47cc5b7810 V4L/DVB (6631): xc2028: eliminate i2c macro side-effects
The I2C macros have side effects and send_seq could cause a return from
a function with a mutex held.  Change them to behave like real functions.

5403bbae9b V4L/DVB (6612): Allow RESET_CLK callback and avoids unneeded loading
TM5600/TM6000 needs clock reset during firmware load. This patch adds the
capability of caling a callback method for this.

Also, avoids uneeded firmware loads.

a82200fb59 V4L/DVB (6605): Add a modprobe option to manually select audio standard
While there's no public API to define audio standard, adds a hack option for
select them. This is needed only for NICAM and A2 firmwares, since AM, BTSC and
EAIJ are already properly handled, on firmware version 2.7.

83fb340b31 V4L/DVB (6595): Corrects printk lines
Make the driver less verbose by default. It adds a debug parameter to make the
driver more verbose.
Also, error messages were using KERN_ERR level, instead of KERN_INFO.
A few printk messages were reviewed to make them more clear.

f380e1d2c9 V4L/DVB (6593): Fix scode table loading
Xceive 2028/3028 has a concept of scode/dcode.
Scode is a table of 16 values (each with 12 bytes i2c sequence).
Dcode is the entry of Scode table that should be used, given a certain
frequency.

The idea is that, depending on what frequency is selected, and according with a
country-based (or standard-based?) table, the Xceive should be "hacked" to
fine-tune that specific frequency.

By default, Scode=0 is used, for undefined frequencies. Also, Scode=0 seems to
be the most used value.

This patch adds the capability of selecting a scode. However, extra work will
be needed to allow auto-selecting the proper scode, for a given set of
frequencies.

I'm not sure what would be the proper way for implementing the dcode selection.
