-/*
- 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.
