In patch #3, we add the pinctrl property of uart device for the Bananapi-F3 board. You can find the pinctrl docs of K1 here[1], and the original vendor's pinctrl dts data here[2]. Note, we rewrite this series as an independent pinctrl driver for K1 SoC, which means it does not use pinctrl-single driver as the model anymore, see the suggestion from Krzysztof at [3].
