In linux kernel since version 2.6.20 (release Date: 2007-02-04)
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.
