+/*
+ 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

+ 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

+
+ 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.
