The code seems OK, but recently patches to add wdt-uclass has been
posted:

Maybe it would be better to port this driver to the uclass from
the
very beginning?

I started looking into this direction and have a question:
what the point to move to that class if it's broken from the
beginning?

I really do not understand who on the earth would like to have
wdt_stop() at ->probe() (the only two users do exactly that!).

At least for TI (omap), please find explanation in the description of this commit:

https://patchwork.ozlabs.org/patch/729819/


It's quite possible I'm just missing something, but I don't see
it.  If
the uclass is totally broken, can you make a suggestion on fixing it?

I need to think about it (I have an idea, though it requires time to
try).

  I
can see a common case being "lets turn off the watchdog now" and not
want a wdt until the full OS, but we must also fully support "U-Boot
has
and pets the Watchdog".

The users of WDT class now just disable watchdog. One of them, though,
is using it for reset (not my case for Tangier).

So, it looks to me now as bikeshedding, otherwise where is the
documentation which describes how this all stuff should work?

Can we go with the initial patch?

If it looks like some nightmare to fix the DM uclass, I suppose, but,
is
it really that bad off atm?

Not nightmare, but I really have not much time. Simon approached me
couple of weeks ago asking what is the status with my patches for
Tangier. That's why I found a slot to look at it.

So, I just have sent a v2 of this driver with old approach to move
things forward, otherwise I have no idea when it could be done.
