I've applied this to my devel branch. It's pretty huge but since it's split over three files I guess I can live with it. I can also see that you have really made an effort to cover the PXA variants and these drivers give a real good abstraction and understanding of this muxing hardware so WELL DONE!
I fixed a number of whitespace issues, so please base your further work upon my tree (once it emerges after the merge window).
I also removed the .maxpin on all pinctrl_desc:s, since that is gone now, we get the max pin from the pin list instead, so it's self-describing.
When I see things like this:
PINCTRL_PIN(GPIO0, "GPIO0"), PINCTRL_PIN(GPIO1, "GPIO1"), PINCTRL_PIN(GPIO2, "GPIO2"), PINCTRL_PIN(GPIO3, "GPIO3"), PINCTRL_PIN(GPIO4, "GPIO4"), PINCTRL_PIN(GPIO5, "GPIO5"),
I wish I could have loops in the preprocessor and just PINCTRL_PIN_RANGE("GPIO", start, end) but sadly I can't. So as mentioned earlier we might go for some static inline helper that can generate that array before you assign it to your pin controller.
Maybe the device tree is the answer to everything (as usual). Given the time it seems to take to find consensus around DT stuff we might just have to wait and see.
Yours, Linus Walleij
