From 7e93df3526b5dfc0ea76cb01041d7057f9fae478 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sat, 11 Mar 2017 19:25:25 +0200 Subject: [PATCH] ARM: dts: exynos: Fix infinite interrupt in soft mode on Exynos4210 and Exynos5440 In soft (no-reboot) mode, the driver self-pings watchdog upon expiration of an interrupt. The interrupt has to be cleared, because otherwise system enters infinite interrupt handling loop. Use a samsung,s3c6410-wdt compatible to select appropriate quirk for clearing the watchdog interrupt.
