1 * Atmel SAMA5D4 Watchdog Timer (WDT) Controller
4 - compatible: "atmel,sama5d4-wdt" or "microchip,sam9x60-wdt"
5 - reg: base physical address and length of memory mapped region.
8 - timeout-sec: watchdog timeout value (in seconds).
9 - interrupts: interrupt number to the CPU.
10 - atmel,watchdog-type: should be "hardware" or "software".
11 "hardware": enable watchdog fault reset. A watchdog fault triggers
13 "software": enable watchdog fault interrupt. A watchdog fault asserts
15 - atmel,idle-halt: present if you want to stop the watchdog when the CPU is
17 CAUTION: This property should be used with care, it actually makes the
18 watchdog not counting when the CPU is in idle state, therefore the
19 watchdog reset time depends on mean CPU usage and will not reset at all
20 if the CPU stop working while it is in idle state, which is probably
22 - atmel,dbg-halt: present if you want to stop the watchdog when the CPU is
