as NS16550-compatible UARTs, real-time clock, and timers.
The Elan SC520 also provides several special on-chip devices. The follow-
ing are supported by the elansc driver:
+ Watchdog timer. The watchdog timer may be configured for a 1 second,
2 second, 4 second, 8 second, 16 second, or 32 second expiration
period.
