+==========================
+WatchDog Module Parameters
+==========================
+
+This file provides information on the module parameters of many of
+the Linux watchdog drivers. Watchdog driver parameter specs should
+be listed here unless the driver has its own driver-specific information
+file.
+
+See Documentation/admin-guide/kernel-parameters.rst for information on
+providing kernel parameters for builtin drivers versus loadable
+modules.
+
+-------------------------------------------------
+
+watchdog core:
+ open_timeout:
+ Maximum time, in seconds, for which the watchdog framework will take
+ care of pinging a running hardware watchdog until userspace opens the
+ corresponding /dev/watchdogN device. A value of 0 means an infinite
+ timeout. Setting this to a non-zero value can be useful to ensure that
+ either userspace comes up properly, or the board gets reset and allows
+ fallback logic in the bootloader to try something else.
