2013-02-21rtc-pcf8523: add low battery voltage supportJesper Nilsson
Implement reading of the battery voltage low signal for rtc-pcf8523. The bit is read-only and cannot be cleared by software, so no clear function is implemented.

Add an RTC driver for PCF8523 chips by NXP Semiconductors. No support is currently provided for the alarm and interrupt functions. Only the time and date functionality is implemented.
