That's a hefty cc list. I can't see Rob Herring though, and he's
usually the person who you need to convince to get your bindings
accepted.
I recommend using ./scripts/get_maintainers.pl to build your CC list,
and then add others you think are relevant.
I'm not sure what the guidelines are for generic bindings, so I'll
defer to Rob for this patch.
Cheers,
Joel
Thanks a lot for letting me know that. I'll do as you suggested.
