Subject: [PATCH 2/3] dt-bindings: watchdog: fsl-imx7ulp-wdt: Add 'fsl,ext-reset-output'
Date: Tue, 10 Oct 2023 16:19:08 +0800 [thread overview]
Message-ID: <20231010081909.2899101-2-ping.bai@nxp.com> (raw)
In-Reply-To: <20231010081909.2899101-1-ping.bai@nxp.com>
The wdog may generate wdog_any external reset if the int_en bit is
configured, so add a property for this purpose in dt-binding doc.
