1* Microchip PIC32 Deadman Timer
2
3The deadman timer is used to reset the processor in the event of a software
4malfunction. It is a free-running instruction fetch timer, which is clocked
5whenever an instruction fetch occurs until a count match occurs.
6
7Required properties:
8- compatible: must be "microchip,pic32mzda-dmt".
9- reg: physical base address of the controller and length of memory mapped
10  region.
11- clocks: phandle of source clk. Should be <&rootclk PB7CLK>.

13Example:
14
15	watchdog@1f800a00 {
16		compatible = "microchip,pic32mzda-dmt";
17		reg = <0x1f800a00 0x80>;
18		clocks = <&rootclk PB7CLK>;
19	};
