40/*
41 History of this driver (Steven Toth):
42 I was given a public release of a linux driver that included
43 support for the MaxLinear MXL5005S silicon tuner. Analysis of
44 the tuner driver showed clearly three things.
45
46 1. The tuner driver didn't support the LinuxTV tuner API
47 so the code Realtek added had to be removed.
48
49 2. A significant amount of the driver is reference driver code
50 from MaxLinear, I felt it was important to identify and
51 preserve this.
52
53 3. New code has to be added to interface correctly with the
54 LinuxTV API, as a regular kernel module.
55
56 Other than the reference driver enum's, I've clearly marked
57 sections of the code and retained the copyright of the
58 respective owners.
