Subject: [PATCH 3/3] ARM: dts: stm32: Add IWDG2 EXTI interrupt mapping and mark as wakeup source
Date:   Thu, 11 May 2023 02:19:49 +0200
Message-Id: <20230511001949.179521-3-marex@denx.de>
In-Reply-To: <20230511001949.179521-1-marex@denx.de>

The IWDG2 is capable of generating pre-timeout interrupt, which can be used
to wake the system up from suspend to mem. Add the EXTI interrupt mapping
and mark the IWDG2 as wake up source.
