From a9e0436b303e94ba57d3bd4b1fcbeaa744b7ebeb Mon Sep 17 00:00:00 2001 From: gundberg Date: Thu, 24 Apr 2014 15:49:19 +0200 Subject: watchdog: kempld-wdt: Use the correct value when configuring the prescaler with the watchdog Use the prescaler index, rather than its value, to configure the watchdog. This will prevent a mismatch with the prescaler used to calculate the cycles.
