Yes. I did request[1] an immutable branch with just the driver change
applied, but looks like the message was lost and the current driver
change is applied over many other watchdog changes.

The main reason I sent it out anyway is because this cleanup is a
dependency to move to common clock framework and I want to reduce those
to a minimum to have a good chance of migrating to it in v4.17.

If the watchdog driver change never makes it (very low chance), then I
can resend a revert for -rc2. If ARM-SoC is merged before watchdog, yes,
during a short while in merge window reboot will be broken. But I
figured its a risk worth taking to have a chance of getting this into v4.16.

If you have a "send these late" branch, it will be nice to put it in
there. If this is too much uncertainty, then okay, lets hold for v4.17.

Thanks,
Sekhar
