Subject: [PATCH] watchdog: kempld-wdt: Use the correct value when configuring the prescaler with the watchdog
Date: Thu, 24 Apr 2014 15:49:19 +0200 [thread overview]
Message-ID: <5359165F.5040102@icomera.com> (raw)
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.
