+    History of this driver (Steven Toth):
+      I was given a public release of a linux driver that included
+      support for the MaxLinear MXL5005S silicon tuner. Analysis of
+      the tuner driver showed clearly three things.
+
+      1. The tuner driver didn't support the LinuxTV tuner API
+         so the code Realtek added had to be removed.
+
+      2. A significant amount of the driver is reference driver code
+         from MaxLinear, I felt it was important to identify and
+         preserve this.
+
+      3. New code has to be added to interface correctly with the
+         LinuxTV API, as a regular kernel module.
+
+      Other than the reference driver enum's, I've clearly marked
+      sections of the code and retained the copyright of the
+      respective owners.

+          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.
