This looks like your binding just describes a subset of the
watchdog timer registers. If so, don't do a standalone reset
driver, but instead do a watchdog driver that can also be
used for reset, and have a binding that properly describes
the watchdog hardware.
It is bad to have overlapping register ranges between logical
devices, and it's also generally wrong to describe devices that
are not actually there: The hardware contains a watchdog, not
a system-reset device, so you should not make one up because
it seems easier given the Linux driver model.
