-* 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 source clk. Should be <&rootclk PB7CLK>.
-
-Example:
-
- watchdog@1f800a00 {
- compatible = "microchip,pic32mzda-dmt";
- reg = <0x1f800a00 0x80>;
- clocks = <&rootclk PB7CLK>;
- };
