Another part of the problem is that it's a feature without in-tree
users -- there's not a single DT that defines the nodes (and thus can
be used to test it). Sure, there are no strict requirements to have
all bindings implemented on a platform but it sure does help catch
problems if you can test without applying out-of-tree patches to make
a feature work.

(I just merged the pull request from Sekhar, I had missed it before.
Should make -rc6).
