Subject[PATCHv2 7/11] WATCHDOG: Re-organization of the SM driver as per the standard WDT available in Linux kernel
Date
From
Watchdog module of the device driver for DA9052 PMIC device from Dialog
Semiconductor.

Changes made since last submission:
. code has been reorganised as per the standard linux kernel driver
framework
. removal of redundant printk and comments
. removal of test framework

Linux Kernel Version: 2.6.34
