The A23 uses the same pin controller as previous SoC's from Allwinner.
Add support for the pins controlled by the main PIO controller.

This last line belongs in the R_PIO patch :)

Since it's going to be merged in 3.16, you can just depend on MACH_SUN8I.

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.

The former.

v2 will also have EINT support.

Cool :)
