Kernel-4.18.0-80.el8_microchip,pic32-dmt

• 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>;
};
