1Xilinx AXI/PLB soft-core watchdog Device Tree Bindings 2--------------------------------------------------------- 3 4Required properties: 5- compatible : Should be "xlnx,xps-timebase-wdt-1.00.a" or 6 "xlnx,xps-timebase-wdt-1.01.a". 7- reg : Physical base address and size 8 9Optional properties: 10- clocks : Input clock specifier. Refer to common clock 11 bindings. 12- clock-frequency : Frequency of clock in Hz 13- xlnx,wdt-enable-once : 0 - Watchdog can be restarted 14 1 - Watchdog can be enabled just once 15- xlnx,wdt-interval : Watchdog timeout interval in 2^<val> clock cycles, 16 <val> is integer from 8 to 31. 17 18Example: 19axi-timebase-wdt@40100000 { 20 clock-frequency = <50000000>; 21 compatible = "xlnx,xps-timebase-wdt-1.00.a"; 22 clocks = <&clkc 15>; 23 reg = <0x40100000 0x10000>; 24 xlnx,wdt-enable-once = <0x0>; 25 xlnx,wdt-interval = <0x1b>; 26} ; 27
