Subject: [PATCH 3/7] arm/arm64: dts: mediatek: drop mt6589 fallback from watchdog
Date: Fri, 17 Jul 2026 01:19:19 +0900 [thread overview]
Message-ID: <20260716161923.266315-4-akkun11.open@gmail.com> (raw)
In-Reply-To: <20260716161923.266315-1-akkun11.open@gmail.com>
Remove the "mediatek,mt6589-wdt" fallback string from all in-tree
device trees. Use only the SoC-specific compatible.
No functional change.
Affected SoCs: mt2701, mt6572, mt6582, mt6797, mt7622, mt7623,
mt7629, mt8173, mt8365, mt8516.
