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. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
