There are no ABI implications just yet, we are free to change anything
we want.  It's all in drivers/staging/ now, where we will clean it up
some more over the next few weeks and then post reviewable sets of
patches to move portions out of staging (greybus core first, then some
class drivers, then the subsystem-specific things).  That will give you
your set of clean patches to review, and with the first rounds, no
device tree bindings at all :)
