+Toshiba TX4927 Watchdog
+CONFIG_TX4927_WDT
+ This is a driver for the hardware watchdog integrated in the TX4927
+ microprocessor. If you want your processor to be reset when it becomes
+ unresponsive for a duration of time, say Y here, otherwise N.
+
+ This driver is also available as a module ( = code which can be
+ inserted in and removed from the running kernel whenever you want).
+ The module is called tx4927wdt.o. If you want to compile it as a
+ module, say M here and read <file:Documentation/modules.txt>. Most
+ people will say N.
+
+Heartbeat Multiplier
+CONFIG_TX4927_WDT_MULT
+ This is the multiplier used to calculate the next heartbeat duration.
+ In order to validate the responsiveness of the system, the system
+ must respond before the heartbeat runs out or the overflow counter
+ will be allowed to overflow. The next heartbeat time is set to the
+ overflow value * the multiplier.
+
+ If unsure, use the default value.
+
+Timer divisor
+CONFIG_TX4927_WDT_DIV
+ This is the divisor used to calculate the next time the overflow
+ counter is cleared. The timer is set to the overflow value / the
+ divisor.
+
+ If unsure, use the default value.
+
+Trigger NMI on overflow
+CONFIG_TX4927_WDT_NMI
+ This changes the behavior of the WDT upon an overflow. By default,
+ a reset is initiated at overflow time, but optionally this can be
+ disabled and an NMI can be triggered instead.
+
+ If unsure, say N.
+
+Overflow value (overrides default)
+CONFIG_TX4927_WDT_CMP
+ This changes the default overflow value. The watchdog overflows
+ when the overflow counter reaches this value. This can be any
+ 32-bit value (0 = use default), and defaults to 0xffffffff.
+
+ If unsure, use the default value.
