Thanks for getting this started! It's unfortunately too late for 4.11 now,
but there should be no problem getting this merged into arm-soc early on
after the coming merge window.

I'd suggest keeping it as a set of patches for the moment, and we'll apply
them to the respective arm-soc branches as needed, with the exception of
the tty patch that should go through Greg's tree.

When you have addressed the review comments, please send the updated series
to arm-DgEjT+Ai2yi4UlQgPVntAg@public.gmane.org
