- * DS1286 Real Time Clock interface for Linux
- *
- * Copyright (C) 1998, 1999, 2000 Ralf Baechle
- *
- * Based on code written by Paul Gortmaker.
- *
- * This driver allows use of the real time clock (built into nearly all
- * computers) from user space. It exports the /dev/rtc interface supporting
- * various ioctl() and also the /proc/rtc pseudo-file for status
- * information.
- *
- * The ioctls can be used to set the interrupt behaviour and generation rate
- * from the RTC via IRQ 8. Then the /dev/rtc interface can be used to make
- * use of these timer interrupts, be they interval or alarm based.
- *
- * The /dev/rtc interface will block on reads until an interrupt has been
- * received. If a RTC interrupt has already happened, it will output an
- * unsigned long and then block. The output value contains the interrupt
- * status in the low byte and the number of interrupts since the last read
- * in the remaining high bytes. The /dev/rtc interface can also be used with
- * the select(2) call.
- *
