Help text

Watchdog timer block in the Samsung S3C24xx, S3C64xx, S5Pv210 and Exynos 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.

Choose Y/M here only if you build for such Samsung SoC. The driver can be built as a module by choosing M, and will be called s3c2410_wdt.
