|
||||
- atmel,disable : Should be present if you want to disable the watchdog.
|
||||
- atmel,idle-halt : Should be present if you want to stop the watchdog when
|

entering idle state.
|
||||
CAUTION: This property should be used with care, it actually makes the
|
||||
watchdog not counting when the CPU is in idle state, therefore the
|
||||
watchdog reset time depends on mean CPU usage and will not reset at all
|
||||
if the CPU stop working while it is in idle state, which is probably
|
||||
not what you want.
