I also thought about it, as it has IMHO the cleaner code, and it would have the extra benefit that the gpt-wdt api doesn't need to be public.

However, the reasons I hesitated to do so are:
- I don't want to remove a file someone else wrote (even it doesn't work);
- WDT code is shifted from drivers/watchdog to arch/powerpc/platforms/52xx which might not be the "logical" place from the directory layout's pov;
- a file living in arch/powerpc/platforms/52xx depends upon config options set from drivers/watchdog/Kconfig which may be confusing.

You see these are more political/cosmetical questions, so I would prefer to leave the decision to the maintainers (i.e. you and Wim).  Preparing a fully merged driver is actually a matter of minutes!

Thanks,
Albrecht.
