Subject: [PATCH v2 1/2] dt-bindings: watchdog: mtk-wdt: Add reset-by-toprgu support
Date: Mon, 16 Jan 2023 18:53:04 +0800 [thread overview]
Message-ID: <20230116105305.31818-2-allen-kh.cheng@mediatek.com> (raw)
In-Reply-To: <20230116105305.31818-1-allen-kh.cheng@mediatek.com>
In some applications, the mtk-wdt requires the toprgu (TOP Reset
Generation Unit) to reset timer after system resets. Add optional
mediatek,reset-by-toprgu property to enable it.
