[PATCH v2 0/2] pinctrl: apple: Fixup and RFC GPIO mode patch

[Linus Walleij]

This fixes some uses of the "unsigned" type to "unsigned int"
then propose to implement the .function_is_gpio() callback.

The Apple pin control maintainers can comment on this: I
am not sure that "mode 0" is GPIO on this hardware but I
find it likely.

Toggling a pin between a certain function mode and GPIO
mode happens on any sufficiently advanced system sooner or
later and this callback was implemented because Qualcomm
ran into it, so let's add it to the Apple driver before
the users turn up.
