The Linux kernel configuration item CONFIG_S3C2410_WATCHDOG
has multiple definitions:
drivers/watchdog/Kconfig
The configuration item CONFIG_S3C2410_WATCHDOG:
CONFIG_ARCH_S3C24XX || CONFIG_ARCH_S3C64XX || CONFIG_ARCH_S5PV210 || CONFIG_ARCH_EXYNOS || \
s3c2410_wdt
, s3c2410_wdt
Watchdog timer block in the Samsung SoCs. This will reboot the system when the timer expires with the watchdog enabled.
The driver is limited by the speed of the system's PCLK signal, so with reasonably fast systems (PCLK around 50-66MHz) then watchdog intervals of over approximately 20seconds are unavailable.
The driver can be built as a module by choosing M, and will be called s3c2410_wdt
drivers/char/watchdog/Kconfig
The configuration item CONFIG_S3C2410_WATCHDOG:
