373 RTC (Realtime Clock) driver for the clock inbuilt into the
374 Samsung S3C24XX series of SoCs. This can provide periodic
375 interrupt rates from 1Hz to 64Hz for user programs, and
376 wakeup from Alarm.
377
378 The driver currently supports the common features on all the
379 S3C24XX range, such as the S3C2410, S3C2412, S3C2413, S3C2440
380 and S3C2442.
