/*
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.
