From b2102eb36e7909c779e46f66595fda75aa219f4c Mon Sep 17 00:00:00 2001 From: Lars Poeschel Date: Thu, 25 Jun 2015 12:21:51 +0200 Subject: watchdog: omap_wdt: early_enable module parameter Add a early_enable module parameter to the omap_wdt that starts the watchdog on module insertion. The default value is 0 which does not start the watchdog - which also does not change the behavior if the parameter is not given.
