The Samsung pinctrl drivers depend on OF_GPIO, which is part of GPIOLIB. ARMv7 Exynos platform selects GPIOLIB and Samsung pinctrl drivers. ARMv8 Exynos selects only the latter leading to possible wrong configuration on ARMv8 build:
WARNING: unmet direct dependencies detected for PINCTRL_EXYNOS Depends on [n]: PINCTRL [=y] && OF_GPIO [=n] && (ARCH_EXYNOS [=y] || ARCH_S5PV210 || COMPILE_TEST [=y]) Selected by [y]: - ARCH_EXYNOS [=y]
