[PATCH 0/2] watchdog: rti: adjust initial ping for attach

[Tero Kristo]

Hi,

This series fixes attaching the RTI watchdog driver to an already
running timer; it can be started by boot loader for example. In this
case, we must read the current remaining timeout, and adjust the
min_hw_heartbeat based on that so that we don't attempt to either pet
the watchdog too early, or too late.

The reason for all this is because the K3 RTI watchdog runs in windowed
mode only, petting it either too early, or too late causes a watchdog
reset.
