+* 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:
+
+ watchdog2: dmt@1f800a00 {
+ compatible = "microchip,pic32mzda-dmt";
+ reg = <0x1f800a00 0x80>;
+ clocks = <&PBCLK7>;
+ };
