PATCH 1/1 ARM: at91/dt: keep watchdog running in idle mode
Since turning on idle-halt in commit fe46aa679, SoCs compatible with the sam9 watchdog no longer reboot if the wdt times out. Removing the 'idle-halt' flag fixes this.

Since turning on idle-halt in commit
fe46aa679, SoCs compatible with the sam9 watchdog no longer reboot if the wdt times out. Removing the 'idle-halt' flag fixes this.
I missed that and I did exactly the same recently in my "[PATCHv2 0/2]
dts: AT91 Watchdog, remove property idle halt by default", first come, first serve:
But my patch summary is IMHO better (even with my broken english ;-).

I try to take it for at91-4.0-at91 and mix the 2 commit messages.
+ I take your documentation of the DT property.
Thanks, bye,
