The "What:" field at the ABI should describe the location of the ABI, e. g. the position under a mounted sysfs. Fix it.

Description: Attribute for calibrating ST-Ericsson AB8500 Real Time Clock
|
|
The rtc_calibration attribute allows the userspace to
|
|
calibrate the AB8500.s 32KHz Real Time Clock.
|
|
Every 60 seconds the AB8500 will correct the RTC's value
|
|
by adding to it the value of this attribute.
|
|
The range of the attribute is -127 to +127 in units of
|
|
30.5 micro-seconds (half-parts-per-million of the 32KHz clock)
|
|
Users: The /vendor/st-ericsson/base_utilities/core/rtc_calibration

daemon uses this interface.
