The native timers IP block found on Tegra SoCs implements a watchdog timer that can be used to recover from system hangs. This series of patches adds support for watchdog timers available on Tegra186, Tegra194 and Tegra234 SOC's. To keep the history intact, I added Tegra234 driver change as separate. The original patchset is an old one authored by Thierry.
