From ec90349a9433937e2fd83a57e16f40bce1fc1481 Mon Sep 17 00:00:00 2001 From: Marcus Folkesson Date: Wed, 26 Mar 2025 09:29:49 +0100 Subject: [PATCH] watchdog: da9052_wdt: use timeout value from external inputs Introduce the `timeout` module parameter and pass it to watchdog_init_timeout(). If the parameter is not set or contains an invalid value, fallback on the `timeout-secs` devicetree property value. If none of the above is valid, go for the old default value.
