Subject: [PATCH 8/8] ARM: dts: s5pv210: Fix infinite interrupt in soft mode
Date: Fri, 24 Feb 2017 17:11:22 +0200	[thread overview]
Message-ID: <20170224151122.12142-9-krzk@kernel.org> (raw)
In-Reply-To: <20170224151122.12142-1-krzk@kernel.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.
