[PATCH 0/2] watchdog: dw_wdt: one bug fix and restart handler support

From: Jisheng Zhang
Date: Fri Sep 19 2014 - 02:32:59 EST


These patches are intend to improve dw_wdt in the following two aspects:

Firstly, the TOP_INIT may be zero at reset on some HW, so the timeout period
may be very short, thus we will see immediate system reset after openning
the watchdog. Fix this problem by restarting the counter immediately after
WDT enabling.

Secondly, the WDT can also be used to reboot the system with the help of
recently introduced restart handler.

Tested on Marvell BG2Q DMP board.
