18c2ecf20Sopenharmony_ci* Microchip PIC32 Deadman Timer 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciThe deadman timer is used to reset the processor in the event of a software 48c2ecf20Sopenharmony_cimalfunction. It is a free-running instruction fetch timer, which is clocked 58c2ecf20Sopenharmony_ciwhenever an instruction fetch occurs until a count match occurs. 68c2ecf20Sopenharmony_ci 78c2ecf20Sopenharmony_ciRequired properties: 88c2ecf20Sopenharmony_ci- compatible: must be "microchip,pic32mzda-dmt". 98c2ecf20Sopenharmony_ci- reg: physical base address of the controller and length of memory mapped 108c2ecf20Sopenharmony_ci region. 118c2ecf20Sopenharmony_ci- clocks: phandle of source clk. Should be <&rootclk PB7CLK>. 128c2ecf20Sopenharmony_ci 138c2ecf20Sopenharmony_ciExample: 148c2ecf20Sopenharmony_ci 158c2ecf20Sopenharmony_ci watchdog@1f800a00 { 168c2ecf20Sopenharmony_ci compatible = "microchip,pic32mzda-dmt"; 178c2ecf20Sopenharmony_ci reg = <0x1f800a00 0x80>; 188c2ecf20Sopenharmony_ci clocks = <&rootclk PB7CLK>; 198c2ecf20Sopenharmony_ci }; 20
