pinctrl/samsung: don't allow enabling pinctrl-samsung standalone
The main samsung pinctrl module references the specific exynos4210 pinctrl driver, which selects the main driver in Kconfig. Making the main driver a silent "bool" option avoid this potential build error if CONFIG_PINCTRL_SAMSUNG=y && CONFIG_PINCTRL_EXYNOS4=n: drivers/built-in.o:(.rodata+0x4e4): undefined reference to `exynos4210_pin_ctrl' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Tomasz Figa <t.figa@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: Linus Walleij <linus.walleij@linaro.org> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
