/*
    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.
