  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.
