Sebastian, Linus, I've now created mvebu/pinctrl-dove for this series. It's based on v3.14-rc1, and depends on mvebu/pinctrl (which depends on mvebu/pinctrl-3xx). I've kept this series in a separate branch in case we encounter an unforeseen problem with something in here. Then this branch can be dropped, and /pinctrl-3xx and /pinctrl will still make it in. So, all patches except 3 and 4 are in mvebu/pinctrl-dove. 3 and 4 are in mvebu/dt. thx, Jason.
