+CC Fengguang Wu, Dan Carpenter, Arnd Bergmann I used exynos_defconfig, and enabled socfpga mmc driver through menuconfig. Also, 'drivers/mmc/host/dw_mmc-socfpga.c' is used by ARCH_SOCFPGA. However, even though other configs are used, it should not make build error or link error. Please look at other drivers using MFD_SYSCON. i.mx config also selects MFD_SYSCON; however, it added MFD_SYSCON dependency in order to prevent link error.
