+* 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 {

   The node names should be generic, i.e. "watchdog" in this case.

[...]

MBR, Sergei
