Otherwise we would need to postpone the > new driver even further. As it came up a little bit late (the same day I sent pull request for 4.21), I was considering it as 4.22 material. But as you mentioned that the series is non-intrusive, I can try to send it to arm-soc folk for 4.21 merge window, and then that will be their call. But before I do it, I need you to double confirm that the series will not break anything that is already working.
