[PATCH v3 3/7] dt-bindings: watchdog: convert meson-wdt.txt to dt-schema

There is a newer version of this series
[PATCH v3 3/7] dt-bindings: watchdog: convert meson-wdt.txt to dt-schema
Posted by Neil Armstrong 2 years, 7 months ago 
Convert the Amlogic Meson6 SoCs Watchdog timer bindings to dt-schema.

Take in account the used interrupts property.

The "amlogic,meson8-wdt" representation has been simplified
since there's no users of this compatible used along the
"amlogic,meson6-wdt".
