+ This driver enables a watchdog capability built into the
+ CS5535/CS5536 companion chips for the AMD Geode GX and LX
+ processors. This watchdog watches your kernel to make sure
+ it doesn't freeze, and if it does, it reboots your computer after
+ a certain amount of time.
+
+ You can compile this driver directly into the kernel, or use
+ it as a module. The module will be called geodewdt.
