A separate Kconfig option HAVE_S3C2410_WATCHDOG for Samsung SoCs is not really needed and the s3c24xx watchdog driver can depend on Samsung ARM architectures instead. The "HAVE_xxx_WATCHDOG" pattern of dependency is not popular and Samsung platforms are here exceptions. All others just depend on CONFIG_ARCH_xxx. This makes the code slightly smaller without any change in functionality. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> --- Changes since v1: 1. Re-add the dependency on architectures to keep same functionality.
Hi Guenter, Tomasz, Does such removal of HAVE_S3C2410_WATCHDOG makes sense for you? Best regards, Krzysztof
