From 723ec69a6b7eeb3e89d35dcf8fd223702ace6125 Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Mon, 30 Sep 2013 12:52:38 +0200 Subject: [PATCH] imx_watchdog: do not soft-reset while watchdog init Currently the driver clears WCR_SRS bit when enabling the watchdog and this causes a software reset. Do not clear WCR_SRS.
