From mboxrd@z Thu Jan 1 00:00:00 1970 From: krzk@kernel.org (Krzysztof Kozlowski) Date: Fri, 24 Feb 2017 17:11:20 +0200 Subject: [PATCH 6/8] ARM: dts: exynos: Fix infinite interrupt in soft mode on Exynos5440 In-Reply-To: <20170224151122.12142-1-krzk@kernel.org> References: <20170224151122.12142-1-krzk@kernel.org> Message-ID: <20170224151122.12142-7-krzk@kernel.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
