be able to
reach a consensus here.

If you ask me, having to set a few extra properties like this just
advocates for a regular reset driver and DT node for the reset GPIO,
but I'm pretty sure Philipp will feel otherwise :)
