> After discussion with the devicetree maintainers we agreed to not extend
> lists with the generic compatible "apple,wdt" anymore [1]. Use
> "apple,t8103-wdt" as base compatible as it is the SoC driver and
> bindings were originally written for.
> The t602x (M2 Pro/Max/Ultra) devicetrees submitted in [2] use this
> compatible as fallback instead of "apple,wdt".
