+/*
+ 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.
