+    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.

+   Basic firmware description. This will remain with
+   the driver for documentation purposes.
+
+   This represents an I2C firmware file encoded as a
+   string of unsigned char. Format is as follows:
+
+   char[0  ]=len0_MSB  -> len = len_MSB * 256 + len_LSB
+   char[1  ]=len0_LSB  -> length of first write transaction
+   char[2  ]=data0 -> first byte to be sent
+   char[3  ]=data1
+   char[4  ]=data2
+   char[   ]=...
+   char[M  ]=dataN  -> last byte to be sent
+   char[M+1]=len1_MSB  -> len = len_MSB * 256 + len_LSB
+   char[M+2]=len1_LSB  -> length of second write transaction
+   char[M+3]=data0
+   char[M+4]=data1
+   ...
+   etc.
+
+   The [len] value should be interpreted as follows:
+
+   len= len_MSB _ len_LSB
+   len=1111_1111_1111_1111   : End of I2C_SEQUENCE
+   len=0000_0000_0000_0000   : Reset command: Do hardware reset
+   len=0NNN_NNNN_NNNN_NNNN   : Normal transaction: number of bytes = {1:32767)
+   len=1WWW_WWWW_WWWW_WWWW   : Wait command: wait for {1:32767} ms
+
+   For the RESET and WAIT commands, the two following bytes will contain
+   immediately the length of the following transaction.

+   Basic firmware description. This will remain with
+   the driver for documentation purposes.
+
+   This represents an I2C firmware file encoded as a
+   string of unsigned char. Format is as follows:
+
+   char[0  ]=len0_MSB  -> len = len_MSB * 256 + len_LSB
+   char[1  ]=len0_LSB  -> length of first write transaction
+   char[2  ]=data0 -> first byte to be sent
+   char[3  ]=data1
+   char[4  ]=data2
+   char[   ]=...
+   char[M  ]=dataN  -> last byte to be sent
+   char[M+1]=len1_MSB  -> len = len_MSB * 256 + len_LSB
+   char[M+2]=len1_LSB  -> length of second write transaction
+   char[M+3]=data0
+   char[M+4]=data1
+   ...
+   etc.
+
+   The [len] value should be interpreted as follows:
+
+   len= len_MSB _ len_LSB
+   len=1111_1111_1111_1111   : End of I2C_SEQUENCE
+   len=0000_0000_0000_0000   : Reset command: Do hardware reset
+   len=0NNN_NNNN_NNNN_NNNN   : Normal transaction: number of bytes = {1:32767)
+   len=1WWW_WWWW_WWWW_WWWW   : Wait command: wait for {1:32767} ms
+
+   For the RESET and WAIT commands, the two following bytes will contain
+   immediately the length of the following transaction.
