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.
Some tuners, like xc3028, need to print error messages. Instead of declaring
local macros, create a tuner global macro for printing tuner errors.
To preserve CodingStyle on all tuner_macros, a few CodingStyle violations were
fixed at the other macros:
- lines with more than 80 columns
- two statements at the same line
The patch also removes the CodingStyle violation of having emacs declarations
inside de source code (CodingStyle chapter 18).
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.

V4L/DVB (6586): Remove some dead code and make drive fully V4L2 compatible
There were some vestiges of an old V4L1 I2C driver that were called by em28xx.
This patch removes this dead code, and replaces videodev.h to videodev2.h
Uses the newer ioctl handler at videodev. This patch also cleans up some
bad logic at the driver and do CodingStyle and other cleanups at the
resulting driver.
Also, since VIDIOCMBUF were not working, the V4L1 compat code were removed.
The compat code will eventually be re-inserted, if we find a clean way for
implementing compatibility with the old API.
Allows shared access support for em28xx. Just one userspace application is
allowed to get stream. The other(s) application(s) can change V4L2 controls,
set video standards, etc.
This patch were splited from Markus Rechberger's tree and backported to 2.6.17
by Pádraig Brady.
The original patch were ported to the latest em28xx version and had CodingStyle
corrected to solve the issues pointed by scripts/checkpatch.pl.

the videodevice is not registered yet so nothing can access the hardware

V4L/DVB (6508): ttpci: Rework Kconfig menus and Makefile
The ttpci Kconfig file has bugs that cause it to fail in certain Kconfig
situations. The basic problem is that it selects certain drivers, but does
not depend on the dependencies of those drivers.
See http://article.gmane.org/gmane.comp.video.video4linux/35072
Using the Kconfig file also has some annoyances. For instance one can't turn
off AV7110 support unless you go down several options and first turn off
budget-patch support. Normally user selectable drivers are not forced on like
this.
The "AV7110 cards with Budget Patch" option is disabled if "Budget cards"
isn't on. Normally a driver appears nested under a driver it depends on, but
since drivers that don't depend on "Budget cards" are between the two options,
the config programs can't display the tree correctly.
The Makefile has an issue too. Some modules, ttpci-eeprom and budget-core,
appear in the Makefile under several different config symbols. If more than
one of these symbols is on, they will get added the to list of objects
multiple times. The normal convention is to have a config symbol just the
common object(s) and have the users of the that object either depend on or
select that config symbol.
This patch fixes all these issues. ttpci-eepom is under a new config symbol,
and so is the budget-core module. The four different budget card types appear
as sub-drivers under a main "SAA7146 DVB cards" option. Turning on
budget-patch doesn't force AV7110. Drivers using SAA7146_VV have the
necessary VIDEO_DEV dependency, so that it isn't possible to select SAA7146_VV
without V4L being on.
The tuner sub-module will usually log its type during its _attach() function,
then tuner-core reports which type was attached when control is returned.
In most cases, we expect to see the same message reported from both locations.
We only need to see this second message if debug is enabled.
