Patch 3 is the internal dt files we are using. 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?
