Hi Johan

As I'd already applied these I'd have preferred a fix patch and I'm not actually
sure it's really worth making the change.  I don't think we have any rules
about minimal includes or anything in DT bindings.  Was there an error or
warning as a result of this?

Still as I hadn't pushed out as non rebasing yet I've picked this version up
and dropped the previous.

Thanks,

Jonathan
