2016-03-01watchdog: Add 'action' and 'data' parameters to restart handler callbackGuenter Roeck1-1/+2
The 'action' (or restart mode) and data parameters may be used by restart handlers, so they should be passed to the restart callback functions. Cc: Sylvain Lemieux <slemieux@tycoint.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

2015-09-09watchdog: mtk_wdt: add wdt shutdown callback to disable wdt if enabledGreta Zhang1-0/+9
Without .shutdown(), watchdog might reset the system during power off. For example, if watchdog's timeout is set to 30s, then it is reset to zero by mtk_wdt_ping(). During power off, no app will ping watchdog, but watchdog is still running and may trigger reset.

2015-03-27watchdog: mtk_wdt: signedness bug in mtk_wdt_start()Dan Carpenter1-1/+1
"ret" should be signed for the error handling to work correctly. This doesn't matter much in real life since mtk_wdt_set_timeout() always succeeds.
