- 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.
- atmel,dbg-halt : Should be present if you want to stop the watchdog when
entering debug state.
