* 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>;
};
