General informations

The Linux kernel configuration item CONFIG_S3C2410_WATCHDOG has multiple definitions:

S3C2410 Watchdog found in drivers/char/watchdog/Kconfig

The configuration item CONFIG_S3C2410_WATCHDOG:

Help text

Watchdog timer block in the Samsung S3C2410 chips. 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
