- 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.
