[PATCH v2 1/3] dt-bindings: rtc: add reset-source property

2020-12-11 Thread Rasmus Villemoes
Some RTCs, e.g. the pcf2127, can be used as a hardware watchdog. But if the reset pin is not actually wired up, the driver exposes a watchdog device that doesn't actually work. Provide a standard binding that can be used to indicate that a given RTC can perform a reset of the machine, similar to
