Florian, I'm really sorry for losing track of this patch set, it's important stuff and I see why systems are dependent on something like this.
Tony: can you look at this from a pinctrl-single point of view? This is the intended consumer: pinctrl-single users that lose the hardware state over suspend/resume.
How do you see this working with other pinctrl-single users?
Yours, Linus Walleij
