1* Atmel SAMA5D4 Watchdog Timer (WDT) Controller
2
3Required properties:
4- compatible: "atmel,sama5d4-wdt" or "microchip,sam9x60-wdt"
5- reg: base physical address and length of memory mapped region.
6
7Optional properties:
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
12		    watchdog reset.
13	"software": enable watchdog fault interrupt. A watchdog fault asserts
14		    watchdog interrupt.
15- atmel,idle-halt: present if you want to stop the watchdog when the CPU is
16		   in idle state.
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
21	not what you want.
22- atmel,dbg-halt: present if you want to stop the watchdog when the CPU is
23		  in debug state.

25Example:
26	watchdog@fc068640 {
27		compatible = "atmel,sama5d4-wdt";
28		reg = <0xfc068640 0x10>;
29		interrupts = <4 IRQ_TYPE_LEVEL_HIGH 5>;
30		timeout-sec = <10>;
31		atmel,watchdog-type = "hardware";
32		atmel,dbg-halt;
33		atmel,idle-halt;
34	};
