Would it make more sense to all this Nuvoton NPCM Timer? This way the

I notice the timer has a register in the middle of it that is used for
the watchdog. Should we describe this in the same binding? Even if we

This can probably be <0xf0008000 0x50>, as tthe timer hardware only
has registers up to base + 0x50.
