[PATCHv2 3/11] RTC: Real-time clock module of DA9052 device driver
From: dd diasemi
Date: Tue Dec 21 2010 - 13:16:23 EST
RTC module for DA9052 PMIC device from Dialog Semiconductor.
Changes made since last submission:
. added missing lock and unlock protection
. added rtc alarm enable functionality
. driver now uses platform_set_drvdata().
. rtc time getters are now validating parameter
Linux Kernel Version: 2.6.34
