1Technologic Systems Watchdog
2
3Required properties:
4- compatible: must be "technologic,ts4800-wdt"
5- syscon: phandle / integer array that points to the syscon node which
6          describes the FPGA's syscon registers.
7          - phandle to FPGA's syscon
8          - offset to the watchdog register
9
10Optional property:
11- timeout-sec: contains the watchdog timeout in seconds.
12
13Example:
14
15syscon: syscon@b0010000 {
16	compatible = "syscon", "simple-mfd";
17	reg = <0xb0010000 0x3d>;
18	reg-io-width = <2>;
19
20	wdt@e {
21		compatible = "technologic,ts4800-wdt";
22		syscon = <&syscon 0xe>;
23		timeout-sec = <10>;
24	};
25}
