> How is this h/w controlled? I'm guessing it's part of the timer? If so, you don't need this node. A single node can implement multiple functions.

It is associated with the timer because of the shared register set. Based on feedback from Krzysztof I need to create a child node for gxp-timer. I therefore will remove this file and move gxp-wdt to the hpe,gxp-timer.yaml as a child node.

Thank you for the feedback.
