		* Microchip PIC32 Deadman Timer

		The deadman timer is used to reset the processor in the event of a software
		malfunction. It is a free-running instruction fetch timer, which is clocked
		whenever an instruction fetch occurs until a count match occurs.

		Required properties:
		- compatible: must be "microchip,pic32mzda-dmt".
		- reg: physical base address of the controller and length of memory mapped
		region.
		- clocks: phandle of parent clock (should be &PBCLK7).

		Example:

		watchdog@1f800a00 {
		compatible = "microchip,pic32mzda-dmt";
		reg = <0x1f800a00 0x80>;
		clocks = <&PBCLK7>;
		};
