	  Watchdog timer block in the Samsung SoCs. This will reboot

	  the system when the timer expires with the watchdog enabled.

	  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

	  be called s3c2410_wdt.
