[PATCH 1/2] dt-bindings: watchdog: mtk-wdt: Add reset-by-toprgu support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In some applications, the mtk-wdt requires the toprgu (TOP Reset
Generation Unit) to reset counter after wdt resets. Add optional
mediatek,reset-by-toprgu property to enable it.
