-Subject: [PATCH] watchdog: ath79-wdt: avoid spurious restarts on AR934x
-
-On some AR934x based systems, where the frequency of
-the AHB bus is relatively high, the built-in watchdog
-causes a spurious restart when it gets enabled.
-
-The possible cause of these restarts is that the timeout
-value written into the TIMER register does not reaches
-the hardware in time.
-
-Add an explicit delay into the ath79_wdt_enable function
-to avoid the spurious restarts.
