[PATCH 5/7] ARM: samsung: Kill useless HAVE_S3C2410_WATCHDOG

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A separate Kconfig option HAVE_S3C2410_WATCHDOG for Samsung SoCs does
not have sense, because:
1. All ARMv7 and ARMv8 Samsung SoCs have watchdog,
2. All architecture Kconfigs were selecting it (if WATCHDOG framework is
   chosen),
3. HAVE_S3C2410_WATCHDOG is doing nothing except being a dependency of
   actual Samsung SoC watchdog driver, which is enabled manually by
   specific defconfigs.

HAVE_S3C2410_WATCHDOG can be safely removed.
