 5Description:    Attribute for calibrating ST-Ericsson AB8500 Real Time Clock
 6		The rtc_calibration attribute allows the userspace to
 7                calibrate the AB8500.s 32KHz Real Time Clock.
 8                Every 60 seconds the AB8500 will correct the RTC's value
 9                by adding to it the value of this attribute.
10
11                The range of the attribute is -127 to +127 in units of
12                30.5 micro-seconds (half-parts-per-million of the 32KHz clock)
