Just want to make sure before I send v2 of the whole series, this should be

        def_bool MACH_SUN8I
        select PINCTRL_SUNXI_COMMON

correct?

Or should it be

        bool
        depends on MACH_SUN8I
        select PINCTRL_SUNXI_COMMON

and MACH_SUN8I selects PINCTRL_SUN8I_A23

I'm not sure what the transition plan was.

[...]

v2 will also have EINT support.
