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.
