1*4882a593Smuzhiyun* Microchip PIC32 Deadman Timer 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunThe deadman timer is used to reset the processor in the event of a software 4*4882a593Smuzhiyunmalfunction. It is a free-running instruction fetch timer, which is clocked 5*4882a593Smuzhiyunwhenever an instruction fetch occurs until a count match occurs. 6*4882a593Smuzhiyun 7*4882a593SmuzhiyunRequired properties: 8*4882a593Smuzhiyun- compatible: must be "microchip,pic32mzda-dmt". 9*4882a593Smuzhiyun- reg: physical base address of the controller and length of memory mapped 10*4882a593Smuzhiyun region. 11*4882a593Smuzhiyun- clocks: phandle of source clk. Should be <&rootclk PB7CLK>. 12*4882a593Smuzhiyun 13*4882a593SmuzhiyunExample: 14*4882a593Smuzhiyun 15*4882a593Smuzhiyun watchdog@1f800a00 { 16*4882a593Smuzhiyun compatible = "microchip,pic32mzda-dmt"; 17*4882a593Smuzhiyun reg = <0x1f800a00 0x80>; 18*4882a593Smuzhiyun clocks = <&rootclk PB7CLK>; 19*4882a593Smuzhiyun }; 20
