In linux kernel since version 4.14.326 (release Date: 2023-09-23)
Window watchdog driver for the versal_wwdt IP core.
Window watchdog timer(WWDT) contains closed(first) and
open(second) window with 32 bit width. Write to the watchdog
timer within predefined window periods of time. This means
a period that is not too soon and a period that is not too
late. The WWDT has to be restarted within the open window time.
If software tries to restart WWDT outside of the open window
time period, it generates a reset.
To compile this driver as a module, choose M here: the
module will be called xilinx_wwdt.
