As you can imagine I am fine with the binding, so I can add my acked-by
once you send a non-RFC version.

The only thing I never understood is what's so special about GPIOs that
they have to bypass the pinctrl framework and instead a gpio_request
magically translates a gpio into a pin. Wouldn't it make sense to at
least add the pins in their GPIO mode to
arch/arm/boot/dts/sama5d2-pinfunc.h?
