Nope, that was wrong as we loose auto-select on Exynos. Instead: - def_bool y if ARCH_EXYNOS - depends on !ARM64 + bool "Exynos multi core timer driver" if ARM + depends on ARCH_EXYNOS || COMPILE_TEST + default y if ARCH_EXYNOS
This way we avoid select (which is a reverse dependency for the driver), have it auto-selectable and compile tested on arm.
Best regards, Krzysztof
