| 2 | |
| 3 | The deadman timer is used to reset the processor in the event of a software |
| 4 | malfunction. It is a free-running instruction fetch timer, which is clocked |
| 5 | whenever an instruction fetch occurs until a count match occurs. |
| 6 | |
| 7 | Required properties: |
| 8 | - compatible: must be "microchip,pic32mzda-dmt". |
| 9 | - reg: physical base address of the controller and length of memory mapped |
| 10 | region. |
| 11 | - clocks: phandle of source clk. Should be <&rootclk PB7CLK>. |
| 12 | |
| 13 | Example: |
| 14 | |
| 15 | watchdog@1f800a00 { |
| 16 | compatible = "microchip,pic32mzda-dmt"; |
| 17 | reg = <0x1f800a00 0x80>; |
| 18 | clocks = <&rootclk PB7CLK>; |
| 19 | }; |
