Subject: [PATCH v3 1/2] dt-bindings: watchdog: Add Exynos8855 watchdog compatible string
Date: Tue, 6 Oct 2026 21:50:03 +0530 [thread overview]
Message-ID: <360067785.01791340382096.JavaMail.epsvc@epcpadp2new> (raw)
In-Reply-To: <CGME20261006160157epcas5p37b8a0053c489b051dfb415c9b72ba178@epcas5p3.samsung.com>
Add the 'samsung,exynos8855-wdt' compatible string to the Samsung
watchdog device tree binding documentation. The Exynos8855 watchdog
nodes use two clocks (bus clock and source clock), require
samsung,cluster-index and samsung,syscon-phandle properties, similar
to Exynos850 watchdog implementation.
