This would be an optimal place for a change log.

[ if any of my comments are duplicates, sorry, but a change log
   would help avoiding that ]


Sorry about that, I'll make sure to do so in the future.

The name and context make me wonder: Is this driver going to support
all watchdog devices for NI9[0-9]3[0-9] ?

If not, it may be better to select one supported device,
whatever that may be, for the name, and describe in Kconfig
and the documentation which devices the driver is known to support.


All of the 9[2-9]3[0-9] devices but the 963x do not and cannot run Linux,
so they won't be a problem. There is already a driver for the 963x watchdog in
our tree which is currently third in line for upstreaming, so that should be
fine as well. That would lead me to think 9x3x is fine, but if not then 903x is
fine.


Please use 903x, if you don't mind. After all, 9x3x _does_ include 963x
and is thus misleading.

Thanks,
Guenter
