[PATCH v1 2/2] dt-bindings: watchdog: starfive,jh7100-wdt: Add compatible for JH8100

From: Ji Sheng Teoh
Date: Sat Dec 09 2023 - 09:28:09 EST


Add "starfive,jh8100-wdt" compatible string for StarFive's JH8100
watchdog.
Since JH8100 watchdog only has 1 reset signal, update binding
document to support one reset for "starfive,jh8100-wdt" compatible.
