There are now 4 different versions of the GENPIX USB adapter.  The 
newest 'Skywalker' models are fully self-contained, and need no 
additional hardware to be used.  A very reliable DVB-S card even without 
using any of the alternate modulatations (which this kernel module does 
not currently support)

The following patch adds support for all 4 versions of the genpix
adapter (www.genpix-electronics.com).

FM radio transmission use a preemphasis/deemphasis scheme to reduce
high-frequency noise.  The cx88 audio decoder is supposedly set to no
deemphasis by the current driver.

However, the "no deemphasis" setting doesn't work.  On my chip, cx23883, it
produces the same result as the 75 us time constant.  Maybe the default
settings on the cx23881 are for 50 us?

Since the deemphasis time constant varies by country, allow setting it via a
module parameter.

Get rid of the "CORE" prefix from cx88 printks.  It was only used a few times,
and it makes it look like they're coming from the kernel core or something.

Fix the message, "TV tuner 60 at 0x1fe, Radio tuner -1 at 0x1fe", by adding a
"cx88[0]" prefix to be consistent, and to keep people who grep their dmesg
output for cx88 from missing it.  Get rid of the addresses, which are always
wrong.  The addresses are always set to -1, but because it's an unsigned 8-bit
value, the left shift converts it to the nonsense address 0x1fe.

In the cx8802 driver, some cut and pasted code prefixed lines with "CORE
cx88[0]:", which has been changed to "cx88[0]/2:" like the other printks from
the cx8802 driver.

Also fix some ugly printks in the cx8802 driver that used __FUNCTION__ for
KERN_INFO and KERN_ERR messages.

The changed printks in cx88-mpeg.c also needed lots of whitespace and
80-column fixes.

A bunch of misc changes in cx88-dvb.c and cx88-video.c to add message levels
or a consistent "cx88[?]/2" or "cx88[?]/0" prefix.

A lot of code in cx88-cards.c was only used by cx88-core.c when the core state
is first allocated and initialized.  Moving that task to cx88-cards makes the
driver simpler and the files more self contained.

- Module parameters tuner, radio, card, and latency move to cx88-cards.c
- cx88_boards is made static
- cx88_subids is made static and const
- cx88_bcount is eliminated
- cx88_idcount is eliminated
- cx88_card_list() is made static
- cx88_card_setup_pre_i2c() is made static
- cx88_card_setup() is made static
- cx88_pci_quirks() is moved from cx88-core to cx88-cards
  The function argument "char *name" is made const too
- get_ressources() is moved from cx88-core to cx88-cards, and renamed to
  cx88_get_resources()
- The code to allocate and initialize the core state struct and the chip is
  moved out of cx88-core.c:cx88_get_core() and into a new function in
  cx88-cards.c, cx88_core_create().  This makes both functions simpler.

The cx88 driver state stored the ID of the board type in core->board.  Every
time the driver need to get some information about the board configuration, it
uses the board number as an index into board configuration array.

This patch changes it so that the board number is in core->boardnr, and
core->board is a copy of the board configuration information.  This allows
access to board information without the extra indirection.  e.g.
cx88_boards[core->board].mpeg becomes core->board.mpeg.

This has a number of advantages:
- The code is simpler to write.

- It compiles to be smaller and faster, without needing the extra array lookup
  to get at the board information.

- The cx88_boards array no longer needs to be exported to all cx88 modules.

- The boards array can be made const

- It should be possible to avoid keeping the (large) cx88_boards array around
  after the module is loaded.

- If module parameters or eeprom info override some board configuration
  setting, it's not necessary to modify the boards array, which would
  affect all boards of the same type.

Audio muting for the tuner input was implemented by stopping the 
audio microcontroller and restarting it on unmute. However, it 
appears that this method can actually crash the audio firmware. 
It's rare and seems to happen with NTSC only.

It has been reimplemented by setting to volume to 0. In addition, the
reporting of the mute state has been improved as well: it used to be
impossible to detect whether the audio was muted by the user or if it
was muted due to the microcontroller trying to detect the audio
standard. This is now clearly stated.

The min frequencies of the DVB-C frontends are wrong. 

In Europe, the center frequency of the lowest channel is 50.5MHz and not 
51MHz. All known cards with the stv0297/tda0002x/ves1820 frontend are 
able to tune to this frequency.

I've changed the range to the lowest channel - 1/2 bandwidth and the 
highest channel + 1/2 bandwidth. For the design of the dvb driver, the 
frequency ranges must be part of the tuner and not of the frontend 
itself. The same frontend may be used for different tuners. 

The attached patch does only fix the ranges and not the design.

Add radio support for the Thomson DTT7612 tuner.

This tuner uses a different 1st intermediate frequency than the other radio
tuners supported (a lot of NTSC radio tuners probably need this change too).

Add a new tuner-simple parameter, radio_if.  It selects the 1st IF used for
radio reception.  The radio frequency setting code in tuner-simple now uses
this field, instead of a special case select() block for each tuner with radio
support.

The tuner parameters for tuners that used a 33.3 MHz RIF now set radio_if to 1
in tuner-types.c.

The Thomson DTT7612 gets radio_if = 2, also add has_tda9887 = 1 and
fm_gain_normal = 1.

Add some defines for tda9887 bits that control IF setting in radio mode.

Add a new tda9887 config option, TDA9887_RIF_41_3, that selects a 41.3 MHz
radio IF.

Fix the way tda9887 radio options work.  The driver was modifying the default
radio mode config templates based on the TDA9887_XXXX flags.  This means that
_all_ tuners would get the same settings.  If you had a one tuner than used
TDA9887_GAIN_NORMAL and one that didn't, both would get the setting.  Now the
tda9987 driver just checks if tuner mode is radio and then applies the config
settings directly to the data being sent, just like how all the TV mode
settings already work.

The PLL setting math is made a little more accurate.

And a grammar error in a printk is fixed.
