I see that 1/2 is already present in linux-next through commit 71d1f058844d.

At this time, I think the best way forward is to send 2/2 through my
tree. The only downside is if Linus merges ARM-SoC tree ahead of
watchdog tree, there will be a small period during merge window where
reset will be broken on DaVinci devices. I guess thats not such a big
issue (and I see no way around it except postponing 2/2 to v4.17).

I will be sending a pull request for 2/2 to ARM-SoC shortly and will
copy folks from this thread too.

Thanks,
Sekhar
